Maybe not now, but that's not the point. The point is that we're all human beings and what history shows us again and again is that as a species we are capable of talking ourselves into group-level insanity.

There's nothing about history that should lead anyone to imagine that the capacity for group-insanity is somehow unique to any so-called "race" or national identity.

If you really want to argue that Americans are somehow uniquely subject to such things, you then have to account for the fact that a plurality of Americans are directly descended from European ancestry which in turn means that any difference has to be cultural as opposed to some kind of genetic quality innate to Americans.

The upshot here is not that the US is somehow unique, but is rather that the US is precisely what happens when Europeans take over a brand new continent peopled by civilizations that lack the technology and microbiology to resist.

Again, this idea of yours, that Americans are somehow unique or special, is patently absurd given what we know of history.
