British, Arab, and Jewish reactions to the recommendations were not favorable. Jewish terrorism in Palestine antagonized the British, and by February 1947 Arab-Jewish communications had collapsed. Britain, anxious to rid itself of the problem, set the United Nations in motion, formally requesting on April 2, 1947, that the U.N. General Assembly set up the Special Committee on Palestine (UNSCOP). This committee recommended that the British mandate over Palestine be ended and that the territory be partitioned into two states. Jewish reaction was mixed -- some wanted control of all of Palestine; others realized that partition spelled hope for their dream of a homeland. The Arabs were not at all agreeable to the UNSCOP plan. In October the Arab League Council directed the governments of its member states to move troops to the Palestine border. Meanwhile, President Truman instructed the State Department to support the U.N. plan, and, reluctantly, it did so. On November 29, 1947, the partition plan was passed in the U.N. General Assembly.
UN Resolution 181, defined the outline of a settlement in Palestine creating both a Jewish and a Palestinian homeland. The 1947 UN Partition divided the area into three entities: a Jewish state, an Arab state, and an international zone around Jerusalem.
At midnight on May 14, 1948, the Provisional Government of Israel proclaimed the new State of Israel. On that same date the United States, in the person of President Truman, recognized the provisional Jewish government as de facto authority of the new Jewish state (de jure recognition was extended on January 31). The U.S. delegates to the U.N. and top ranking State Department officials were angered that Truman released his recognition statement to the press without notifying them first. On May 15, 1948, the Arab states issued their response statement and Arab armies invaded Israel and the first Arab-Israeli war began.
