I was not attempting to excuse it. I was simply pointing out that it was part of something that United States of America, ended up being humanity's greatest achievement to date.<p>Say what you want about America, but it pioneered most of the rights that the entire first world enjoys, and which are spreading throughout the rest to this date. Capitalism, civil liberties, social mobility. None of them were invented here perhaps, but the whole (which is far greater than the sum of its parts) was.<p>There's a reason you've probably never seen a public hanging or a head on a pike. There's a reason wars victimize fewer and fewer civilians every decade. America's history is certainly not without blemishes, including this one, slavery, a few ill-advised wars, etc. But on the whole it's been an incredible windfall for humanity.<p>So no, I wouldn't undo the whole thing. Nothing is perfect, and to take the view that we could have made the omelet we enjoy today without cracking a few eggs along the way is naive at best.<p>It's hard to make any argument that the holocaust was part of a bigger package that benefited humanity, so the two are dissimilar and entirely unrelated.
