Without trying to upset my US friends, this is how it looks from my side of the pond.
America is a superpower, it calls the shots, and all should obey, and at the same time love them for it. But shock horror, some countries have the effrontery to argue, and to fight back. HEY! says the US it seems you don't like us, in fact nobody loves us, and after all we tried to do for them. Showing them how to run their country and all that.
Neither the US, the UK or anybody else is the world's policeman, it has fuck all to do with us how other people run their countries. And when it come to criticising how other folks do things, we disregard the mote in our own eyes. It looks like you/we are interfering, and that pisses people off, so that's why they get mad.
