I found this YouTube video fairly interesting: Seconds from disaster - Pearl harbor. [FULL EPISODE] - YouTube Tosh Minohara, Japanese Military Historian and "intel expert" at Kobe University in Japan, comes to some of the same conclusions, that Alan D. Zimm does in his article, The Pearl Harbor Myth (The Pearl Harbor Myth). I found the Zimm article in OpanaPointer's post: Pearl Harbor attack one big SNAFU Minohara claims a series of miscalculations and key errors were made in the tactical planning and operational control of the attack. The failure to bomb the tank farm, being one of the biggest. He also questions the thinking that the plan was so brilliant, because it was based on a false premise, that the destruction of the US Battleships would so demoralize the US, that we would lose the will to fight. Because it had the opposite effect and united the USA as much as any event could have, for war against Japan. The claim is made that, Vice Adm Nagumo, was not Yamamoto's first choice, instead he was chosen because of the traditions of the IJN. And that Nagumo didn't understand that the carriers should have been the priority target and was also too cautious a man for the mission. Supposedly, Nagumo rec'd intel just 6 hrs before the attack was to was to start, and could have called it off, due to the lack of carriers in the harbor. This would have been Yamamoto's choice under the circumstances. However, that's not what others have claimed about Yamamoto. Other say it was Yamamoto who failed to understand the importance of destroying the US Carriers, at least at that time. According to the video, Adm Nimitz said that a lack of fuel would set back the US War Effort 2 yrs. That seems like a long time to me. But, that clearly would have set back the US War Effort, and was a missed opportunity, along with the dry docks and sub base. I think some of the failures discussed in Zimm article are just the Fog of War, that often takes place in battle and were due in part, to a lack of radios in Japanese planes (ie flares would not have been used and that signal missed by some of the attacking planes). I do think though, Zimm is right about right about poor planning not being noticed after the PH Attack, but then showing up again during the Battle of Midway. Seconds from Disaster is a pretty good program from Nat Geo, who did very good articles on the 50th Anniversery of both Pearl Harbor and the Battle of Midway.
