Let's not forget that EVERY country that was a world leader, at one time, rec'd the same comments that America is getting today.
America is far from perfect, but compared to many others its heaven.

China is 5000 years old- America is 250 years old- who has landed on the moon?(among the many "first") who saved Europe TWICE in the last 100 years?
Without America the world today would be a very bad place to live....
