Interesting details on how FDR government and military knew of Pearl Harbor attack and attack on American's largest Pacific bomber fleet in Philippines and blocked local commanders from taking defensive action. And if not a conspiracy why are key Japanese code decrypts kept from public 60 years later for "national security" reasons when other decrypts of the same codes are publically available? Expect the truth to come out publically within the next year...

24 September 1941, the " bomb plot" message in J-19 code from Japan Naval Intelligence to Japan' s consul general in Honolulu requesting grid of exact locations of ships pinpointed for the benefit of bombardiers and torpedo pilots was deciphered. There was no reason to know the EXACT location of ships in harbor, unless to attack them - it was a dead giveaway. Chief of War Plans Turner and Chief of Naval Operations Stark repeatedly kept it and warnings based on it prepared by Safford and others from being passed to Hawaii. The chief of Naval Intelligence Captain Kirk was replaced because he insisted on warning HI. It was lack of information like this that lead to the exoneration of the Hawaii commanders and the blaming of Washington for unpreparedness for the attack by the Army Board and Navy Court. At no time did the Japanese ever ask for a similar bomb plot for any other American military installation. Why the Roosevelt administration allowed flagrant Japanese spying on PH has never been explained, but they blocked 2 Congressional investigations in the fall of 1941 to allow it to continue. The bomb plots were addressed to "Chief of 3rd Bureau, Naval General Staff", marked Secret Intelligence message, and given special serial numbers, so their significance couldn't be missed. There were about 95 ships in port.

7 December 1941 very early Washington time, there were two Marines, an emergency special detail, stationed outside the Japanese Naval Attache's door. 9:30 AM Aides begged Stark to send a warning to Hawaii. He did not. 10 AM FDR read the 14th part, 11 A.M. FDR read the 15th part setting the time for the declaration of war to be delivered to the State Department at 1 PM, about dawn Pearl Harbor time, and did nothing. Navy Secretary Knox was given the 15th part at 11:15 A.M. with this note from the Office of Naval IQ: "This means a sunrise attack on Pearl Harbor today." Naval IQ also transmitted this prediction to Hull and about 8 others, including the White House (PHH 36:532). At 10:30 AM Bratton informed Marshall that he had a most important message (the 15th part) and would bring it to Marshall's quarters but Marshall said he would take it at his office. At 11:25 Marshall reached his office according to Bratton. Marshall testified that he had been riding horses that morning but he was contradicted by Harrison, McCollum, and Deane. Marshall who had read the first 13 parts by 10 PM the prior night, perjured himself by denying that he had even received them. Marshall, in the face of his aides' urgent supplications that he warn Hawaii, made strange delays including reading and re-reading all of the 10 minute long 14 Part Message (and some parts several times) which took an hour and refused to use the scrambler phone on his desk, refused to send a warning by the fast, more secure Navy system but sent Bratton three times to inquire how long it would take to send his watered down warning - when informed it would take 30 or 40 minutes by Army radio, he was satisfied (that meant he had delayed enough so the warning wouldn't reach Pearl Harbor until after the 1 PM Washington time deadline). The warning was in fact sent commercial without priority identification and arrived 6 hours late. This message reached all other addressees, like the Philippines and Canal Zone, in a timely manner.

7 December - 9 hours later, MacArthur's entire air force was caught by surprise and wiped out in the Philippines. His reaction to the news of Pearl Harbor was quite unusual - he locked himself in his room all morning and refused to meet with his air commander General Brereton, and refused to attack Japanese forces on Formosa even under orders from the War Department. MacArthur gave three conflicting orders that ensured the planes were on the ground most of the morning. MacArthur used radar tracking of the Japanese planes at 140, 100, 80, 60, down to 20 miles to time his final order and ensure his planes were on the ground. Strategically, the destruction of half of all US heavy bombers in the world was more important than naval damage in Pearl Harbor. Either MacArthur had committed the greatest blunder in military history or he was under orders to allow his forces to be destroyed. If it were the greatest blunder in history, it is remarkable how he escaped any reprimand, kept his command and got his fourth star and Congressional Medal of Honor shortly later. Prange argued, "How could the President ensure a successful Japanese attack unless he confided in the commanders and persuaded them to allow the enemy to proceed unhindered?"
