1982 Lebanon War

After the 1948 Arab-Israeli war, Lebanon became home to more than 110,000 Palestinian refugees, after their settlements in Palestine and Israel had been depopulated as a result of the war.[25] After its founding in 1964 and the radicalization among Palestinians, which followed the Six-Day War, the PLO became a powerful force, then centred in Jordan. The large influx of Palestinians from Jordan after the Black September conflict caused an additional demographic imbalance within Lebanese society and its democratic institutions established earlier by the National Pact.[26] By 1975, the refugees numbered more than 300,000 and the PLO in effect created an unofficial state-within-a-state, particularly in Southern Lebanon, which then played an important role in the Lebanese Civil War.

Continual violence near the Lebanese border occurred between Israel and the PLO starting from 1968; this peaked, following the relocation of PLO bases to Lebanon after the civil war in Jordan.

The violence between Israel and the PLO peaked during Operation Litani in 1978, provoked by the Coastal Road Massacre which was carried out by Palestinian militants. The United Nations Interim Force in Lebanon (UNIFIL) was created after the incursion, following the adoption of United Nations Security Council Resolution 425 in March 1978 to confirm Israeli withdrawal from Southern Lebanon, restore international peace and security, and help the government of Lebanon restore its effective authority in the area.[27]

As early as 1976, Israel had been assisting Lebanese Christian militias in their sporadic battles against the PLO.[28] During Operation Litani in 1978, Israel established a security zone in southern Lebanon with mostly Christian inhabitants, in which they began to supply training and arms to Christian militias which would later form the South Lebanese Army.[29] But Israel's main partner was to be the Maronite Phalange party, whose paramilitary was led by Bashir Gemayel, a rising figure in Lebanese politics.[29] Gemayel's strategy during the early stages of the Lebanese Civil War was to provoke the Syrians into retaliatory attacks on Christians, such that Israel could not ignore. In 1978, Menachem Begin declared that Israel would not allow a genocide of Lebanese Christians, while refusing direct intervention.[30] Hundreds of Lebanese militiamen began to train in Israel, at the IDF Staff and Command College. The relationship between Israel and the Maronites began to grow into a political-strategic alliance, and members of the Israeli government like Ariel Sharon began to conceive of a plan to install a pro-Israel Christian government in Lebanon, as it was known that Bashir wanted to remove the PLO and all Palestinian refugees in the country.[31]

During the period June to December 1980 the United Nations Interim Force in Lebanon (UNIFIL) recorded an increase in activities along the border zone. No attacks by Palestinian forces on Israel were recorded, while the IDF incursions across the armistice line into Lebanon increased markedly, with minefields being laid, gun posts established, and generally involving numerous violations of Lebanese air-space and territorial waters. This was formally protested by the Lebanese government to the UN Security Council and General Assembly in several communications as violations by Israel of United Nations Security Council Resolution 425. During the same period Israel protested numerous attacks by Palestinian forces, unrelated to the Lebanese border zone.[32]

In his report for the period of 12 December 1980 to 12 June 1981 on UNIFIL activities, the Security Council Secretary General noted that infiltrations into the border zone by Palestinian armed forces had decreased relative to the previous six months.[33] In contrast the IDF had launched various attacks on Lebanese territory often in support of the Lebanese Christian militia. In doing so Israel had violated UN Security Council resolution 425 on hundreds of occasions [paragraph 58]. Where the initiator(s) of attacks could be identified in the report, in 15 cases Palestinian militants were to blame while on 23 occasions the Militia and/or the IDF were the instigators, the latter also being responsible for the most violent confrontation of the period on 27 April [paragraph 52].

In the subsequent period 16 June to 10 December 1981,[34] a relative quiet was reported continuing from 29 May 1981 until 10 July. This was broken when "Israeli aircraft resumed strikes against targets in southern Lebanon north of the UNIFIL area. (The Israeli strikes) led to exchanges of heavy firing between armed elements (Palestinians), on the one hand, and IDF and the de facto forces (Christian Militia) on the other. On 13 and 14 July, widespread Israeli air-strikes continued. Armed elements (Palestinians) fired into the enclave and northern Israel." Israeli-initiated attacks had led to rocket and artillery fire on northern Israel. This pattern continued in the coming days.

Israel renewed its air strikes in an attempt to trigger a war that would allow it to drive out the PLO and restore peace to the region.[35] On 17 July, the Israel Air Force launched a massive attack on PLO buildings in downtown Beirut. "Perhaps as many as three hundred died, and eight hundred were wounded, the great majority of them civilians."[36] The Israeli army also heavily targeted PLO positions in south Lebanon without success in suppressing Palestinian rocket launchers and guns. As a result, thousands of Israeli citizens who resided near the Lebanese border headed south. There patterns of Israeli-initiated airstrikes and Palestinian retaliations with attacks on northern Israel are in contrast with the official Israeli version "A ceasefire declared in July 1981 was broken: the terrorists continued to carry out attacks against Israeli targets in Israel and abroad, and the threat to the northern settlements became unbearable."[37]

On 24 July 1981, United States Undersecretary of State Philip Habib brokered a ceasefire badly needed by both parties,[34] the best achievable result from negotiations via intermediaries, aimed at complying with the decisions of UN Security Council resolution 490. The process was complicated, requiring

shuttle diplomacy between Damascus, Jerusalem, and Beirut, United States. Philip Habib concluded a ceasefire across the Lebanon border between Israel and the PLO. Habib could not talk to the PLO directly because of Kissinger's directive, so he used a Saudi member of the royal family as mediator. The agreement was oral – nothing could be written down since Israel and the PLO did not recognize each other and refused to negotiate with each other – but they came up with a truce. ... Thus the border between Lebanon and Israel suddenly stabilized after over a decade of routine bombing.[38]

Between July 1981 and June 1982, as a result of the Habib ceasefire, the Lebanese-Israeli border "enjoyed a state of calm unprecedented since 1968."[24] But the 'calm' was tense. US Secretary of State, Alexander Haig filed a report with US President Ronald Reagan on Saturday 30 January 1982 that revealed Secretary Haig's fear that Israel might, at the slightest provocation, start a war against Lebanon.[39]

The 'calm' lasted nine months. Then, on 21 April 1982, after a landmine killed an Israeli officer while he was visiting a South Lebanese Army gun emplacement in Taibe, Lebanon, the Israeli Air Force attacked the Palestinian-controlled coastal town of Damour, killing 23 people.[40] Fisk reports further on this incident: "The Israelis did not say what the soldier was doing ... I discovered that he was visiting one of Haddad's artillery positions (Christian militia) and that the mine could have been lain [sic] as long ago as 1978, perhaps even by the Israelis themselves".

