On April 6, 1972, the Egyptian government severed relations in protest for a Jordanian plan for federation with the West Bank, which did not take PLO interests into consideration. These relations were restored on September 11, 1973. They were severed again in 1979, this time by the Jordanian government, in protest for the Israeli-Egyptian peace treaty. Following the outbreak of the Lebanon War of 1982, the US government put pressure on both governments to reach accommodation for the purpose of formulating a joint peace strategy vis-a-vis the Israeli government, and relations were restored on September 25, 1984.
