"[after Japanese officers in the Nagato wardroom applaud him over news of the Pearl Harbor attack announced on Japanese radio] I had intended to deal a fatal blow to the American fleet by attacking Pearl Harbor immediately after Japan's official declaration of war. But according to the American radio, Pearl Harbor was attacked 55 minutes before our ultimatum was delivered in Washington. I cannot imagine anything that will infuriate the Americans more. I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve."
