I will clarify: I love America. My favorite music comes from America. I couldn't name a great heavy metal band coming out of the Soviet Union even though they existed - and there is a clear reason for that.
It IS a great country.
Discussion about which is the BEST country opens a can of worms that just creates a load of problems - first off, how you measure that is an exercise in bias in and of itself, and second, when you have people of every country saying that theirs is the best, people inevitably get into aggressive dick waving contests and ultimately people get killed. Only one country can be the best, and the punchline is that ALL countries could do better, even the ones we love.
