The best thing is that everything that doesn't comply with the official line of the Government is automatically tagged as "conspiracy theory"

Just quickly read through some parts of that text, if what Stinnett says is true, then Roosevelt must have known. But if he knew, why didn't he warn the naval base? Was it essential that the attack was devastating? Or was he afraid the Japanese wouldn't attack if they got a last minute warning about the new situation on the base?

To me it seems much more likely that Roosevelt and his generals vastly underestimated the Japanese naval power even though Japan was regarded hostile at that point.
I think they thought the base was well able to defend itself when Japan would attack with ships.
