South Lebanon conflict (1982–2000)

The South Lebanon conflict (1982–2000) or the Security Zone conflict in Lebanon refers to nearly 20 years of warfare between the Israel Defense Forces and its Lebanese proxy militias and Lebanese Muslim guerrillas led by the Iranian-backed Hezbollah within what was defined by Israelis as the "Security Zone" in South Lebanon. It can also refer to the continuation of conflict in this region, beginning with PLO operations transfer to South Lebanon, following the civil war events of 1971 Black September in the Kingdom of Jordan. Historical tension between Palestinian refugee and Lebanese factions fomented the violent Lebanese internal political struggle between many different factions. In light of this, the South Lebanon conflict can be seen as a part of the Lebanese Civil War.

Earlier conflicts prior to 1982 Israeli invasion, including Operation Litani attempted to eradicate the PLO bases from Lebanon and support Christian Maronite militias, following PLO's constant attacks on civilian population of Galilee (Northern Israel). The 1982 invasion resulted in the Palestine Liberation Organization's (PLO) departure from Lebanon. The creation of Security Zone in South Lebanon has benefited civilian Israeli population as Galilee suffered less violent attacks by Hezbollah (44 Israeli civilian casualties), than previously by PLO in the 1970s (hundreds of Israeli civilian casualties). Despite this Israeli success in eradicating PLO bases and partial withdraw in 1985, the Israeli invasion had actually increased the severity of conflict with local Lebanese militias and resulted in the consolidation of several local Shia Muslim movements in Lebanon, including Hezbollah and Amal, from a previously unorganized guerrilla movement in the south. Over the years, military casualties of both sides grew higher, as both parties used more modern weaponry, and Hezbollah progressed in its tactics. By the early 1990s, Hezbollah, with support from Syria and Iran, emerged as the leading group and military power, monopolizing the directorship of the guerrilla activity in South Lebanon.

By the year 2000, following his campaign promise, newly elected Prime Minister Ehud Barak withdrew Israeli forces from Southern Lebanon within the year, in accordance with UN Security Council Resolution 425, passed in 1978; the withdrawal consequently resulted in the immediate total collapse of the SLA. Despite the Israeli actions, Lebanese government and Hezbollah consider the withdrawal incomplete until Israel withdraws from Shebaa Farms. Following the withdrawal, Hezbollah has monopolized its military and civil control of the southern part of Lebanon.

Background
Following the 1948 Arab Israeli War, the 1949 Armistice Agreements were signed with United Nations mediation. The Lebanese-Israeli agreement created the armistice line, which coincided exactly with the existing international boundary between Lebanon and Palestine from the Mediterranean to the Syrian tri-point on the Hasbani River. From this tri-point on the Hasbani the boundary follows the river northward to the village of Ghajar, then northeast, forming the Lebanese-Syrian border. (The southern line from the tri-point represents the Palestine-Syria border of 1923.) Israeli forces captured and occupied 13 villages in Lebanese territory during the conflict, including parts of Marjayun, Bint Jubayl, and areas near the Litani River, but withdrew following international pressure and the armistice agreement.

Although the Israel-Lebanon border remained relatively quiet, entries in the diary of Moshe Sharett point to a continued territorial interest in the area. On 16 May 1954, during a joint meeting of senior officials of the defense and foreign affairs ministries, Ben Gurion raised the issue of Lebanon due to renewed tensions between Syria and Iraq, and internal trouble in Syria. Dayan expressed his enthusiastic support for entering Lebanon, occupying the necessary territory and creating a Christian regime that would ally itself with Israel. The issue was raised again in discussions at the Protocol of Sèvres.

The Israeli victory in the 1967 Six Day War vastly expanded their area occupied in all neighboring countries, with the exception of Lebanon, but this extended the length of the effective Lebanon-Israel border, with the occupation of the Golan Heights. Although with a stated requirement for defense, later Israeli expansion into Lebanon under very similar terms followed the 1977 elections, which for the first time, brought the more militant, expansionist and Revisionist Likud to power.

