Summary: U.S.-Libya relations have been strained since the 1960s, culminating in several violent incidents in 1986. After breaking diplomatic ties and facing multiple provocations, including a Libyan missile attack on U.S. Navy aircraft and linked terrorist attacks in Greece and West Berlin, the U.S. launched Operation El Dorado Canyon. This retaliatory strike with F-111 warplanes targeted Libyan terrorist facilities and military barracks using a combined force of U.S. Air Force and Navy aircraft.
