Just to add a speculation...Germany would be better off today if the first nukes had been dropped on Hamburg and Berlin, and instead the Turks were later forced on Japan...
I’ve thought about what would have happened had the Germans won WW I. I would make the case that ultimately the world would have been better off. No Hitler. Maybe no Bolshevism. German rule of Europe under the Kaiser would have been much more benign than certainly under the Nazis.
