Greedy or not, somebody was going to become the dominant and even hegemonic world power after that colossal war and the nation state dynamics that followed it.

Greedy or not, somebody was going to become the dominant and even hegemonic world power after that colossal war and the nation state dynamics that followed it. Would you have preferred that it be something like the then still Stalinist USSR, or later perhaps the deeply authoritarian (and under Mao batshit crazy on its internal policies) China? Given the inevitable rise of at least one dominant power, I prefer that it was the United States with its generally benevolent democratic traditions to model off of (even if it itself often poorly applied them overseas)
