Pearl Harbor Conspiracy Theory
The theory goes like this (in case you didn’t know), USA knew that Japan had plans to attack the naval base in Pearl Harbor and they allowed it to happen. They allowed it to happen so that they could persuade the American people to join in on the war (up until this point America had no interest in this affair that was so far away).
A recently declassified document dated just three days prior to the attack backs this idea up. Although the author of the new book which discusses this released memo believes that President Roosevelt didn’t think that Japan would be bold enough to actually attack us on our own soil (another commonly held belief for that time).
