As in other areas of Asia, the end of World Was II led to the emergence of a number of independent states. Jordan, Lebanon, and Syria, all European mandates before the war, became independent. Egypt, Iran, and Iraq, though still under a degree of Western influence, became increasingly autonomous. Sympathy for the idea of Arab unity led to the formation of the Arab League in 1945, but different points of view among its members prevented it from achieving anything of substance. The one issue on which all Arab states in the area could agree was the question of Palestine. As tensions between Jews and Arabs in that mandate intensified during the 1930s, the British attempted to limit Jewish immigration into the area and firmly rejected proposals for independence. After World War II, the Zionists turned for support to the United States, and in March 1948, the Truman administration approved the concept of an inde- pendent Jewish state, despite the fact that only about one-third of the local population were Jews. In May, the new state of Israel was formally established. To its Arab neighbors, the new state represented a betrayal of the interests of the Palestinian people, 90 percent of whom were Muslim, and a flagrant disregard for the conditions set out in the Balfour Declaration of 1917. Outraged at the lack ofWestern support for Muslim interests in the area, several Arab countries invaded the new Jewish state. The invasion did not succeed because of internal divisions among the Arabs, but both sides remained bitter, and the Arab states refused to recognize Israel. The war had other lasting consequences as well because it led to the exodus of thousands of Palestinian refugees into neighboring Muslim states. Jordan, which had become independent under its Hashemite ruler, was now flooded by the arrival of one million urban Palestinians in a country occupied by half a million Bedouins. To the north, the state of Lebanon had been created to provide the local Christian community with a country of its own, but the arrival of the Palestinian refugees upset the delicate balance between Christians and Muslims. In any event, the creation of Lebanon had angered the Syrians, who had lost it as well as other territories to Turkey as a result of European decisions before and after the war.
