In the 1974 Arab League summit held in Morocco on 26 October, a Fatah plot to assassinate Hussein upon his arrival was uncovered by the Moroccan authorities. The plot did not deter Hussein from joining the summit, but at the end Jordan had to join all the Arab countries in recognizing the PLO as "the sole representative of the Palestinian people," a diplomatic defeat for Hussein. The relationship between Jordan and the United States deteriorated when Jordan refused to join the Camp David Accords. The Accords formed the peace treaty between Egypt and Israel, and allowed the withdrawal of Israel from the Sinai. In 1978 Hussein went to Baghdad for the first time since 1958; there, he met Iraqi politician Saddam Hussein. When Saddam became president of Iraq in 1979, Hussein supported Saddam's Iran–Iraq War that stretched from 1980 to 1988. The relationship grew as Saddam provided Jordan with subsidized oil, and Jordan allowed Iraq to use the Port of Aqaba for its exports.
