Angus, I'm impressed, you might just be smarter than the whole Japanese armed forces command in 1941. Why in the hell didn't they take Hawaii and try to not only deprive USA of all ships or carriers that may have been there, but also maybe capture the half of them intact? They should have taken Hawaii instead of the Philippines. Philippines was on their side of the globe, and it had no prizes to compare with a whole fleet.
Take Hawaii, AND capture the fleet... then maybe coastal USA mite have been really skeerd.
I have something in my favour....67 years of what happened after Pearl within easy grabs.
I mentioned IWO, where the USA took an island vastly smaller than Haway, with absolute naval and air as well as troop superiority, yet it was a very bloody victory. Chici Jima (SP?) which was a Japanese stronghold wasn't even tried, just bombed.
Haway was a US stronghold with lots of potential, and very far from Japan. There is no way they could have done it IMHO, and YAmamoto's view of things will today hold scrutiny. He concluded that a war with the USA would not be won, - the only way would be to give the knockout in the first round, and for that Naval superiority was vital.
JApan needed to sink the US carriers and basically neutralize their naval power by that, since in his (correct) view, capital ships were obsolete in modern warfare against carrier groups. He concluded that Japan could not hold out to a continuing was against the USA. And he had studied in the USA..
