About this invading Hawaii thing. Not possible for the reasons others have already mention. loose of the element of surprise, not enough man power and shipping. But just for grins lets say the Japanese did take Hawaii, they would still lose, but instead of the USA having a Europe first policy it would have had a Pacific first policy. Japan would be defeated before Hitler, the Amercan people would demand that. So the real effect of taking Hawaii would be to give Hitler a freer hand for a couple of years. Now that would be a game changer, yes Japan would be defeated but would Hitler. hmmmmm, maybe, maybe not.
Which would make the Bomb available while Germany is still fighting.
Hmm. I suspect this would have negated the idea that we dropped the Bomb on Japan out of sheer racism.
Can you say, "Goodbye, Berlin?"
It seems strange that, although Japan and Germany were allies and both were sworn enemies of Russia, they never coordinated their attacks. Japan took advantage of the war in Europe as an opportunity to grab colonial territory but it never really did much to help Germany. (Bringing the United States into the war by bombing Pearl Harbor certainly did not help Germany.) There was never any coordinated strategy.
I believe this is the major reason they lost the war.
