@krellin-
1. Separate but Equal has essentially nothing to do with the New Deal. It has everything to do with the moral standing of the Supreme Court.
2. Hmm, let's see here. We installed the government in Germany, Japan, Italy, South Korea, Austria, and the Phillipines, amongst many other places. And then, the governments we installed gave us bases. You don't see any sort of implied threat there?
3. Finally, compared to the European powers during their era of explicit colonialism, we are a much better hegemon. That's a low standard to beat, however. Although Mao Zedong was a less brutal and irrational dictator than Pol Pot, that doesn't exactly make him a good guy, does it? No, it means he wasn't the worst ever. And the US hasn't been the worst hegemonic power ever. But we've killed tens of millions of people in order to attain and maintain our hegemony.
