What is the most plausible way for the Second World War to be a divided fight? To be more descriptive, here is what I have in mind: the European front of the war proceeds as it did in OTL for the most part, minus any overt aggression by the US or the Axis in the North Atlantic. When the Japanese bomb Pearl Harbor, the US goes to war against Japan but does not war with the other Axis powers.
I'm sure I'll get a few call-outs on here in regards to this being ASB, but I think the idea holds promise. People, especially in the States, tend to overemphasize the role of the USA in WWII; how would the European powers fare against the Axis by themselves? I think it's safe to assume that the US would defeat the Japanese ITTL as well, so how would the world look with a Pacific Ocean that is, at least during the 1940s, dominated by the USA? Finally, how would this affect post-WWII politics, especially if the USSR ends up in relatively the same position (or moreso) in Europe that they did OTL?