Emerging Conflict between Israel and Palestinian militants
Beginning with late 1960s and especially in 1970s, following the defeat of PLO in Black September in Jordan, displaced Palestinians, including militants affiliated with the Palestinian Liberation Organization, began to settle in South Lebanon. The unrestrained buildup of Palestinian militia, and the large autonomy they exercised, led to the popular term "Fatahland" for South Lebanon. Since mid 1970s the tensions between the various Lebanese factions and Palestinians had exploded, resulting in Lebanese Civil War.

Following multiple terrorist attacks launched by Palestinian organizations in the 1970, which increased with the Lebanese Civil War, the Israeli government decided to take action. Desiring to break up and destroy this PLO stronghold, Israel briefly invaded Lebanon in 1978, but the results of this invasion were mixed. The PLO was pushed north of the Litani River and a buffer zone was created to keep them from returning, with the placement of the United Nations Interim Force in Lebanon (UNIFIL). In addition and despite earlier covert support, Israel established a second buffer with renegade Saad Haddad’s Christian Free Lebanon Army enclave (initially based only in the towns of Marjayoun and Qlayaa); the now-public Israeli military commitment to the Christian forces was strengthened. For the first time however, Israel received substantive adverse publicity in the world press due to damage in South Lebanon, in which some 200,000 Lebanese (mostly Shia Muslims) fled the area and ended up in the southern suburbs of Beirut; this indirectly resulted in the Syrian forces in Lebanon turning against the Christians in late June and complicated the dynamics of the on-going Lebanese Civil War.

Israeli Invasion
In 1982, the Israeli military began "Operation Peace for Galilee", a full scale invasion of Lebanese territory. The invasion followed the 1978 Litani Operation, which gave Israel possession of the territory near the Israeli-Lebanese border. This follow-up invasion attempted to weaken the PLO as a unified political and military force and eventually led to the withdrawal of PLO and Syrian forces from Lebanon. By the end of this operation, Israel got control over Lebanon from Beirut southward, and attempted to install a pro-Israeli government in Beirut to sign a peace accord with it. This goal had never realized, partly because of the assassination of President Bashir Gemayel in September 1982, and the refusal of the Lebanese Parliament to endorse the accord. The withdrawal of the PLO forces in 1982 forced some Lebanese nationalists to start a resistance against the Israeli army led by the Lebanese Communist Party and Amal movement. During this time, some Amal members started the formation of an Islamic group supported by Iran that was the nucleus of the future "Islamic Resistance", and eventually become Hezbollah.

Occupation period 1982–1985 – the emergence of Hizbullah
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. In October, the United States Marines barracks in Beirut was bombed (usually attributed to the Islamic Resistance groups). Following this incident, the United States withdrew its military forces from Lebanon.

Suicide bombings became increasingly popular at this time, and were a major concern of the Israel Defense Forces (IDF) both near Beirut and in the South. Among the most serious were the two suicide bombings against the Israeli headquarters in Tyre, which killed 103 soldiers, border policemen, and Shin Bet agents, and also killed 49–56 Lebanese. Israel believes those acts were among the first organized actions made by Shi'ite militants, later forming into Hizbullah. Subsequently, Israel withdrew from the Shouf Mountains, but continued to occupy Lebanon south of the Awali River.

An increased number of Islamic militias began operating in South Lebanon, launching guerilla attacks on Israeli and pro-Israel militia positions. Israeli forces often responded with increased security measures and airstrikes on militant positions, and casualties on all sides steadily climbed. In a vacuum left with eradication of PLO, the disorganized Islamic militants in South Lebanon began to consolidate. The emerging Hezbollah, soon to become the preeminent Islamic militia, evolved during this period. However, scholars disagree as to when Hezbollah came to be regarded as a distinct entity. Over time, a number of Shi’a group members were slowly assimilated into the organization, such as Islamic Jihad members, Organization of the Oppressed on Earth, and the Revolutionary Justice Organization.

Israeli withdrawal to Security Zone
In February 1985, Israel withdrew from Sidon and turned it over to the Lebanese Army, but faced attacks: 15 Israelis were killed and 105 wounded during the withdrawal. Dozens of SLA members were also assassinated. From mid-February to mid-March, the Israelis lost 18 dead and 35 wounded. On 11 March, Israeli forces raided the town of Zrariyah, killing 40 Amal fighters and capturing a large stock of arms. On 9 April, a Shiite girl drove a car bomb into an IDF convoy, and the following day, a soldier was killed by a land mine. During that same period, Israeli forces killed 80 Lebanese guerrillas in five weeks. Another 1,800 Shi'as were taken as prisoners. Israel withdrew from the Bekaa valley on 24 April, and from Tyre on the 29th, but continued to occupy a security zone in Southern Lebanon.

