A Pearl Harbor Conspiracy?

If you’re a history buff like me, a good historical mystery or controversy can make for excellent reading, even if you have doubts as to how mysterious or controversial the subject is. For example, did the American Government and President Franklin Delano Roosevelt have advance information about Japan’s attack on Pearl Harbor and was this fact later suppressed, either to conceal incompetence or because the President wanted an act of aggression to force American into war with the Axis Powers?

One of the most written-about pieces of this historical puzzle is the so-called “West Wind Execute” message, Japan’s code phrase to advise its diplomats abroad that an attack on America was imminent. In West Wind Clear: Cryptology and the Winds Message Controversy – a Documentary History, the National Security Agency’s Center for Cryptologic History has tackled the complex history of this message, when it was sent, and why its existence or non-existence has exercised the imaginations of academics, amateur historians, and conspiracy buffs since the 1940s. Crucially, it includes many key documents, some never before published, dealing with the voluminous Japanese signals traffic leading up to the Pearl Harbor attack and the timing of signals interception and decoding.

The thrust of West Wind Clear, which is backed up by meticulous and extensive research and documentation, is that the Winds messages did exist, but they were only one string among many Japanese communications instructing diplomats to burn their code books and take other 11th hour measures to prepare for war. In fact, the actual West Wind Execute message was broadcast after the attack began. The authors state that the main source of continuing debate over the “who knew and when” question resulted from a number of contradictory statements by a well-respected American cryptographer, Captain Laurence Safford, USN, whose reliability as a witness was undermined during the hearings of the 1946  Joint Congressional Committee investigation of the Pearl Harbor debacle. He was unable to produce any documentary evidence and was shown to have changed his story of a pre-December 7 West Wind Execute message numerous times.

Despite these findings from a committee whose members included some who gladly would have found neglect or malfeasance at the root of the Roosevelt Administration’s handling of the run-up to war, the West Wind controversy has persisted in popular accounts that lent credibility to the stories of Safford and Ralph Briggs, a radio operator who many years after the fact claimed to recollect a West Wind Execute message before the attack.

West Wind Clear makes a strong and well-documented case against a suppressed warning of war. For conspiracy theorists, who tend to operate within a closed intellectual system, no evidence is convincing enough, but to me, this story of bureaucratic confusion, stress, and misunderstanding seems much more authentic (and common) as an explanation for “the fog of war” surrounding the Winds messages.

    So any learned person who listens knows that there is more to 9-11. That the terrorists weren’t in Iraq, etc. That we had warnings since the 80’s. Pearl Harbor was also somewhat of a conspiracy. The President made a plan to intentionally provoke Japan into “striking first” so that the U.S. could enter war with Europe (which citizens were opposed to). What’s another government lie, with about equal standing and importance of these ones?

    2) Moon landing was hoax

    3) Pearl Harbor attack was inside job and Japan falsely accused by government

    4) JFK assassination inside job

    Hello Govbooktalk,
    Thanks for the above, 9/eleven was inside of work whose mastermind was Bush. Pearl Harbor was within employment whose mastermind was FDR. Japanese ended up innocent and unnecessarily suffered two atomic bombings. Federal government conspiracies keep going to this day. The most modern example of government conspiracy remaining Toyota recall of unintended acceleration considering the fact that Authorities Motors was struggling. Swine Flu vaccine was a further modern govt conspiracy and so is the up-to-date economic downturn which commenced in December 2007. The moon landing was a hoax very. I am a effectively educated gentleman with degree in mathematics, so i am not ignorant.
    Kindest Regards

    Regarding the controversy about FDR’s advance knowledge and intent, we very often confuse the general knowledge of the overall situation before an event as proof of specific knowledge of the event. We knew we were inching toward a fight with Japan as a result of the embargo and there was an expectation (based on Japan’s prior military actions) that it would be a surprise attack on a holiday or other period of stand down. It was expected that the strike would likely be against a key base in the Western Pacific (like the Philippines) not against our bases outside of the expected theater.

    I remember speaking with a retired CG Captain in the 1990s who was a USNR Ensign on a destroyer in the Atlantic in ’41. He said the news of the Pearl Harbor Attack was more of a shock than a surprise. At the same time, the U.S. was already at war – with Germany in a naval war that had been raging since the summer. FDR probably didn’t need an excuse in the Pacific for an expanded war against Germany – all he needed to do was wait for matters to deteriorate further.

