It is amazing what USA has accomplished in such a short time in history, since 1776!
Probably it's the most formidable country in the history of mankind as we know it.
Yes, there were, there are, and there will be problems and mistakes - some of them quite big - but hey! what country is perfect?
I wish that EVERY country, including my adoptive USA and my native Romania, had politicians and leaders with much more patriotism, throughout history.
