>>43366083for one, i swear i've seen this very thread with this very header image many times before, so we're treading on old ground here.
japan would never have actually invaded the continental united states, it would be too costly, and the insurrection would have been so protracted and entrenched it would have been utterly worthless to even try.
the only potential scenario requires japan to have swept their military efforts in asia such that they could have weathered the pacific theater long enough for the states to lose their taste for combat - and would have required that the USA had never invented the bomb, obviously, and that the us hadn't won key battles in the pacific.
if these things were to have occurred somehow, america would have basically given up all the islands in the pacific, and hawaii, and japan would have basically let the states alone. the most they could do is perhaps extract punitive trade arrangements with them from a position of total dominance of the pacific and all of it's resources.
it would require far more expertise to determine what would happen culturally in the states if they'd lost the pacific theater. certainly, the states would not have risen to a global superpower, nor would it dominate international politics. vietnam, all the business in southeast asia and the middle east, and the entire cold war would not have happened in the same manner. it's possible that america would not have been able to oppose russia, and would have been forced to allow communism to spread throughout various parts of the world.
so, you'd probably be looking at a japanese empire in much of asia, communism going strong (until it's inevitable collapse in russia because of various reasons including it not being an actual viable economic system), and the complete lack of any idea of USA exceptionalism.
not possible to determine how things like civil rights would have turned out, but tech progress would be slowed in the states, amongst other things.
