I'm unconvinced that FDR deliberately caused the deaths of thousands of americans and allies by provoking an attack on Pearl Harbot. Your site shows memos which indicate that such an attack would make for a great excuse for entering the war, but fail in many ways. First off, the Japanese could just has easily attacked the Presidio in San Francisco. Or Alameda, or San Diego, or the Aleutians.
They could also have just as easily limited their attack to the Philipines.
The Summer 1941 embargo of Japn, which resulted from the breakdown in negotiations certainly did not happen in a vacuum. US leaders undoubtedly understood that there was no dealing with hitler and that since Japan was hitler's ally, if they wanted to help Britain further, they would have to go to war. Hitler did them a favor by attacking the USSR (bringing them into the war on our side). Japan's attack on Pearl had the effect of bringing the US in. Even if the attack had not been such a surprise, like if the incoming flight of zeros had not been mistaken for a returning flight of patrol planes or some-such, the Effect of Japan attacking Pearl without declaring war first is what caused the outrage.
But the outrage was unnecessary. the US didn't need it to crush the Japanese. indeed, it was production, not emotion, which won the war in the pacific. that and advanced training techniques. by the end of 1944, the US were running around in new carriers, new planes, with new pilots who knew what they were doing. The Japanese were still in Zeros (and the like) and running low on ships, oil to run the ships, fuel for the planes, and qualified pilots to fly them. Defeat was inevitable.
Never say you know a man until you have divided an inheritance with him.