In 1985 Hezbollah released an open letter to "The Downtrodden in Lebanon and in the World", which stated that the world was divided between the oppressed and the oppressors. The oppressors were named to be mainly the United States and Israel. This letter legitimized and praised the use of violence against the enemies of Islam, mainly the West. The newfound unity among these Shi'a resistance groups in 1985 has been credited to the disappearance of Musa al-Sadr. Fighting the Israeli occupation included hit-and-run guerrilla attacks, suicide bombings, and the Katyusha rocket attacks on civilian targets in Northern Israel, including Kiryat Shmona. The Katyusha proved to be an effective weapon and became a mainstay of the resistance in South Lebanon. The attacks resulted in both military and civilian casualties. However, a considerable number of Lebanese guerillas were killed fighting Israeli and SLA troops, and many were captured. Prisoners were often detained in Israeli military prisons, or by the SLA in the infamous Khiam detention center, where detainees were often tortured. Lebanese prisoners in Israel were arrested and detained for participating in guerilla movements, and many were held for long periods of time.

In 1987 Hizbullah fighters from the Islamic Resistance stormed and conquered an outpost i Bra’shit belonging to the South Lebanon Army in the security zone. A number of its defenders were killed or taken prisoner and the Hizbullah flag was raised on top of it. A Sherman tank was blown up and a M113 Armored Personal Carrier was captured and driven triumphantly all the way to Beirut.

After Israel destroyed Hezbollah's headquarters in the town of Marrakeh, a Hezbollah suicide bomber destroyed an Israeli transport truck carrying soldiers on the Israel-Lebanon border. In response, Israeli forces ambushed two Hezbollah vehicles, killing eight Hezbollah fighters.

On 28 July 1989, Israeli commandos captured Sheikh Abdul Karim Obeid, the leader of Hezbollah. This action led to the adoption of United Nations Security Council Resolution 638, which condemned all hostage takings by all sides.

Taif Accord
The Lebanese Civil War officially came to an end with the 1989 Ta'if Accord, but the armed combat continued at least until October 1990, and in South Lebanon until at least 1991. In fact, the continued Israeli presence in South Lebanon resulted in continued low-intensity warfare and sporadic major combat until the Israeli withdrawal in 2000.

Post Civil War conflict
Though the majority of the Lebanese civil war conflicts ended in the months following the Ta'if Accord, Israel kept maintaining a military presence in South Lebanon. Consequently, the Islamic Resistance, by now dominated by Hezbollah, continued operations in the South. On 16 February 1992, Hezbollah leader Abbas al-Musawi was killed along with his wife, son and four others when Israeli AH-64 Apache helicopter gunships fired three missiles at his motorcade. The Israeli attack came in retaliation for the killings of three Israeli soldiers two days earlier when their camp was infiltrated. Hezbollah responded with rocket fire onto the Israeli security zone, and Israel then fired back and sent two armored columns past the security zone to hit Hezbollah strongholds in Kafra and Yater. Musawi was succeeded by Hassan Nasrallah. One of Nasrallah's first public declarations was the "retribution" policy: If Israel hit Lebanese civilian targets, then Hezbollah would retaliate with attacks on Israeli territory. Meanwhile, Hezbollah continued attacks against IDF targets within occupied Lebanese territory.

In 1993, hostilities flared again. After a month of Hezbollah shelling on Israeli towns and attacks on its soldiers, Israel conducted a seven-day operation called Operation Accountability in order to hit Hezbollah. One Israeli soldier and 8–50 Hezbollah fighters were killed in the operation, along with 2 Israeli and 118 Lebanese civilians. After one week of fighting in South Lebanon, a mutual agreement mediated by the United States prohibited attacks on civilian targets by both parts. However, Hezbollah soon resumed attacks on Israeli military positions and its proxy, the SLA.