On 9 May 1982, Israeli aircraft again attacked targets in Lebanon. Later that same day, UNIFIL observed the firing of rockets from Palestinian positions in the Tyre region into northern Israel, but none of the projectiles hit Israeli towns[41] – the gunners had been ordered to miss.[36] Major-General Erskine (Ghana), Chief of Staff of UNTSO reported to the Secretary-General and the Security Council (S/14789, S/15194) that from August 1981 to May 1982, inclusive, there were 2096 violations of Lebanese airspace and 652 violations of Lebanese territorial waters.[42][43] The freedom of movement of UNIFIL personnel and UNTSO observers within the enclave remained restricted due to the actions of Amal and the South Lebanon Army under Major Saad Haddad's leadership with the backing of Israeli military forces.[43]

Prior to establishing ceasefire in July 1981, U.N. Secretary-General Kurt Waldheim noted: "After several weeks of relative quiet in the area, a new cycle of violence has begun and has, in the past week, steadily intensified." He further stated: "There have been heavy civilian casualties in Lebanon; there have been civilian casualties in Israel as well. I deeply deplore the extensive human suffering caused by these developments." The President of the U.N. Security Council, Ide Oumarou of Niger, expressed "deep concern at the extent of the loss of life and the scale of the destruction caused by the deplorable events that have been taking place for several days in Lebanon".[44][45]

From the ceasefire, established in July 1981, until the start of the war, the Israeli government reported 270 militant attacks by the PLO in Israel, the occupied territories, and the Jordanian and Lebanese border (in addition to 20 attacks on Israeli interests abroad).[46]

In Ariel Sharon's biography by his son, Gilad Sharon, the author referring to the Habib ceasefire, comments: "However, the agreement was explicit only regarding preventing terror from Lebanon, which is why my father encouraged the cabinet not to accept the offer as presented by the Americans."[47]

The cease-fire, as both the PLO and the Americans saw it, did not include terror attacks stemming from Lebanon and carried out against Jews in Europe and other locales. In a meeting my father had with Alexander Haig and Philip Habib on 25 May 1982, Habib repeated what he had already said many times before: "Terrorist attacks against Israelis and Jews in Europe are not included in the cease-fire agreement.

Arafat pressured the radical factions to maintain the ceasefire because he did not wish to provoke the Israelis into an all-out attack. The PLO acceptance of the ceasefire had led to dissension even within Fatah itself. A faction sympathetic to Abu Nidal forced a military confrontation, with accompanying arrests and executions — an event unprecedented in PLO internal disputes'. Arafat even attempted to distance himself from Palestinian unrest on the West Bank to prevent an Israeli attack. In contrast, Begin, Sharon and Eitan were searching for any excuse to neutralize their military opponents through a breach of the ceasefire. They believed that Arafat was buying time to build up his conventional forces. The Israeli interpretation of the conditions for the ceasefire placed responsibility for any act of Palestinian violence on Arafat's shoulders. It presumed that Arafat had complete control, not only over all factions within the PLO such as the rejectionist Popular Front of George Habash, but also over those outside such as Abu Nidal's Fatah Revolutionary Council and Ahmed Jibril's Popular Front — General Command. Moreover, in Begin's eyes, the ceasefire was not geographically limited to the Lebanese border. He argued that if Palestinian terrorism struck internationally, then this too would be regarded as a breach of the ceasefire. Begin thus took a stand-off in a local battle as applying to the entire war anywhere in the Middle East or any incident internationally. Eitan commented that there was no difference if a militant threw a grenade in Gaza or fired a shell at a Northern settlement — all such acts broke the ceasefire. Sharon similarly did not wish to draw distinctions between different Palestinian factions, since all blame had to be attached to the PLO. He dismissed attempts at more rational evaluation as masking the real issue. In a speech to a Young Herut conference in April 1982, he accused those who tried to take a more objective standpoint of erecting 'a protective wall around the PLO inside and outside Israel'.[48]

Further support comes from George Ball, that the PLO had observed the ceasefire.[49] Israel, he said, continued looking for the "internationally recognized provocation" that Secretary of State Alexander Haig said would be necessary to obtain American support for an Israeli invasion of Lebanon.[50] Secretary Haig's critics have accused him of "greenlighting" the Israeli Invasion of Lebanon in June 1982.[51] Haig denies this and says he urged restraint.[52] In the biography of ceasefire broker Philip Habib, Alexander Haig is cited as leaving the worst impression of all in the lead up to Israel's Lebanon invasion:

Haig thus comes off very badly: not a team player, not able to keep the rest of the administration informed of what was going on beforehand, not willing to tell anyone in the White House why Sharon was so confident during the invasion, hoping that Reagan's special envoy would fail in his mission, and having little sense of what the national security of the United States required—which was not a confrontation between Israeli and Soviet tanks on the road from Beirut to Damascus.[53]

The American reaction was that they would not apply any undue pressure on Israel to quit Lebanon as the Israeli presence in Lebanon may prove to be a catalyst for the disparate groups of Lebanon to make common cause against both Syrian and Israeli forces. Haig's analysis, which Ronald Reagan agreed with, was that this uniting of Lebanese groups would allow President Elias Sarkis to reform the Lebanese central Government and give the Palestinian refugees Lebanese citizenship.[54] Additional evidence that the United States approved the Israeli invasion comes from longtime CIA analyst Charles Cogan, who says that he was in the room during a May 1982 meeting in The Pentagon during which Sharon explained to Secretary of Defense Caspar Weinberger "in great detail how the Israelis were going to invade Lebanon ... Weinberger just sat there and said nothing."[55]

According to Avi Shlaim, the real driving force behind the Israeli invasion to Lebanon was the defense minister Ariel Sharon. One of his aims was the destruction of PLO military infrastructure in Lebanon and undermining it as a political organization, in order to facilitate the absorption of the West Bank by Israel. The second aim was the establishment of the Maronite government in Lebanon, headed by Bashir Gemayel and signing the peace treaty between two countries, the third aim was the expelling of the Syrian Army from Lebanon. Also, according to Shlaim, with the completion of Israeli withdrawals from Sinai in March 1982, under the terms of the Egyptian-Israeli Peace Treaty, the Likud-led government of Israel hardened its attitude to the Arab world and became more aggressive.[56]

According to Zeev Maoz in Defending the Holy Land: A Critical Analysis of Israel's National Security and Foreign Policy the goals of the war were primarily developed by then Minister of Defense Ariel Sharon and were fourfold: 1) "Destroy the PLO infrastructure in Lebanon, including the PLO headquarters in Beirut." 2) "Drive Syrian forces out of Lebanon." 3) "Install a Christian-dominated government in Lebanon, with Bashir Gemayel as President." 4) "Sign a peace treaty with the Lebanese government that would solidify the informal Israeli-Christian alliance and convert it into a binding agreement."[57] George Ball testified before the U.S: Senate's Foreign Affairs Committee that Sharon's long-term strategy, as revealed in conversations, was one of "squeezing the Palestinians out of the West Bank . .allowing only enough of them to remain for work."[58]

The military plan with the code name "Big Pines", prepared by IDF, envisaged invasion to Lebanon up to the highway Damascus-Beirut and linking with Maronite forces. It was first presented to Israeli cabinet on 20 December 1981 by Begin, but rejected by the majority of ministers. According to Avi Shlaim, Sharon and chief of staff Rafael Eitan, realizing that there was no chance in persuading the cabinet to approve a large-scale operation in Lebanon, adopted a different tactic and intended to implement "Operation Big Pines" in stages by manipulating enemy provocations and Israeli responses.[59]

