From reading Saburou Sakai's autobiography, the Japanese pilots that ran the mission were informed by their superiors that they had notified the Americans of the attack, as their personal honor demanded. While technically true, the Americans stated that the Japanese had been broadcasting attack plans for some period of time that I do not recall, but of significant length that the Americans had no choice but to disregard it: an incredible situation of crying "Wolf!" too many times (a situation the Japanese pilots were not aware of). I agree that Pearl Harbor was sacrificed to get America into the war, but a lot of the little details of the situation get overlooked by people trying to demonize either side. It almost worked out too perfectly for the globalists.
