It's true that FDR and his comrades were advocating for war long before Pearl Harbor. I believe "The Warhawks" by Mark Lincoln Chadwin is a good source on this topic.
But "Pearl Harbor was provoked/foreseen by FDR" is a canard, it's been disproven many times over. It's WW2's version of 9/11 truthism, basically.
FDR had been Secretary of the Navy and respected the Navy -- to the degree the U.S. Army had to remind him it, too, existed.
A lot of conspiracy theories have erupted trying to prove FDR/the U.S. govt. knew the Japanese were going to bomb Pearl Harbor. There's a lot of reason to believe that there were intelligence screw-ups, and that the typical dot gov bureaucrats had their heads up their posteriors, but there is no smoking gun showing there was any vile plotting. They thought the Philipines would be hit, or some other more western asset and the Japanese would not hit Pearl. They did fear saboteurs and thus on the fatal morning our fighter planes were lined up in nice neat rows at Hickam Field. Good for spotting spies planting bombs, but it sorta backfires when the problem is enemy planes strafing them and bombing them.
BTW, I never really liked FDR. If I could finagle up a good story against the socialist thug on this point I'd love to. But, unfortunatly the facts just ain't there.
