The significance of the Program to a Jewish Commonwealth was in stepping beyond the terms of the Balfour Declaration (which had been reaffirmed as British policy by Winston Churchill's White Paper of 1922) that there should be a "Jewish National Home" in Palestine. According to Ami Isseroff, the Program was "a crucial step in the development of the Zionist movement, which increasingly saw itself as opposed to Britain rather than a collaborator of Britain, and it determined that henceforth Ben-Gurion and the Zionist Executive in Palestine, rather than Weizmann would lead the Zionist movement and determine policy toward the British."[1]
