Indeed. The analogy I was initially going with was that the US is the High School Freshman who ends up Quarterbacking the varisty team to the championship and then becomes an insufferable ass.
The problem with the analogy, and with simply calling the US arseholes, is that it is both very true, and very untrue. The US is far more conflicted than that.
We are self-centered, assholes, bullies, and ignorant hate mongers. We also really, honestly, want the world to be a better place. We want things like democracy in places that are ruled by tyrants. When disasters strike we donate our time and resources to help. We have good and bad, but, for the most part, we are more good than bad.
I also don't think you can have it both ways. The rest of the world looks at us and our rose-colored glasses and wants to slap us for being so naively unrealistic. But if we behave like any other country, suddenly we're help to that same standard we were previously being mocked over.
It is far, far more complicated than that.
