In a speech to the Jordanian parliament on 15 March 1972, Hussein announced his "United Arab Kingdom" plan. Unlike the unitary state that had existed between the West Bank and Jordan during Jordan's annexation of the West Bank (1950–1967), this plan envisaged two federal entities on each bank of the Jordan River. According to the proposal, the two districts of the federation would be autonomous, excluding the military and the foreign and security affairs that would be determined by an Amman central government. But the implementation of the plan was to be conditional upon achieving a peace agreement between Israel and Jordan. Ultimately, Hussein's proposal was ruled out after it was vehemently rejected by Israel, the PLO, and several Arab states.
