In his six volume history, The Second World War, Sir Winston Churchill never once mentioned the Holocaust against the Jews. Nothing about gas chambers, not a word about genocide.Yet we know that Europe's Jewish leaders provided Churchill with substantial materials on the war against them. After the war ended, Chaim Weizmann wrote to Churchill asking why he had been silent on the matter. He had no reply.What should we conclude from this fact? That Churchill did nothing to help Europe's Jews?That conclusion would be, prima facie, frivolous.Likewise are Cornwell's conclusions about Pope Piux XII.
