There, of course, is one somewhat surprising possibility: Hitler.
Even though Hitler did very stupid shit in OTL, he also had good ideas from strategic viewpoint. He was a veteran of the Great War, and refused promotions during it. He wished to remain in the army, but the army had no need for him after the restrictions. ITTL German Army is larger, and Germany is acting somewhat as world police, and a second war is probably still going to happen. France, Italy, and Russia would be revanchist, East Asia would still be a powder keg. Britain could be either neutral, or ally or an enemy. USA could be ally or neutral. I think that this would mean Hitler pursuing a career in the Army, maybe raising to a general. In a Central Victory, we wouldn't know Hitler as a genocidal maniac tyrant, but maybe as a hero of the Eastern Front in WW2. Or he could be a minor politician. Butterflies, butterflies everywhere.
