No, it wasn't, the US has made it's mistakes in it's past but we've managed to always overcome our mistakes and grow as a Country.
Agreed. No other country questions itself and strives to grow as America does. This is seen by some as a weakness, but is clearly one of our greatest strengths because it is done honestly and openly, which means we don't indulge in superficial, phony, pointless guilt. Our goal is active improvement, which we accomplish.
