it might have contributed to the US winning certain battles in the pacificI mean that's part of the reason how the US won WW2 so it's plausible.
but the by far largest reason on why the US won ww2 was that it was outside the reach of their enemies (the nazis barely were able to attack london and the japanese struggled to reach pearl harbour for their big attack) while they had allies near the axis powers from which they could attack them
and as long as their allies werent knocked out of the war and their own desire to continue didnt waver so long would the US win the war and in the worst case they would still at best get a draw because both the atlantic and the pacific are far too large natural barriers for the axis powers to ever overcome and bringt he war to the US
and to bring it back to this story the biggest reason we continue to win is our spec ops teams that both bring us all relvant information and can take out the enemies elite units so our KMF can crush the infantry
