By was, I presume you mean five years ago, as the US broke the Treaty of Fort Laramie, pepper spraying and sicing guard dogs on natives in Standing Rock in order to build an oil pipeline. The natives testified at the UN human rights council as to what was happening.

But why? Would you still support this if the punishment cost you your job? Meanwhile, does this disincentivize the CIA from stirring conflict in another region? I think that biggest weakness with American foreign policy is that it's incapable of distinguishing between geopolitical interests and humanitarian interests. As a result, we aren't particularly good at advancing either.
The Black Lives Matter protests of the past year say yes.

We're literally still violating treaties with them.
That's why the Mitch Hedberg bit is funny (I used to do drugs... I still do but I used to, too) is humorous. It subverts your expectation that the thing you "used to do" is a thing you no longer do.
The US used to do horrible things to Natives... it still does but it used to, too.
In the same way, there's no shortage of people in America condemning police treatment of HK protestors (Repressed people fighting for freedom), who also support police treatment of BLM protestors (Rioters and lowlifes with no real grievances who just want to ruin everything).
That's because most people don't hold political ideology derived from first principles, they just check what their political tribe likes/hates, and follow suit.
Every human being in history is at the tail of a long line of injustices and atrocities. The current way to fix things today is to look at the situation people are in, today, and remediate as necessary. I'm the 4th generation from eastern european serfs, who were treated as livestock or part of the land. It doesn't affect me today in the slightest. I don't deserve reparations.
This isn't an argument against a social safety net or social welfare. It's an argument against crude race-based cash transfers that ignore who is and isn't hindered today by past injustices.
The answer, in the United States, is predominantly "No" from both sides of the political spectrum to the first question, and "Mostly No/No" to the second.
I'd also like to point out that even the Soviet Union/the Russian Federation flirted with reparations for victims of Stalin's repression.
