>does this actually affect the war?
Maybe the war ends in '47 instead of '45. Japan probably gets even more devastated by air attack (including nuclear) than it did IRL. If supply of military aid to the UK and USSR is also diminished/delayed because of the more precarious American position the war in Europe might drag on long enough for Germany to get nuked as well. The resource disparity between the Allies and the Axis powers is just insurmountable once America enters the war.
