How did Israel’s 1982 invasion of Lebanon lead to the removal of the Palestine Liberation Organization?

Israel’s 1982 invasion of Lebanon was driven by a desire to dismantle the Palestine Liberation Organization (PLO) and its military infrastructure, which had been conducting cross-border raids into Israel.123

Following the start of the invasion on June 6, 1982, Israeli forces rapidly advanced toward Beirut, eventually encircling the capital and laying siege to the city, where the PLO had established its headquarters. After a period of intense shelling and a dangerous military stalemate, the Israeli government entered into negotiations.142

These negotiations, facilitated by the United States, resulted in an agreement for the PLO to evacuate Beirut under the supervision of a multinational peacekeeping force. This evacuation effectively removed the PLO’s organized military presence from Lebanon, forcing the organization to transfer its headquarters to Tunis, Tunisia.15243
