The fact remains that Oklahoma is settled by Americans, and there's no reason to give away that land. Possession is 9/10s of the law. The only precedent giving it up sets is weakness. And I doubt a precedent of the government keeping its promise is really going to be followed in the end anyway. Do you think they are going to keep an ancient promise when it hurts white people and then also go on to keep promises when it helps white people? If you're here on this site I wager you've been paying attention for long enough to know that's not how things work.