On 3 June 1982 Israel's ambassador to the United Kingdom, Shlomo Argov was shot and seriously wounded in London by militants belonging to the Iraqi-backed Abu Nidal militant organization. The attack was ordered by the Iraqi Intelligence Service.[60][61][62] Following the attack, the assassins drove to the Iraqi embassy in London, where they deposited the weapon.[63] In his memoirs, Sharon stated that the attack was "merely the spark that lit the fuse".[64] Israeli prime Minister Begin used this as the "internationally recognized provocation" necessary to invade Lebanon. The fact that the Abu Nidal organization was the longtime rival of PLO, that its head was condemned to death by the PLO court, and that the British police reported that PLO leaders were on the "hit list" of the attackers did not deter Begin. Iraq's motives for the assassination attempt may have been to punish Israel for its destruction of Iraq's nuclear reactor in June 1981, and to provoke a war in Lebanon that Iraqi leaders calculated would be detrimental to the rival Ba'ath regime in Syria—whether Syria intervened to help the PLO or not![65]

At the Israeli Cabinet meeting the following day, both Begin and Eitan belittled intelligence reports that the likely culprit was the Abu Nidal group. Begin cut short his own advisor on terrorism, arguing that all Palestinian militants were members of the PLO, while Eitan ridiculed the intelligence staff for splitting hairs and demanded to strike at the PLO. Yet Abu Nidal had broken with Arafat and PLO in 1974 over a fundamental principle: namely, that the Palestinian national movement would adopt a phased piecemeal approach to secure a Palestinian state and embark on a political path. The lack of understanding of the difference between Palestinian groups and the total ignorance of Palestinian politics on the part an overwhelming majority of Israelis and Jews played into the hands of those who did not wish to distinguish between the PLO and the Abu Nidal group. Thus, instead of an initiative to locate the Abu Nidal group in Damascus or Baghdad, the plan to invade Lebanon was activated.[48]^:119–120

The PLO denied complicity in the attack, but Israel retaliated with punishing air and artillery strikes against Palestinian targets in Lebanon, including the PLO camps. Sabra and the Shatila refugee camp were bombed for four hours and the local "Gaza" hospital was hit there. About 200 people were killed during these attacks.[66] The PLO hit back firing rockets at northern Israel causing considerable damage and some loss of life. According to another source, twenty villages were targeted in Galilee and 3 Israelis were wounded.[67]

According to Shlaim, Yasser Arafat, at that time being in Saudi Arabia, told the Americans through the Saudis that he was willing to suspend cross-border shelling. But that message was disregarded by the Israeli government. President Reagan also sent a message to Begin urging him not to widen the attack.[67]

On 4 June the Israeli cabinet authorized a large scale invasion.[68][69] Begin referred to the operation as self-defense to "avoid another Treblinka".[70]

On 6 June 1982, Israeli forces under direction of Defense Minister Ariel Sharon launched a three-pronged invasion of southern Lebanon in "Operation Peace for Galilee". Roughly 60,000 troops and more than 800 tanks, heavily supported by aircraft, attack helicopters, artillery, and missile boats, crossed the Israel–Lebanon border in three areas. Simultaneously, Israeli armor, paratroopers, and naval commandos set sail in amphibious landing ships from Ashdod towards the Lebanese coast north of Sidon. Israel's publicly stated objective was to push PLO forces back 40 kilometers (25 mi) to the north.

Israeli troops driving towards Beaufort Castle, 1982

The westernmost Israeli force was to advance up the coastal road to Tyre. Its mission was to bypass Tyre and destroy three PLO camps in the area, then move up the coast towards Sidon and Damour, while Israeli forces would simultaneously conduct an amphibious landing north of Sidon to cut off the retreat of PLO forces there. In the center, two divisions were to advance both north and south of the high ground overlooked by Beaufort Castle, which was being used as a PLO stronghold, and take the road junction at Nabatieh, while an elite reconnaissance battalion was to take the castle itself. The two divisions were then to split, with one heading west to link up with the forces along the coast, and another towards Jezzine and from there along the right flank of Syrian forces in the Bekaa Valley. The easternmost Israeli force, the largest of the three, advanced into the Bekaa Valley. Its mission was to prevent Syrian reinforcements from being sent and to stop Syrian forces from attempting to interfere with the operation on the coastal road.[71]

Israeli troops in Lebanon, 1982

The advance along the coastal road was preceded by heavy artillery bombardment and airstrikes, but quickly became bogged down and was soon behind schedule. The narrowness of the road forced a slow advance, and Israeli armor became stuck in a large traffic jam. Several armored vehicles were knocked out by PLO fighters with anti-tank weaponry hiding in three groves along the road. One of the lead battalions, which was supposed to bypass Tyre and establish a blocking position to the north of the city, made a wrong turn and found itself in the center of the city, where it was ambushed. At eight in the evening the force finally crossed the Litani River and headed towards Sidon. In the central sector, the mission went as planned. The two Israeli divisions bypassed Beaufort Castle on both sides. Although an order to postpone the capture of Beaufort Castle was issued, it did not reach Israeli forces in time to prevent the operation, and Israeli troops of the Golani Brigade captured the castle in the fiercely-fought Battle of the Beaufort. The road junction at Nabatieh was also secured by the end of the first day. Meanwhile, the easternmost force penetrated into the Bekaa Valley and bore down on the Syrian positions. One division bypassed Mount Hermon via a road bulldozed by Israeli military engineers and cleared the town of Hasbaiya before swinging right and advancing towards Rachaiya. Though Israeli forces halted in the floor of the valley, they were flanking Syrian forces from the east and west. The Syrians put up minimal resistance and conducted some harassing artillery fire. By the end of the first day, the operation had gone almost entirely according to plan, though the advance along the coastal road was behind schedule.[71]

