Let me make it clear first. Pearl Harbor was a surprise attack, and the US government under FDR had sbsolutely no foreknowlege of what was going to happen. Conspiracy theorists please get out of this thread. However, in 1944, Governor Dewey initially planned to accuse President Roosevelt of Pearl Harbour foreknowledge, but was persuaded by the military not to do so. What if Dewey really made such an accusation on the campaign trail? What would happen next? Backfire with a bigger landslide for Roosevelt, or the demoralization of the war and Dewey's victory?