In May 1994, Israeli commandos kidnapped an Amal leader Mustafa Dirani, and in June, an Israeli airstrike against a training camp killed 30–45 Hezbollah cadets. Hezbollah retaliated by firing four barrages of Katyusha rockets into northern Israel.

Continued hostility in late 1990s
Operation Grapes of Wrath resulted in the deaths of more than 150 civilians and refugees, most of them in the shelling of a United Nations base at Qana. Within a few days, a ceasefire was agreed between Israel and Hezbollah, committing to avoid civilian casualties; however, combat continued for at least two months. A total of 14 Hezbollah fighters, 1 Syrian soldier, and 3 Israeli soldiers were killed in the fighting. Brig. Gen. Eli Amitai, the IDF commander of the security zone, was lightly injured December 14, 1996 when an IDF convoy he was travelling in was ambushed in the eastern sector of the security zone. Less than a week later Amitai was again lightly injured when Hezbollah unleashed a mortar barrage on an SLA position near Bra'shit he was visiting together with Maj. Gen. Amiram Levine, head of the IDF's Northern Command.

On 4 February 1997, two Israeli transport helicopters collided over She'ar Yashuv in Northern Israel while waiting for clearance to fly into Lebanon. A total of 73 IDF soldiers were killed in the disaster. On 28 February one Israeli soldier and four Hezbollah guerrillas were killed in a bloody clash. On 4 August 1997, Israeli soldiers killed five Hezbollah gunmen, including two area commanders, in a clash north of the security zone.

On 5 September 1997, a raid by 16 Israeli Shayetet 13 naval commandos failed after the troops stumbled into an IED ambush, killing 12, including the units commander, Lt.-Col. Yossi Korakin. Most of the killed and wounded commandos could later be extracted in a difficult rescue operation. The body of one soldier, Itamar Ilyah, was left behind.

In 2010 Hassan Nasrallah revealed that Hizbullah had managed to hack into Israeli UAV:s flying over Lebanon and thus learn which route the commandos were planning to take and thus prepared the ambush accordingly.

Shortly afterward, Hizbullah fighter Hadi Nasrallah was killed in a clash with Israeli soldiers. Hadi was the son of Hezbollah leader Hassan Nasrallah, and his body was captured by IDF. On May 25, 1998 the remains of the dead IDF soldier was exchanged for 65 Lebanese prisoners and the bodies of 40 Hezbollah fighters and Lebanese soldiers captured by Israel. Among the bodies returned to Lebanon were the remains of Hadi Nasrallah.

On 2 December 1998 Israeli army killed Zahi Naim Hadr Ahmed Mahabi, a top Hezbollah explosives expert. During 1998 21 Israeli soldiers were killed in southern Lebanon.

During 1999, several dozen Hezbollah and Amal fighters were killed. Twelve Israeli soldiers and one civilian were also killed, one of them in accident.

February 23 1999 an IDF paratrooper unit on a night time patrol was ambushed in south Lebanon. Major Eitan Balahsan and two lieutenants were killed and another five soldiers wounded.

Less than a week later (February 28) a roadside bomb exploded on the road between Kawkaba and Arnoun in the Israeli-occupied Security zone. Brigadier General Erez Gerstein, commander of the Golani Division and head of the IDF Liaison Unit in Lebanon, thus the highest ranking Israeli officer serving in Lebanon at the time, as well as two Israeli soldiers and one Israeli journalist were killed in the blast.

In May 1999 Hizbullah forces simultaneously attacked 14 Israeli and SLA outposts in south Lebanon. The outpost in Beit Yahoun compound belonging to the SLA was overrun and one SLA soldier was taken prisoner. The Hizbullah fighters made off with an Armoured Personnel Carrier (APC). The area was bombed by the Israeli air force. The captured APC was paraded through the southern suburbs of Beirut.

In August 1999 Hezbollah leader Ali Hassan Deeb, better known as Abu Hassan, was allegedly killed by an Israeli intelligence network in Lebanon.

In early 2000, Chief-of-Staff Shaul Mofaz said that 1999 was "the IDF's most successful year in Lebanon". 11 soldiers were killed by hostiles in Southern Lebanon in 1999, the lowest casualty rate during the entire low-intensity conflict. Hezbollah and Amal casualties are unknown, but estimates run into several dozens.

