Who ever gets elected is not only the US president, but also plays an important role in global afairs and has on finger on the NUKE button. So yes, even we can't vote, we get put up with your mistakes

I am quite sure that history has proved that the US can do a lot more than make mistakes. Take a look at WWII, for example. The Europeans could have stopped Hitler dead in his tracks in the 1930's before the war ever started.
