Israeli occupation of southern Lebanon (1978-2000)
Israel occupied a self-declared 'security zone' in southern Lebanon for 22 years, backing a proxy militia. In May 2000, Prime Minister Ehud Barak withdrew all Israeli forces after Hezbollah's guerrilla campaign made the occupation costly.
Hezbollah claimed victory for forcing the withdrawal, which became central to its legitimacy in Lebanon.
The withdrawal created a power vacuum Hezbollah filled, turning southern Lebanon into a launchpad for future attacks on Israel.
Israel again maintains a security buffer zone inside Lebanon today, and the June framework ties withdrawal to Hezbollah's disarmament. The 2000 precedent shows what happens when Israel leaves without a parallel disarming of Hezbollah - the group's power grew.