2000: Israeli withdrawal
In July 1999, Ehud Barak became Israel's Prime Minister, promising Israel would unilaterally withdraw to the international border by July 2000. Prior to his actions, many believed that Israel would only withdraw from South Lebanon upon reaching an agreement with Syria.

In January 2000, Hezbollah assassinated the commander of the South Lebanon Army's Western Brigade, Colonel Aql Hashem, at his home in the security zone. Hashem had been responsible for day to day operations of the SLA. After this assassination there were doubts about the leadership of the South Lebanon Army (SLA). The pursuit and assassination of Hashim was documented step by step and the footage was broadcast on Hezbollah TV channel al-Manar. The operation and the way it was presented in media dealt a devastating blow to the morale in the SLA.

During the spring of 2000, Hezbollah operations stepped up considerably, with persistent harassment of Israeli military outposts in occupied Lebanese territory. As preparation for the major withdrawal plan, Israeli forces began abandoning several forward positions within the security zone of South Lebanon. On 24 May, Israel announced that it would withdraw all troops from South Lebanon. All Israeli forces had withdrawn from Lebanon by the end of the next day, more than six weeks before its stated deadline of 7 July.

The Israeli pullout resulted in the collapse of the SLA and the rapid advance of Hezbollah forces into the area. As the Israeli Defense Forces (IDF) withdrew, thousands of Shi'a Lebanese rushed back to the South to reclaim their properties. This withdrawal was widely considered a victory for Hezbollah and boosted its popularity in Lebanon. The completeness of the withdrawal is still disputed as Lebanese Government and Hizbollah claim Israel still holds Shebaa farms, a small piece of territory on the Lebanon-Israel-Syria border, with disputed sovereignty.

As a Syrian-backed Lebanese government refused to demarcate its border with Israel, Israel worked with UN cartographers led by regional coordinator Terje Rød-Larsen to certify Israel had withdrawn from all occupied Lebanese territory. On 16 June 2000, UN Security Council concluded that Israel had indeed withdrawn its forces from all of Lebanon, in accordance with United Nations Security Council Resolution 425 (1978).

Israel considered this move as tactical withdrawal since it always regarded the Security Zone as a buffer zone to defend Israel's citizens. By ending the occupation, Barak's cabinet assumed it would improve its worldwide image. Ehud Barak has argued that "Hezbollah would have enjoyed international legitimacy in their struggle against a foreign occupier", if the Israelis had not unilaterally withdrew without a peace agreement.

Aftermath
Upon Israel's withdrawal, an increasing fear that Hezbollah would seek vengeance against those thought to have supported Israel became widespread among the Christian Lebanese of the Southern Lebanon. During and after the withdrawal around 10,000 Lebanese, mostly Maronites, fled into Galilee. Hezbollah later met with Lebanese Christian clerics to reassure them that the Israeli withdrawal was a victory for Lebanon as a nation, not just one sect or militia.

The tentative peace, resulting from the withdrawal, did not last. On 7 October 2000 Hezbollah attacked Israel. In a cross-border raid, three Israeli soldiers, who were patrolling the Lebanese border were attacked and abducted. The event escalated into a 2 month fire exchanges between Israel and Hezbollah, primarily at the Hermon ridge. The bodies of the abducted soldiers were returned to Israel in a January 2004 prisoner exchange involving 450 Lebanese prisoners held in Israeli jails. The long-time Lebanese prisoner Samir al-Quntar was excluded from the deal. The government of Israel, however, had agreed to a "further arrangement", whereby Israel would release Samir al-Quntar if it was supplied with "tangible information on the fate of captive navigator Ron Arad".

According to Harel and Issacharoff the second phase of the prisoner exchange deal was only a "legal gimmick". Israel was not satisfied with the information supplied by Hezbollah and refused to release al-Quntar. "Cynics may well ask whether it was worth getting entangled in the Second Lebanon War just to keep Kuntar […] in prison for an extra few years."

In July 2006, Hezbollah performed a cross-border raid while shelling Israeli towns and villages. During the raid Hizbullah succeeded in kidnapping two Israeli soldiers and killing eight others. In retaliation Israel began the 2006 Lebanon War to rescue the abducted soldiers and to create a bufferzone in Southern Lebanon.
