Well, we are not the USA so no, we didn't win as that. But just make it about 2 empires and forget the rest.
Earlier you said "we won and they lost." If it's all about "empires," then I would say that "we" are doing it wrong.
At least as far as the characteristics and demeanor of our national leadership, it's not an "empire" at all. At best, it's more akin to a powerful Mob family which operates mostly underground, conducts secret wars, engages in treachery - all the while trying to pass themselves off as "legitimate." As to your point about "realpolitik," most governments see that as something shameful and something to hide (or at least minimize).
