Volume XV of the Letters of Chaim Weizmann opens with the Zionist leader in an ambiguous situation: although he has resigned the Presidency of the Zionist Organization and Jewish Agency in protest against the Passfield White Paper of October 1930, which restricted Jewish immigration into Palestine and the acquisition of land there, no successor has been selected. Weizmann in fact is still the head of the movement, and this situation continues until he finds himself formally replaced as President by Nahum Sokolow at the Seventeenth Zionist Congress the following year.
