Why did Israel maintain a security buffer in Southern Lebanon for fifteen long years?

In short: From 1985 to 2000, Israel occupied a strip of Southern Lebanon to shield its northern border from militant attacks. This Security Zone, managed by a local Christian militia, became the site of a persistent, low-intensity guerrilla war that ultimately reshaped the region's political landscape and forced a sudden, chaotic withdrawal.

The Security Zone emerged from the aftermath of the Lebanese Civil War and Israel's 1982 invasion. By 1985, Israel had retreated to a buffer strip covering roughly 800 square kilometres, home to about 180,000 residents. While the Israel Defense Forces provided logistical and military oversight, the day-to-day administration and security fell to the South Lebanon Army, a Christian militia led by Antoine Lahad. This arrangement was supported by the Good Fence policy, which allowed Lebanese citizens to work in Israel and access medical services, such as ophthalmology care at the Western Galilee Hospital.

The occupation was defined by a grinding conflict against Hezbollah and other militant groups. Israel attempted various strategies to curb these threats, including targeted assassinations, such as the 1992 killing of Hezbollah leader Abbas Musawi, and large-scale military campaigns like Operation Accountability in 1993 and Operation Grapes of Wrath in 1996. Despite these efforts, the security situation remained volatile. Israeli soldiers, who were not initially issued service ribbons because the government classified the deployment as a low-intensity conflict rather than a war, faced constant danger from roadside attacks and assaults on military camps.

By the late 1990s, the situation became unsustainable. Prime Minister Ehud Barak pledged a full withdrawal, which triggered the rapid collapse of the South Lebanon Army. As desertion rates soared, the administration disintegrated, leading to a mass exodus of thousands of refugees into Israel. On 24 May 2000, the final Israeli forces withdrew to the internationally recognized border. It was not until 2020 that Israel officially recognized the period as a war, retroactively naming it the Security Zone in Lebanon Campaign, acknowledging the 256 soldiers who died during those fifteen years of occupation.
