So much irrelevant BS. Nobody is going to give the Black Hills back to the Lakota. Forget that. But somewhere in the mashed up history of the region, It got lost that the duly elected United States Government granted to the Lakota tribe by way of treaty, sovereignty and ownership of the Black Hills area, defined in the treat, in perpetuity. Doesn’t matter where the Lakota came from, they were recognized at the time by the US Gov to be the sole and sovereign owners of the land. So what happened. It seems gold was discovered, right there in the Black Hills. Rather than work with the owners of the land to develop and share the wealth of precious metals, a corrupt Congress was induced to pass a bill which basically made it legal for them to take the land away, in flagrant violation of the treaty of Ft Laramie, and sell it off to private buyers.
The SCOTUS later agreed that this was a total injustice and awarded monetary damages. Even then they did not consider taking the land and giving it to the tribe.
So you can yammer all you want about the primitive savages and their warring tribes, stealing each others’ land. But the US was no better.
Just sneakier.
