Conspiracy theory Pearl Harbor

Answer 1

It has been strongly suggested that Franklin D. Roosevelt had advanced warning of the imminent attack on Pearl Harbor, yet allowed it to happen. His presumed reason was that it would be an excuse for the U.S to enter World War 2 (which he had wanted to do from the earliest days of the war, but the Republicans in congress stonewalled this at every turn), thereby converting the crumbling U.S economy into full-on wartime production and extending the draft. All of these things helped end the Great Depression, which was his long-term goal since entering the oval office.

Basically, "he broke eggs to break an omelette" is the jist of the theory.

Answer 2

The conspiracy theory is that the USA knew about the attack in the first place, and that Roosevelt just let it happen so that it would give America a reason to enter the war.
