The Six-Day war began when Israel launched air strikes against Egypt's air force on 5 June 1967. The war ended in an Arab defeat and Israel's occupation of several Arab territories, including the West Bank and Gaza Strip. Although Nasser and his Arab allies had been defeated, Arafat and Fatah could claim a victory, in that the majority of Palestinians, who had up to that time tended to align and sympathize with individual Arab governments, now began to agree that a 'Palestinian' solution to their dilemma was indispensable. Many primarily Palestinian political parties, including George Habash's Arab Nationalist Movement, Hajj Amin al-Husseini's Arab Higher Committee, the Islamic Liberation Front and several Syrian-backed groups, virtually crumbled after their sponsor governments' defeat. Barely a week after the defeat, Arafat crossed the Jordan River in disguise and entered the West Bank, where he set up recruitment centers in Hebron, the Jerusalem area and Nablus, and began attracting both fighters and financiers for his cause.
