You could say that some of the national borders as they exist right now are needlessly artificial.
Take Spain and Catalonia for example. The only reason that Catalonia is not an independent country is because Spain won’t let them be. There’s no real reason other than Spanish national pride and if there was a war between the two you could classify it as a civil war or you could classify it as a war between two countries, it’s entirely a matter of opinion.
But I don’t think that US politics has any real bearing on whether or not that happens. Political instability in the United States doesn’t really lead to any obvious change in internal politics for other countries. External policies obviously would change but not internal ones.


Alternative history is sort of difficult because we don’t know what the capabilities of those powers would have been. In order for the Nazis to have won the war a lot of people on both sides would have needed to make quite radically different decisions.
However it doesn’t take much theorizing to suggest that Nazi Germany would have probably had nuclear weapons in that scenario (the Germans were moving in that direction towards the end of the war, but were never really able to make much progress because by that point they were losing badly and didn’t have the resources anymore).
I can’t see how Japan would have ended up with nuclear weapons though. So I suspect a certain amount of power imbalance would have existed.
