Looking at the wikipedia list you have to scroll through like a fifty names to get a non-German and like a hundred to get any Allied pilots.
And Erich Hartmann had almost ten times as many kills as the top English or American pilots.
Obviously this didn't win them the war or give them any of what the top Luftwaffe guys promised, but why did they have so many aces?
In case no one comes through with more today, there's this post on basically the same question from years ago, with a nice response from u/eidetic.
