They are a stupid lot. They cannot bring themselves to admit the USA runs the world. The USA is not just one of many nations -- the USA is THE NATION. The USA is bigger, stronger, and will always be the leader of the world. The DUmmies hate that fact. I guess that is why they try so hard to pretend it isn't the world's reality.
Also, DUmbasses, without the USA athletes' participation, the Olympic Committee could not charge the outrageous amount they do for broadcast rights. The ad and promotional revenue would be at least cut in half. In other words, without the USA the Olympics would be dead.
