Expectation is exactly the point. We don't expect a movement like the Iraq insurgency to uphold human rights, and so the fact that they don't isn't something that's being brought up every 2 days in the papers. Guess what though - We don't deal with them either. We don't trade with them, we don't talk to them, we don't cooperate with them, and we throw them in prison whenever they're identified or, if they're armed, kill them.
If we were to expect the US to behave like they do, we would have to also start throwing every US citizen in jail, stop all relations, impose a complete trade embargo, bomb every US base in and around Europe and so forth. That's what we would morally have to do if it comes to the point where we expect the US to behave like the insurgents do. So I think the fact that we expect much higher standards from the US is a good thing... don't you? If you eventually end up no better than the insurgents, you basically forfeit everything.
