Not entirely inaccurate. There was always an undercurrent of us treating Native Americans as sub-human. We would ally with them to get what we need, then break our side of bargains because they were not entirely seen as deserving of them. We saw a few small parts of this behavior in 2016-2020, but we were doing it to countries and agreements who do just fine without us. When the deal is “we will guarantee you safety, but you can’t keep this land” and “we will guarantee you safety” falls away, then it is basically genocide.

I think it was unforgivable, but it certainly means the US doesn’t have some special moral highground.
