OK, so it's absolutely true that the Pearl Harbor advance-knowledge conspiracy is considered to be a fringe theory and is rejected by most mainstream historians. But I'm here to tell you that mainstream historians are dead wrong.
Yeah, it's a fact that FDR decided to move a large chunk of America's naval fleet to Hawaii to deter Japanese aggression. But this was actually one of the most boneheaded decisions and epic fails in Presidential history, and one that was foolhardy on numerous grounds; the fact that it left our vessels vulnerable from every conceivable angle, the fact that Hawaii was chock to the gills with Japanese nationals who could have easily infiltrated the base, the fact that Hawaii was 2,000 miles from the U.S. mainland and thus difficult to resupply, etc.
I mean, it's pretty clear that Roosevelt wanted the Japanese to attack, so he didn't have to attack them first. Duh!
