This is utter bullshit. First, FDR did indeed want American involved in WWII, but not against the Japanese. FDR didn't care about what was going in Asia at the time. He wanted to attack Hitler.

agreed. the japanese had different codes for different types of messages. we had cracked the diplomatic code and knew that there was probably an attack coming, but did not know when or where. we did not break the military code until much later in the war. without the military message, we could not have safeguarded ourselves from the attack.
They weren't sure. My parents knew the Pathe News photographer who took the pictures of the Pearl Harbor attack. He had been assigned there while a cohort was assigned to the Phillippines to await an attack.
