The Front also showed obvious divisions in respect to the First Intifada (1987–91), as well as the Persian Gulf War (1991). In 1991, Palestinian Popular Struggle Front was allowed to rejoin the PLO after accepting United Nations Security Council Resolution 242 and the concept of negotiations with Israel. The Abu Nidal Organization faded continuously into the shadows after 1991, as-Saiqa never grew out of its comfortable niche in the arms of Assad, the ALF did the same under the sponsorship of Saddam Hussein, the DFLP divided in two on the question of the Oslo Accords (1993), while the PFLP began an ambivalent participation in the peace process that never resulted in complete rejection or acceptance.
