I really don't understand. The US is a primary source of income for so many countries. We are sending billions overseas, keeping little for our own government, but we are still hated.
And WTF is with the ugly American pig stereotype? You know how many dirty French and German tourist I've seen over here. Its a plain fact that when people go on vacation they acted like assholes.
And also it doesn't matter if the US could beat Europe in a war, or vice versa, because when China attacks, which they well eventually, we're both screw if we don't become allies, and even then we're screw because so many European country hates the US so much there'll never agree to take action, so we're be sitting ducks.
