Just before the end of his term in 1982, Israel invaded southern Lebanon in the 1982 Lebanon War and had advanced to the outskirts of Beirut. He organized a peacekeeping force involving U.S., British, French and Italian troops in Beirut after the Israeli invasion of Lebanon to drive out the Palestine Liberation Organization in 1982. In addition, Sarkis formed the rescue committee in 1982 to make arrangements regarding the results of the Israeli invasion. The members of the committee included the Amal movement’s leader, Nabih Berri, and the hardline Christian leader Bashir Gemayel. The body was significant in that it caused tensions in the Amal movement, because Hussein Musawi left the Amal protesting against Berri and founded Islamic Amal after this event.