    Allowing the Pacific Fleet to be devastated was not in FDR’s interest regardless of what side we ended up fighting and it doesn’t make any sense. At the time of the attack, battleships were still viewed as the primary weapon (not the aircraft carrier) and Kimmel’s battle plan for taking on the Japanese fleet anticipated a big gun duel in the mid-Pacific (which is also what most of the Japanese admiralty expected as well). FDR was primarily concerned about Hitler and there was no guarantee that a war with Japan would lead to a war with Germany (at this point, Japan had declined to join its Axis partners against the U.K. and the U.S.S.R.). As it was, Germany’s declaration of war on the U.S. was an act of Hitler’s hubris as opposed to any treaty obligation.

    I think we tend to look for conspiracies in something like this because we think that we should have been able to stop something like this. The reality is that the key to victory was the audacity of the plan and the technical excellence of the Japanese Navy in pulling it off, coupled with a too-conservative assessment of Japan’s capabilities and a confused analysis of the mounting threats by the U.S. commanders.

    I tend to agree that President Roosevelt was inclined to wait for something to happen that would help him to rally the American people and gain support for assisting England. I’m not so sure he suspected the scale of the attack would be as large as it was, considering that the Japanese were aware of our capabilities to some degree. The Japanese Admiral knew enough to comment that he feared all they had accomplished was awakening the sleeping giant. I do hope we are not sleeping as much these days.

    Thanks for this reference on the “Winds” messages; I’ll check it out. More to the point might be a German intercept, via a radiotelephone listening/descrambling post on the Dutch coast, of a 26 November 1941 conversation between FDR and Churchill discussing the upcoming Japanese strike at Pearl Harbor in some detail; evidently the British were quite a bit ahead of the U.S. when it came to decyphering the IJN code. For documentation and discussion, see Gregory Douglas, GESTAPO CHIEF- THE 1948 INTERROGATION OF HEINRICH MUELLER, Vol. I, pp. 42-55, 246-252.

    My father was stationed at Hickam on 12/7/1941.

    I learned this in Third Grade when our teacher read his interview for the 15 Anniversary of the Attack. She left out his name and then announced “This young airman’ son is in our class today” and it was ME!

    That night at supper I asked him if it was true and he was as surprised as I had been for me to ask.

    I had his interview if anyone wants to read it. At the very end he states ” I just hope they never allow this to happen again”.

    On 911 I was sitting aside of my Uncle who also fought in World War Two and he said much what my father had said. “THIS WAS NEVER SUPPOSE TO HAPPEN AGAIN” after Hickam and Pearl Harbor.

    It did happen again and it will again with the people we have in Washington trying to run our country.

      We did have a navy and an air force, but we only had a 100,000 standing army. We did pick up the Japanese on radar coming into Oahu, north of the island. Those guys thought that the planes were B-17 bombers coming in from California (They arrived during the attack…great way to start a war, under attack). The destroyer Ward sank a Japanese midget sub. about an hour before the attack, but it was Sunday morning and everyone was laid back. Anyone with any sense whatsoever should have known that the Japanese would have attacked us when we cut their oil supply off (Back then, the U.S. produced about 75% of the world’s oil supply. The Japanese are a very proud people who wouldn’t let the U.S. shut them down. The Japanese attacked in Southeast Asia to get an oil supply to survive. Have a good day! :-)

      I’m not so sure the problem was the technology but rather the lack of an ordered process for assessing threats, communicating, and taking responsive action. We’re used to the “DefCon” approach that heightens readiness as the perceived threat increases. Back then theater commanders had the responsibility to respond to threats within their discretion (hence the deriliction charges against Short and Kimmel and their defense that the latest “war warning” before the attack was indistinguishable from previous warnings). I think the DefCon structure was developed during the Eisenhower Administration.

    Thanks for this interesting post. I checked the GPO Catalog to see if my local depository library had this title. Please note that it was not distributed in print to any depository. It is available electronically via the depositories that subscribe to the item no. which covers this publication. A depository would have had to purchase this title. I had difficulty locating this title in the GPO bookstore. fyi.
