Because they don't wish to be considered as "another bloody yank" by Europeans. I don't have anything against Americans, but as a whole I think they are rather an arrogant nation. Arrogance comes from the way the media and the government/s portray the public. If I am right they make you believe that you are the best? Why? Because you are American!

It's a good way of building national pride, and I don't think my views are far from the truth.
