In 1983 American president Ronald Reagan suggested a peace plan that became known as the Reagan plan, similar to Hussein's 1972 federation plan. Hussein and Arafat both agreed to the plan on 1 April, but the PLO's executive office rejected it. A year and a half later, a renewed effort by Hussein to jumpstart the peace process culminated in the establishment of a Jordan–PLO accord that sought a peaceful resolution to the Israeli-Palestinian conflict, an unprecedented milestone for the PLO and a Jordanian diplomatic victory. The accord was opposed by Israel and garnered no international support from either the United States or the Soviet Union. Around the same time, Hussein met Israel prime minister Shimon Peres on 19 July 1985 in the United Kingdom, where Peres assented to the accord, but later the rest of his government opposed it due to the PLO's involvement. Subsequent talks between the PLO and Jordan collapsed after the PLO refused to make concessions; in a speech Hussein announced that "after two long attempts, I and the government of Jordan hereby announce that we are unable to continue to coordinate politically with the PLO leadership until such time as their word becomes their bond, characterized by commitment, credibility and constancy."