Despite the delays, the Israeli advance along the coastal road continued steadily. This advance was supported by heavy air attacks against PLO positions that included the use of cluster bombs. Israeli missile boats also employed 76mm cannons to destroy targets along the coast, firing 3,500 shells during ten days of fighting. Israeli armor continued to advance towards Sidon, while other Israeli infantry attacked the three Palestinian refugee camps in the area that were used as PLO bases: Rashidiya, Burj ash-Shamali, and al-Bass. The camps were all crisscrossed with networks of bunkers, trenches, and firing positions. The Israelis took each camp section by section using the same method: warnings were blared by loudspeaker urging civilians to leave, before air and artillery bombardment commenced, followed by an infantry assault. Israeli infantry had to engage in fierce urban combat in narrow streets. The PLO defenders put up strong resistance and sometimes used civilians as human shields. It took four days of combat to secure Rashidiya and three days to secure the other two camps. At the same time, an Israeli amphibious operation was conducted north of Sidon, beginning with a diversionary bombardment of targets away from the landing zone by missile boats and aircraft. Two groups of commandos from the Shayetet 13 naval commando unit then came ashore to probe enemy defenses and secure the landing site, one of which swam to the mouth of the Awali River and another which came ashore on the landing beach in rubber dinghies. After a brief gunbattle with armed Palestinians, the main landings began, with paratroopers coming ashore in rubber dinghies to establish a beachhead followed by three landing craft that unloaded troops and armor. Over the following days, the three landing ships would run between Israel and Lebanon, shuttling more troops and armor onto the beachhead. The PLO response was limited to ineffective mortar fire, while Israeli missile boats and aircraft attacked Palestinian positions in response, and in total, about 2,400 soldiers and 400 tanks and armored personnel carriers were landed. From the beach, these forces advanced on Sidon, supported by naval gunfire from missile boats. At the same time, Israeli forces in the central sector advanced towards Jezzine while those in the eastern sector remained in place, but began setting up heavy artillery positions that put Syrian SAM units in artillery range.[72][24][71]

Meanwhile, Israeli forces advancing along the coastal road reached the outskirts of Sidon, but were delayed by heavy resistance in the main streets and the Ain al-Hilweh refugee camp on the southeastern edge of the city, and after an attempt by paratroopers to capture the city center and secure the south-north route through the city failed, the city was bypassed via a detour through the hills to the east. After linking up with the forces that had landed north of Sidon, while another force of paratroopers and armor with heavy air and artillery support advanced through central Sidon and cleared a south-north route through the city in fierce fighting. Another Israeli division passed through the city to link up with the forces north of Sidon.[24]

A Syrian tank burning on the road outside Jezzine

In the center, most Israeli forces advancing towards Jezzine bypassed the town to continue advancing towards the main highway in the area, leaving a blocking force in the area that was soon joined by an armored brigade. Fighting broke out in Jezzine between the Israelis and Syrian forces holding the town. In the Battle of Jezzine, Israeli forces consisting of two tank battalions supported by a reconnaissance company and engineering platoon took Jezzine in a fierce daylong battle against a Syrian battalion, then repulsed a fierce counterattack by dozens of Syrian commandos during the night in combat that lasted until dawn. Meanwhile, Israeli forces continued to advance along the Syrians' right flank.

Israeli forces advancing along the coast also completed the capture of Sidon. Paratroopers attacked the Kasbah while a combined force of Golani Brigade infantry and tanks attacked Ain al-Hilweh. The Kasbah was secured in three days; the paratroopers advanced cautiously and managed to take it without suffering any casualties. However, the fighting at Ain al-Hilweh was to prove some of the fiercest of the entire war. The camp was heavily fortified and defended by PLO fighters and Islamic fundamentalists. The defenders fought fiercely over every alley and house, with civilians who wanted to surrender shot by the fundamentalists. The Israeli advance was slow and was supported by massive air and artillery bombardment. The IDF employed its previous tactics of urging civilians to leave with loudspeakers before attacking an area. It took about eight days for the camp to fall, with the battle culminating in a last stand by the defenders at the camp mosque, which was blown up by the IDF.[73]

In an effort to establish air superiority and greater freedom of action, the Israeli Air Force launched Operation Mole Cricket 19 on 9 June. During the course of the operation, the Israeli Air Force scored a dramatic victory over the Syrians, shooting down 29 Syrian planes and also destroying 17 Syrian anti-aircraft missile batteries, employing electronic warfare methods to confuse and jam the Syrian radars.[13] The Israelis' only known losses were a single UAV shot down and two fighter jets damaged. Later that night, an Israeli air attack destroyed a Syrian armored brigade moving south from Baalbek, and the IAF attacked and destroyed six more Syrian SAM batteries the following day. The easternmost Israeli force, which had been stationary, resumed its advance forward up the Bekaa Valley.[71]

In the center, Israeli forces were ambushed by the Syrians as they approached Ain Zhalta, and were pinned down by Syrian forces firing from superior positions. The Israelis were bogged down, and an infantry battalion was sent in by helicopter to reinforce them. The town was only captured after a two-day armored and infantry battle. The battle cost the Israelis 11 killed and 4 tanks, while the Syrians lost approximately 100 killed and 35 tanks. After Ain Zhalta fell, the Israelis advanced to the town of Ain Dara, which overlooked the Beirut-Damascus highway, and captured the heights overlooking the town. Along the road to Ain Dara, the Israelis encountered Syrian tank and commando units, and found themselves bogged down as the Syrians took advantage of the terrain. The Israelis called in air support, and Israeli attack helicopters that took advantage of ravines to fly in low beneath their targets to gain an element of surprise proved particularly effective against Syrian tanks. After a daylong battle, the Israelis had surrounded Ain Dara and were in a position to strike on the highway.[13]

In the east, Israeli forces advanced along four main routes towards Joub Jannine, along both sides of the Qaraoun reservoir. The Syrians resisted fiercely. Syrian infantrymen armed with anti-tank weapons staged ambushes against Israeli tanks, and Syrian Gazelle helicopters armed with HOT missiles proved effective against Israeli armor. However, the Israelis managed to capture the valley floor, and the Syrians retreated. The Israelis captured Rachaiya, advanced through Kfar Quoq, and took the outskirts of Yanta. Joub Jannine also fell to the Israelis. The extent of Israeli advances ensured that Syrian reinforcements were blocked from deploying west of the Qaraoun reservoir. An Israeli armored battalion then probed past Joub Jannine to the town of Sultan Yacoub, and was ambushed by Syrian forces lying in wait. In the Battle of Sultan Yacoub, the Israelis fought fiercely to extricate themselves, and called in reinforcements and artillery fire to cover the withdrawal. After six hours, the Israelis managed to retreat, having lost 10 tanks and 3 armored personnel carriers. In addition, another major air battle erupted in which the Israeli Air Force shot down 25 Syrian jets and 4 helicopters.[13]

A destroyed airliner at Beirut Airport, 1982.

