The same intelligence would have alerted him to Japanese belligerence and the eventual war. Not even the Republican haters of Roosevelt would accuse him of being stupid. The crux of the revisionists' argument is that he knew war was coming and did nothing to stop it. We know now that Aircraft Carriers were instrumental to the victory in the Pacific. In 1941 you would have to be a clairvoyant to know that.
Any Military is always prepared for the last war.
A cunning murderer, who knew the future of naval power and victory. Both suppositions are contradictory. A general makes a stupid mistake and the blame for the resultant catastrophe is going to be passed down to the lowest ranking officer who can get blamed. Some poor 2nd Lt's head probably goes into the noose. In the Pearl Harbor stories though, the real case is that for over a half century the right wing that detests everything that FDR did have tried to paint him in an unfavorable light.
