"What If's" are always interesting, but moreso to me for the War in Europe.
I think the Germans could have produced a different result by not attacking Russia, or keeping up the pressure on the RAF, not declaring war on USA, or any number of interesting scenarios that possibly could have changed the war's outcome. Even if the RAF is destroyed I don't think the Brits surrender, but I guess you can argue it's possible.
I struggle, though, to come up with any what-if that would produce a result for Japan other than it's destruction. Better pilots, more carriers, reverse Midway, etc......the result to me is all the same. Japan gets crushed in 1944, period. I suppose it's theoretically possible that Japan retains more territory by withdrawing from China and suing for peace, but the Army would NEVER have allowed it, even if the Emperor had ordered it.