To the west, as IDF troops mopped up remaining resistance in Tyre and Sidon, the Israeli advance on Beirut continued, and Syrian tank and commando units were then deployed south of Beirut to reinforce the PLO. When the Israelis reached the Beirut suburb of Kafr Sill, they met a joint Syrian-PLO force for the first time, and fought a difficult battle to take it. The IDF temporarily halted its advance in the western sector at Kafr Sill.[13]

On 11 June, Israel and Syria announced that they had agreed to a cease-fire at noon, which would not include the PLO. The cease-fire was to come into effect at noon. Just before the cease-fire was to take effect, the Syrians moved a column of T-72 tanks so as to position it against Israeli forces in the valley. Israeli infantry teams armed with BGM-71 TOW anti-tank missiles ambushed the Syrian column, destroying 11 tanks. Another air battle also occurred, with the Israelis shooting down 18 more Syrian jets.[74]

The Israeli advance on Beirut pressed forward in the west, reaching Khalde on 11 June. Six miles south of Beirut, the town was the last PLO position in front of Beirut Airport. The Israelis, who stood on the outskirts of Beirut, advanced towards the airport, and engaged in frequent combat with PLO and Syrian units as Israeli warplanes continued to bomb PLO positions in Beirut. The PLO's situation gradually grew worse as the Israeli advance gained ground, threatening to trap the PLO and a Syrian brigade deployed with them in the city. With the Israelis advancing on the south and the eastern sector of Beirut held by Lebanese Christian forces, the only way out was on the Beirut-Damascus highway, and the Israelis were building up forces at Ain Dara in the eastern sector, which were in a position to strike at the highway and block any PLO attempt to escape. On 12 June, the Israeli-Syrian cease-fire was extended to the PLO. As the Israeli advance halted, the Israelis turned their attention to the zone they already occupied in southern Lebanon, and began a policy to root out any PLO remnants. Israeli troops began searches for arms caches, and suspected PLO members were systematically rounded up and screened, and taken to a detention camp on the Amoun Heights.[13]

On 13 June, less than twelve hours after the Israeli-PLO ceasefire had gone into effect, it fell apart, and heavy fighting erupted around Khalde. As the fighting raged, an IDF armored unit struck northeast, attempting to bypass Khalde and advance on Baabda, which overlooked the airport and could be used as another staging point to cut the Beirut-Damascus highway. By 14 June, Syrian forces were being deployed to Khalde. Syrian units in Beirut and three commando battalions armed with anti-tank weaponry took up defensive positions southwest of the airport to block any Israeli attempt to capture it. The Israelis attempted to flank these defenses by moving off the road past Shuweifat, up a narrow, steep, and winding road towards Baabda, but were ambushed by a Syrian commando battalion. The Syrians attacked Israeli armor with rocket-propelled grenades and anti-tank missiles at close range. Israeli infantry dismounted and engaged the Syrians. Fierce fighting took place, with the Israelis calling in artillery at very close range to themselves. The Israelis advanced relentlessly, and after fourteen hours of fierce combat that raged up through Ain Aanoub and Souq el-Gharb, they broke through the Syrian positions and entered Baabda. The IDF then immediately sent reinforcements to the column in Baabda to enable it to carry out further operations. From Baabda, the Israeli force split into three columns, one of which struck across the highway and entered the mountainous area to the northeast, one swung west and took up positions in the steep hills west of Beirut, and one turned toward Kahale, which was further down the highway. To the south, the IDF drove PLO forces out of Shuweifat, but no major battles occurred. The Israelis had now cut the Beirut-Damascus highway, cutting off all PLO and Syrian forces in the city.[13]

On 15 June, Israel offered free passage to all Syrian forces in Beirut if they would withdraw from the city to the Bekaa Valley in the east, but the Syrian government refused and sent further reinforcements to its units along the highway and north of the highway near Beirut. The Israelis faced Syrian strongpoints reinforced by armor and artillery all along the highway. However, between 16 June and 22 June, the fighting was limited to artillery duels and minor firefights between Israeli and Syrian forces, as both sides reinforced their troops.[13]

As the two sides prepared for combat, the IDF deemed capturing the Beirut-Damascus highway to be of critical importance. With the Syrians in control of most of the highway, occupying the towns along the highway and to the north, the Israelis could not prevent Syrian and PLO forces from escaping or launch further operations into Beirut without risking a Syrian flanking attack, and the Israelis also wanted a clear transit to Christian-held eastern Beirut.

On 22 June, the IDF launched an operation to capture the highway. The Israeli Air Force flew highly effective missions against Syrian positions and vehicles, with Israeli pilots reporting 130 enemy vehicles destroyed in a single air attack alone. Israeli long-range artillery targeted Syrian strongpoints to the north. Israeli armored forces with artillery support attacked Syrian positions along the highway, with the objective of driving them from the highway all the way back to the edge of the Bekaa Valley. With air and artillery support mostly limited to targets north of the highway, the fighting was fierce, especially to the south. By the end of the day, Israel accepted an American request for a cease-fire and halted its offensive, but the cease-fire collapsed the following day and the fighting resumed. As the Israelis pushed forward, and managed to trap a large Syrian force, Syrian defenses began to collapse. For the first time in the war, Syrian troops began to break and run. At Aley, which was defended by Iranian volunteers sent to fight for the PLO, the Israelis encountered fierce resistance.

The Israelis managed to push to the eastern Bekaa Valley, and on 24 June, began to shell the outskirts of Chtaura, which was at the northern mouth of the Bekaa Valley and served as headquarters of all Syrian forces there. It was also the last major obstacle before the Syrian border, as well as Syria's capital Damascus itself. The Israelis managed to reach the mountain pass near the village of Dahr el-Baidar, which was the last obstacle before Cthaura. The Syrians fought fiercely to hold the pass, and the Israeli advance halted, with the Israelis holding their ground and harassing the Syrians with artillery fire. By 25 June, with the remaining Syrian positions on and north of the highway no longer tenable, the Syrians withdrew. The Israelis allowed the withdrawal to occur but conducted artillery harassment and continued to shell the outskirts of Chtaura. The Syrians attempted to deploy a SAM battery in the Bekaa Valley at midnight, but Israeli intelligence detected this, and the battery was destroyed in an Israeli air attack. By the end of the day, a cease-fire was announced. The Israelis stopped at their present positions.[13]

The Siege of Beirut had begun on 14 June: Israeli forces had completed the encirclement of the city the previous day. The Israelis chose to keep the city under siege rather than forcibly capture it, as they were unwilling to accept the heavy casualties that the heavy street fighting required to capture the city would have resulted in. Israeli forces bombarded targets within Beirut from land, sea, and air, and attempted to assassinate Palestinian leaders through airstrikes. The Israeli Navy maintained a blockade on the port of Beirut with a ring of missile boats and patrol boats supported by submarines.[75] The siege lasted until August, when an agreement was reached in August 1982. More than 14,000 PLO combatants evacuated the country in August and September, supervised by the Multinational Force in Lebanon, an international peacekeeping force with troops from the United States, United Kingdom, France, and Italy. About 6,500 Fatah fighters relocated from Beirut to Jordan, Syria, Iraq, Sudan, both North and South Yemen, Greece, and Tunisia—the latter of which became the new PLO headquarters.[76] Israel withdrew its forces from west Beirut on 29 September, officially ending Operation Peace for Galilee. Philip Habib, Ronald Reagan's envoy to Lebanon, provided an understanding (i.e., assurance) to the PLO that the Palestinian civilians in the refugee camps would not be harmed. However, increased hostilities against the US resulted in the April 1983 United States Embassy bombing. In response, the US brokered the May 17 Agreement, in an attempt to stall hostilities between Israel and Lebanon. However, this agreement eventually failed to take shape, and hostilities continued. These attacks were attributed to Iranian-backed Islamist guerrillas. Following this incident, international peacekeeping forces were withdrawn from Lebanon.

