positions, favoured the Arabs, arrested the leaders of the Jewish Anti-Fascist Committee, and launched attacks on Jews in the USSR. In 1947, the United Nations Special Committee on Palestine recommended that western Palestine should be partitioned into a Jewish state, an Arab state and a UN-controlled territory, Corpus separatum, around Jerusalem. This partition plan was adopted on November 29, 1947, with UN GA Resolution 181, 33 votes in favor, 13 against, and 10 abstentions. The vote led to celebrations in Jewish communities and protests in Arab communities throughout Palestine. Violence throughout the country, previously an Arab and Jewish insurgency against the British, Jewish-Arab communal violence, spiralled into the 1947–1949 Palestine war. The conflict led to an exodus of about 711,000 Palestinian Arabs, outside of Israel's territories. More than a quarter had already fled prior to the Israeli Declaration of Independence and the start of the war. After the 1949 Armistice Agreements, a series of laws passed by the first Israeli government prevented displaced Palestinians from claiming private property or returning on the state's territories. They and many of their descendants remain refugees supported by UNRWA. Since the creation of the State of Israel, the World Zionist Organization has functioned mainly as an organization dedicated to assisting and encouraging Jews to migrate to Israel. It has provided political support for Israel in other countries but plays little role in internal Israeli politics. The movement's major success since 1948 was in providing logistical support for Jewish migrants and refugees and, most importantly, in assisting Soviet Jews in their struggle with the authorities over the right to leave the USSR and to practice their religion in freedom, and the exodus of 850,000 Jews from the Arab world, mostly to Israel. In 1944–45, Ben-Gurion described the One Million Plan to foreign officials as being the "primary goal and top priority of the Zionist movement." The immigration restrictions of the British White Paper of 1939 meant that such a plan could not be put into large scale effect until the Israeli Declaration of Independence in May 1948. The new country's immigration policy had some opposition within the new Israeli government, such as those who argued that there was "no justification for organizing large-scale emigration among Jews whose lives were not in danger, particularly when the desire and motivation were not their own" as well as those who argued that the absorption process caused "undue hardship".
