By 1939 ..."the Jewish settlement strengthened and deepened its roots in Palestine, anxiety mounted among the Palestinian Arabs, resulting in violent clashes between the two communities. In 1939 Britain changed its Middle East policy, abandoning its sympathetic stand toward the Jews and adopting a sympathetic attitude toward the Arabs, leading to severe restrictions on Jewish immigration and settlement in Palestine.
Ben-Gurion reacted by calling upon the Jewish community to rise against England, thus heralding the decade of “fighting Zionism.”¹ On May 12, 1942, he assembled an emergency conference of American Zionists in New York City; the convention decided upon the establishment of a Jewish commonwealth in Palestine after the war. At the end of World War II, Ben-Gurion again led the Jewish community in its successful struggle against the British mandate"