IDF forces totalled 78,000 men, 1,240 tanks and 1,500 armoured personnel carriers. IDF troops were deployed in five divisions and two reinforced brigade-size units. The IDF maintained additional forces on the Golan Heights as an area reserve.[92] IDF forces were divided into three main axis of advances called sectors:[92][95]

• Coastal Sector, (from Rosh Hanikra north to Tyre, Sidon, Damour and Beirut.) – Forces included Division 91 with three brigades including the 211th and the Golani Brigade. The 35 Paratroop Brigade and the Na'hal 50th Paratroop Battalion were attached to the division as needed. The Israeli Navy provided naval interdiction, shore gunfire support and landed a mixed brigade from Division 96 at the mouth of the Awali River near Sidon. Israeli Naval commandos had landed there previously.[92][95]
• Central Sector (from Beaufort Castle to Nabatiyeh) – Jezzine was the main objective and then on to Sidon to link up with the coastal forces. IDF forces included the Divisions 36 and 162.[92]
• Eastern Sector (from Rachaiya and Hasbaiya through the Bekaa Valley around Lake Qaraoun) – IDF forces included Divisions 90 and 252, the Vardi Force and the Special Maneuver Force which was composed of two brigades of Infantry and paratroops who were trained for anti-tank operations. These forces were primarily used to contain the Syrians with orders not to initiate combat against them.[92][95]

Syrian anti-tank teams deployed French-made Milan ATGMs during the war in Lebanon in 1982.

The Syrian Army deployed over 30,000 troops in Lebanon.[92][96]

The largest concentration was in the Bekaa Valley where the 1st Armoured Division consisting of the 58th Mechanised and the 76th and 91st Armoured Brigades. The 62nd Independent Armored Brigade and ten commando battalions were also assigned to the division. Syria deployed around 400 tanks in the Bekaa Valley. 19 surface-to-air missile batteries, including SA6's, were also deployed in the Bekaa Valley.

In Beirut and the Shouf Mountains were the 85th Infantry Brigade, the PLA, As-Sa'iqa and 20 commando battalions. Syria deployed around 200 tanks in this area. Their primary mission was to protect the Beirut-Damascus Highway, which was Syria's primary supply line in the region.[92]

Lebanese Army – By 1982 the Lebanese Army had largely disintegrated and what was left was a Christian-staffed force of about 10,000 men in five brigades (the 5th, 7th, 8th, 9th, and 10th) plus some smaller independent units. The Lebanese Army was officially neutral and followed the orders of the Lebanese government, but provided tacit and active support to the Lebanese Front.[96] The Army had lost much of its heavy equipment due to defections of its units.[97]

A Lebanese national army unit of 1,350 was under the operational control of the UNIFIL commander, HQ located at Arzun with sub-units attached to UNIFIL Battalions.[43][92]

Lebanese Navy: The mostly Christian manned force operated several patrol boats and was loyal to the government. It played little or no part in the war.

Lebanese Air Force: This largely Christian force operated a force of jet fighters, helicopters and other aircraft and it too played little part in the war.

Internal Security Forces: the national police and internal security force of Lebanon.

Palestinian Liberation Organization forces continued to grow in Lebanon, with full-time military personnel numbering around 15,000 fedayeen, although only 6,000 of these – including 4,500 regulars – deployed in the south. They were armed with 80 aging tanks, many of them no longer mobile, and with 100 to 200 pieces of artillery. According to Israeli analysts Schiff and Ya'ari (1984), the PLO more than quadrupled its artillery from 80 cannons and rocket launchers in July 1981 to 250 in June 1982.[98] The same authors also refer to Israeli intelligence estimates of the number of PLO fighters in southern Lebanon of 6,000 as

divided into three concentrations; about 1,500 south of the Litani River in the so-called Iron Triangle (between the villages of Kana, Dir Amas, and Juya), Tyre, and its surrounding refugee camps; another 2,500 of the Kastel Brigade in three districts between the Litani and a line running from Sidon to northeast of Nabatiye; and a third large concentration of about 1,500–2,000 men of the Karameh Brigade in the east, on the slopes of Mount Hermon.[99]

PLO primary forces consisted of three conventional brigades – each of 2,000 to 2,500 men – and of seven artillery battalions.[100] Each brigade comprised contingents of the many PLO factions. The Yarmouk Brigade was stationed along the coastal strip while the Kastel Brigade was in the south. The Karameh Brigade was stationed on the eastern slopes of Mount Hermon in the area called Fatahland.

The PLO had around 15,000 to 18,000 fighters (of whom about 5,000 to 6,000 were alleged to be foreign mercenaries (or volunteers) from such countries as Libya, Iraq, India, Sri Lanka, Chad and Mozambique[101]) deployed as follows:[92]

• 6,000 in the Beirut, Ba'abda and Damour area
• 1,500 in Sidon
• 1,000 between Sidon and Tyre
• 1,500 in Tyre
• 1,000 deployed from Nabatiyeh to Beaufort Castle
• 2,000 in Fatahland
• around 1,000 in the UNIFIL Zone

Heavy weapons consisted of about 60 T-34, T-54 and T-55 tanks (most of them dug in as pillboxes), up to 250 130mm and 155 mm artillery, many BM21 Katyusha multiple-rocket launchers plus heavy mortars.[102]

Palestinian groups in the radical Rejectionist Front fought on the Muslim-leftist side. The alliance did nothing to improve cooperation between member factions, and internecine bloodshed continued. The following were members of the Rejectionist Front:

• Arab Liberation Front (ALF) Pro-Iraqi
• As-Sa'iqa (also known as the Vanguard for the Popular Liberation War), a Palestinian Ba'athist political and military faction created and controlled by Syria.
• Abu Nidal's Fatah-Revolutionary Council
• Democratic Front for the Liberation of Palestine (DFLP)
• Palestine Liberation Army (PLA) Includes the Popular Liberation Forces (Arabic, quwwat at-tahrir ash-sha'biyya), better known as the Yarmouk Brigade, a PLA Commando force.
• Palestinian Popular Struggle Front (PPSF)
• Popular Front for the Liberation of Palestine (PFLP)
• Popular Front for the Liberation of Palestine - General Command (PFLP-GC)

Some, such as As-Sa'iqa, the Arab Liberation Front, the Palestine Liberation Army and the Popular Front for the Liberation of Palestine-General Command (PFLP-GC) were essentially mercenary armies for foreign governments (Syria, Iraq, and Libya, respectively).[96]

• South Lebanon Army, founded in 1979 the SLA fought against both the PLO and Hezbollah. The SLA was composed of Christians, Shias and Druze from the areas that it controlled but the officers were mostly Christians.
• Guardians of the Cedars, exclusively Maronite with strong anti-Syrian views, 3,000–6,000 uniformed militiamen armed with modern small-arms. They were backed by a mechanized force consisting of a single M50 Super Sherman medium tank, a few M113 armored personnel carriers, M42 Dusters and Chaimite V200[103] armoured cars backed by gun-trucks (Land-Rovers, Toyota Land Cruisers, GMC and Ford light pick-ups, plus US M35A2 2-1/2 ton cargo trucks) fitted with heavy machine guns (HMGs), recoilless rifles, and a few anti-aircraft autocannons.[104]

