27 December 1945: Played golf today with Joe Kennedy [Joseph P. Kennedy, who was Roosevelt’s Ambassador to Great Britain in the years immediately before the war]. I asked him about his conversations with Roosevelt and Neville Chamberlain from 1938 on. He said Chamberlain’s position in 1938 was that England had nothing with which to fight and that she could not risk going to war with Hitler. Kennedy’s view: That Hitler would have fought Russia without any later conflict with England if it had not been for Bullitt’s [William C. Bullitt (Jewish), then Ambassador to France] urging on Roosevelt in the summer of 1939 that the Germans must be faced down about Poland; neither the French nor the British would have made Poland a case of war if it had not been for the constant needling from Washington. Bullitt, he said, kept telling Roosevelt that the Germans wouldn’t fight, Kennedy that they would, and that they would overrun Europe. Chamberlain, he says, stated that America and the world Jews had forced England into the war.
