When the PLO moved to Lebanon from Jordan after 1970, repeated attacks and counter-attacks occurred in southern Lebanon between the PLO and Israel. Two major Israeli incursions into Lebanon occurred in 1978, and the other in 1982, the latter conflict troubled Hussein as the IDF had laid siege to Beirut. The PLO was to be expelled from Lebanon, and Ariel Sharon, the Israeli Defense minister, suggested they be moved to Jordan where the monarchy would be toppled and Jordan would serve as an "alternative Palestinian homeland." Sharon boasted: "One speech by me will make King Hussein realize that the time has come to pack his bags." However, Arafat rejected Sharon's suggestion, and the fedayeen were transported to Tunisia under American cover.