• The Lebanese National Resistance Front forces totalled about 30,000 fighting men and women. It was the successor of the Lebanese National Movement.
• The Druze were initially neutral but turned against the LF when the new government attempted to force their way into Druze controlled territory in the Chouf region.
  • The People's Liberation Army – PLA (Arabic: Jayish al-Tahrir al-Sha'aby) or Armée de Libération Populaire (ALP), the militia of the Druze Progressive Socialist Party, consisted of 10,000 to 20,000 men and boys.[105]
  • The Al-Mourabitoun (Guardians or Saviours in Arabic) is a primarily Druze (at that time) secular, non-sectarian movement, its membership has always been overwhelmingly Muslim, being perceived within Lebanon as a predominantly Sunni organization. Its militia (Mouqatin or Fighters) numbered several thousand men and were known for wearing red painted Soviet helmets with Mourabitoun painted on front in Arabic script.[92] The Mourabitoun fought alongside the PLO in the Beirut area until the cease fire after which they acquired much cast-off PLO equipment such as tanks and rocket launchers. They were supported largely by Libya and Syria.[92]
• The Kurdistan Workers' Party at the time had training camps in Lebanon, where they received support from the Syrians and the PLO. During the Israeli invasion all PKK units were ordered to fight the Israeli forces. A total of 11 PKK fighters died in the conflict.[8][9][10]

The Christian Lebanese Front, was a coalition of mainly Christian parties formed in 1976, during the Lebanese Civil War. It was intended to act as a counter force to the Lebanese National Movement (LNM) of Kamal Jumblatt and others. Combined Lebanese Front forces totalled about 30,000 fighting men and women. These forces were mostly Phalangist, though there were some men from Saad Haddad's "Free Lebanon forces"[106] and other smaller right-wing militias, including al-Tanzim.

Muslim forces were Shiite organizations:

• Amal Movement is the militia wing of the Movement of the Disinherited, a Shi'a political movement. Initially neutral. The Shia Amal guerrillas had been ordered by their leaders not to fight and to surrender their weapons if necessary.[105]
• Hezbollah is the other Shiite militia ostensibly formed during the invasion around Beirut and backed by Iran.[107]
• Pasdaran – In July 1982 Iran dispatched an expeditionary force of Revolutionary Guards to Lebanon, ostensibly to fight the Israeli invaders. The approximately 650 Pasdaran established their headquarters in the city of Baalbek in the Syrian-controlled Biqa Valley where they conducted guerrilla training, disbursed military matériel and money, and disseminated propaganda.[108]
• The political fission that characterized Lebanese politics also afflicted the Shia movement, as groups split off from Amal. Husayn al Musawi, a former Amal lieutenant, entered into an alliance with the Revolutionary Guard and established Islamic Amal.
• Other Shia groups included Jundallah (Soldiers of God), the Husayn Suicide Commandos, the Dawah (Call) Party, and the notorious Islamic Jihad Organization, reportedly headed by Imad Mughniyyah.[108]

The United Nations Interim Force in Lebanon, or UNIFIL, was created by the United Nations, with the adoption of the United Nations Security Council Resolution 425 and the United Nations Security Council Resolution 426 on 19 March 1978, to confirm Israeli withdrawal from Lebanon which Israel had invaded five days prior, restore international peace and security, and help the Government of Lebanon restore its effective authority in the area. The first UNIFIL troops were deployed in the area on 23 March 1978; these troops were reassigned from other UN peacekeeping operations in the area (namely the United Nations Emergency Force and the United Nations Disengagement Observer Force Zone). During the 1982 Lebanon War, UN positions were overrun, primarily by the South Lebanon Army forces under Saad Haddad.[109]

Numbers of the casualties in the conflict vary widely.[110]

By the end of the first week, 14 June 1982, International Red Cross and Lebanese police figures claimed that 9,583 had died and 16,608 injured. By the end of the second week, they claimed up to 14,000 people died and 20,000 were injured, mostly civilians.[111]

During the Siege of Beirut, by late August 1982, Lebanese sources put the death toll in Beirut at 6,776. This figure included victims of the 4 June 1982, bombing, which occurred two days before the operation officially started. Lebanese police and international doctors serving in Beirut put the number of civilian casualties at about 80%.[112] According to American military analyst Richard Gabriel, all factions in the conflicts agree that between 4,000 and 5,000 civilians died during the siege caused by military activity of all sides. He states that most of the observers that were present on the ground and other relevant sources in Lebanon agree that estimates of 8,000–10,000 are too high.[13]

Accurate numbers of total casualties are hard to estimate, due to "[t]he chaos of warfare, the destruction of city neighborhoods and refugee camps, the haste with which bodies were buried in mass graves and the absence of impartial agencies".[113] Many officials in Beirut, including those of the International Red Cross, claimed that the number of deaths were extremely difficult to estimate correctly. At least one official from a relief organization claimed that in the South about 80% of deaths were civilian and only 20% military.[114]

In early September 1982, the independent Beirut newspaper An Nahar published an estimate of deaths from hospital and police records covering the period from 6 June to 31 August 1982.[114] It claimed that 17,285 people were killed: 5,515 people, both military and civilian, in the Beirut area; and 2,513 civilians, as well as 9,797 military forces, including PLO and Syrians, outside of the Beirut area.[115]

The Lebanese authorities gave a figure of 19,085 killed and 30,000 wounded with combatants accounting for 57% of the dead and civilians 43% in 1982. They do not include the estimated 800–3,500 killed in the Sabra and Shatila massacre.[114]

Richard Gabriel estimated that roughly 2,400 PLO fighters were killed during the war, of whom about 1,400 were killed throughout southern Lebanon and another 1,000 killed during the Siege of Beirut. Gabriel also estimated that between 5,000 and 8,000 civilians died during the war. Some later estimates have put the total figure at 18–19,000 killed and more than 30,000 wounded, most of them civilians. 80% of villages in South Lebanon were damaged, with some completely destroyed.[13][116][117][118][119] The Israeli government maintained that about 1,000 Palestinian fighters and 800 Lebanese civilians died during the invasion, excluding the siege of Beirut.[14][120] Anthony Tucker-Jones wrote that about 1,500 PLO fighters were killed. Kenneth Pollack estimated that 1,200 Syrian soldiers were killed and about 3,000 wounded during the war.[12]

According to Israeli figures, Israeli losses in Operation Peace for Galilee were 368 dead and 2,383 wounded. The highest ranking IDF casualty of the war was brigadier general Yekutiel Adam who was deputy Chief of Staff and appointed head of Mossad. He was killed by a Palestinian fighter while seeking protection in a house in Dawha, near Damour. Other Israeli fatalities included one Colonel; two Lt. Colonels; 19 Majors, 28 Captains; 46 Lieutenants; 132 Sergeants; 90 Corporals; and 49 Privates.[121]

However, IDF losses continued to mount after the war due to guerrilla warfare during the occupation of much of Lebanon. By the time the IDF withdrew to its security zone in southern Lebanon in June 1985, Israel had lost 657 dead and 3,887 wounded.[122] Another three Israeli soldiers who are thought to have fallen into Syrian hands remain officially missing in action to this day. According to Kenneth Pollack, Israeli losses in action against the Syrians were 195 dead and 872 wounded.[12] From the withdrawal to the South Lebanon Security Zone in 1985 to the pullout to the international border in May 2000, the IDF lost another 559 soldiers,[123] including 256 from combat.[124]

Israeli civilian casualties from cross-border shelling numbered 9–10 killed and at least 248 wounded between June 1982 and 1999.[125]

In September 1982, the PLO withdrew most of its forces from Lebanon. With U.S. assistance, Israel and Lebanon reached an accord in May 1983, that set the stage to withdraw Israeli forces from Lebanon while letting them patrol a "security zone" together with the Lebanese Army.

