i mean every bit of it. What historic blunders do you regret? What historic achievement are you most proud of as an American?
No one can say they are proud of every single event in their history ... be it national or personal. If you are can't point to a single mistake in our history then we are only acknowledging a filtered version of it. Filtering out the bad bits only skews your perception going forward.
That being said, I believe, that America and Americans have been a force for good in this world. We can relish in our collective achievements and reflect on our collective mistakes.
I am most proud of America as a concept... the idea that people can come from all over this planet for the purpose of achieving the greatest amount of freedom ever allowed a people.
We may not always achieve our collective goals, but at least we have them.
