Here's the question I want to know: were you actually in a position to conquer America, or did you just manage to land troops there and run through the country before you were slaughtered? I could see it being vaguely feasible that Germany could make it all the way over there, but there's no chance in my mind that they would have the resources to be able to occupy and puppet America at the same time they're able to successfully defend the German borders. Sure you can make it to America, but can you survive another six months after doing that?
