I would posit that had the Japanese invaded Alaska, Juneau, the allies would throw everything they have at defending the west coast. I think any commander that was pushing his 4 CV's around a bunch of nameless atolls 10000 miles away in the South Pac, while the US nation was going paranoid over IJN WC invasion, would have been fired immediately and any politician would be tarred and feathered
Something to think about - if you're going to play it "semi-historically" then everything the US has should be going to Canada, Alaska, and the North Pac. I doubt "lookie me over here raidin' Truk with my 2 CV's while my fellow citizens in Juneau are under IJN rule" would fly very well with the US populace, all things considered.
You and PH are both pretty honorable folks - adding a "how would the home islands folks or the US populace react to *this*" sort of game-play component might be worth discussing with PH
After all, does it really matter? We know how the war is going to end - Japan's going to be a charred hulk of an island cuz you are going to use nukes, right?
