In 1965 I was assigned to write a paper in a history class on the culpability of the Army and Navy commanders at Pearl Harbor for the attack there. I read (much of) the Congressional report on the subject and was shocked at the evidence showing he did. About 1998 my daughter told me her University of Florida history book stated that most historians today believe FDR knew the attack was coming and withheld the information. I don't know the truth, but if God put a gun to my head and made me guess, I would guess that he did.
