Generally (especially initially) the people obsessed with Roosevelt-as-Antichrist conspiracy theories knowing about Pearl Harbor but not telling anyone and whatnot were the same people who worshipped McArthur as a God.
Yet this was after McArthur was fully aware of the Pearl attack, and it was entirely his responsibility.
Regarding the initial story, they're suing the US and not Japan because they think they have a better chance of winning. But it makes absolutely no sense. Japan attacking the Phillipines, by itself, is plenty enough justification for war. And ironically, I've never heard, and in histories have read almost nothing, about US Civilians in the Phillipines being held captive by the Japanese. It seems clear to me that this was almost totally unused in US propaganda.