The instruments of ratification were never exchanged, however, and in March 1984, under pressure from Syria, Lebanon cancelled the agreement.

In January 1985, Israel started to withdraw most of its troops, leaving a small residual Israeli force and an Israeli-supported militia, the South Lebanon Army in southern Lebanon in a "security zone", which Israel considered a necessary buffer against attacks on its northern territory. The Israeli withdrawal to the security zone ended in June 1985. Israel withdrew fully from Lebanon in 2000.

The political vacuum resulting from the 1985 Israeli withdrawal would eventually lead to the de facto Syrian occupation of Lebanon. Syria would gain much more power over Lebanon than what it enjoyed before 1982,[24] but it would no longer align with the PLO. In the War of the Camps that followed the Israeli withdrawal, Syria fought their former Palestinian allies.

Following Arafat's decision of June 1982, by September 1982, the PLO had withdrawn most of its forces from Lebanon. Syria backed the anti-Arafat PLO forces of Abu Musa in the Beka valley from May 1983. When Arafat castigated the Syrian government for blocking PLO supplies in June 1983, the Syrian government declared Arafat a persona non-grata on 24 June 1983.[126]

With the withdrawal of the PLO leadership from Tripoli in December 1983 there was an Egyptian-PLO rapprochement, this was found to be encouraging by the Reagan administration but was condemned by the Israeli government.[127]

In the voting in the Knesset on the war, only Hadash opposed the war (and even submitted a no-confidence motion against the Israeli government). Hadash Knesset member Meir Vilner said in the Knesset plenary session that: "The government is leading Israel to an abyss. It is doing something that in the course of time might lead to crying for generations". In response, they were condemned, and calls were heard, among others from the editor of Yediot Ahronoth, to prosecute them for treason. Left-wing Knesset members, including Shulamit Aloni and Yossi Sarid, were absent from the plenary for the vote. Even the Labour faction voted in support. By mid January 1983 Rabin was saying that the Israeli attempt to impose a peace agreement on Lebanon by the use of force was a "mistake" based upon an "illusion".[128]

Heavy Israeli casualties, alleged disinformation of Israeli government leaders and the Israeli public by Israeli military, as well as political advocates of the campaign and lack of clear goals led to increasing disquiet among Israelis. This culminated in a large protest rally in Tel Aviv on 25 September 1982, organized by the Peace Now movement, following the 1982 Sabra and Shatila massacre. Organizers claimed 400,000 people participated in the rally, and it became known as the "400,000 rally". Other estimates put the figure much lower, maybe reaching 100,000 Israelis but including thousands of reserve soldiers back from Lebanon.[129][130]

The Israeli-Maronite alliance dissolved, and Sharon's goal of installing a pro-Israel Christian government in Beirut was not accomplished.[131] 850,000 Christians would emigrate during the Civil War out of Lebanon, most of them permanently.[132]

The withdrawal of the IDF from central Lebanon in the summer of 1983, was followed by one of the bloodiest phases of the Lebanese war, where the Christian Militia (the Lebanese Forces) was left alone to defend the "Mountain" area which comprised the Aley and Chouf districts against a coalition of Druze PSP, PLO remnants, Syrian Army, Lebanese Communist, and Syrian Social National Party. This heavily impacted the civilian population from both sides (more than 5,000 killed from both sides). The Mountain War ended after the Christian forces and civilians withdrew to the town of Deir el Kamar where they were besieged for 3 months before all hostilities ceased and they were transported to East Beirut.

The invasion led to the switching of sides of Amal Movement, which used to fight against the PLO prior to the invasion. The invasion is also popularly held to be the major catalyst for the creation of the Iranian and Syrian supported Hezbollah organization, which by 1991 was the sole armed militia in Lebanon not supported by Israel and by 2000 had completely replaced the vanquished PLO in Southern Lebanon.

According to Abraham Rabinovich, the complete dominance of U.S. and Israeli technology and tactics over those of the Eastern Bloc was to have been a factor that hastened the demise of the Warsaw Pact and Soviet Union.[81][83] However, this was not the first confrontation in which Soviet weaponry had been outmatched by American weaponry. In many of the Cold War conflicts the Americans and their allies had superior technology. Nonetheless, the gap between the First World and Second World weaponry was more apparent in the 1980s and weighed more heavily on Second World leaders.

One of the lingering consequences of the Israeli invasion of Lebanon was the creation of Hezbollah.[133]

In 2000, when Ehud Barak was Israeli Prime Minister, Israel finally withdrew from the security zone to behind the Blue Line. Lebanon and Hezbollah continue to claim a small area called Shebaa Farms as Lebanese territory, but Israel insists that it is captured Syrian territory with the same status as the Golan Heights. The United Nations has not determined the final status of Shebaa Farms but has determined that Israel has complied with UNSC resolution 425. The UN Secretary-General had concluded that, as of 16 June 2000, Israel had withdrawn its forces from Lebanon in accordance with UN Security Council Resolution 425 of 1978, bringing closure to the 1982 invasion as far as the UN was concerned.[134]

Israel's withdrawal from Lebanon led to pressure on the Syrians to withdraw their occupation forces and this pressure intensified after the assassination of the popular Lebanese Prime Minister, Rafik Hariri. On 26 April 2005 the Syrian occupation forces withdrew from Lebanon.[135]

• The invasion removed PLO presence from Southern Lebanon and the Syrian military was weakened by combat losses, especially in the air. However, the removal of the PLO also paved the way for the rise of other militant groups, particularly Hezbollah.
• The failure of the larger Israeli objectives of resolving the conflict in Lebanon with a peace treaty.[136]
• The Lebanese Council for Development and Reconstruction estimated the cost of the damage from the invasion at 7,622,774,000 Lebanese pounds, equivalent to US$2 billion at the time.[137]
• Al-Qaeda leader Osama bin Laden said in a videotape, released on the eve of the 2004 U.S. presidential elections, that he was inspired to attack the buildings of the United States by the 1982 Israeli invasion of Lebanon, in which towers and buildings in Beirut were destroyed in the siege of the capital.[138]
