I really don’t know who they would have us give the land back to. On the southern plains, the Comanches drove out the Apaches, who drove out somebody else previously. The whites were just the last in the chain.
Where I live, the last “dominant” tribe was the Osage, which moved south into the area, decimating tribes already there because the Osage (which didn’t really live here, for the most part) wanted this for their “hunting preserve”. I have read where the biggest part of Kentucky was also a “hunting preserve” for sedentary tribes in the Ohio Valley, and was kept largely depopulated.
But the archaeological evidence also points to major depopulation of the area in which I live, long before the arrival of whites. Nobody knows how that happened, or why. So, when the Osage decided to make it their “hunting preserve” they would not have had to kill very many Indian residents who were already there.
Nobody knows who, exactly, the Osage dispossessed here. Ultimately, some Indians moved here from the east. Some were warlike, some not so much. Ultimately, the Osage moved to the western plains on their own, because of the in-migration of other tribes and whites.
There is scarcely a person in this part of the country who does not claim at least some Indian ancestery; usually Cherokee. A very small percentage of Cherokee ancestery will qualify one as a “tribal member”. I have known blonde, blue-eyed people who have their tribal cards.
So, who gets what?
But I guess the UN is determined to make its anti-western proposals, however preposterous they might be.
