The US Constitution allows the country to enter into treaties which are otherwise unconstitutional.
It has entered into a treaty with a different nation with overlapping boundaries, due to the nature of the treaty, and it has to honor that. Congress can further renege on their promises and change the treaty, but the reason that treaty exists is because a prior older unconstitutional act involving the relocation of those indigenous nations to that area of Oklahoma. So Congress and the President won't touch it, not just the current one, but no congress and President will touch this without consequence.
So its not about what we want, its about atonement and having to deal with this incongruency now in the 21st century. We are still in the process of recognizing that there are hundreds of separate semi-autonomous and co-dependent nations within the continental US, and we have to have diplomatic relations with their people, people that cannot be simply deported when they commit a heinous crime, and share a porous border with the rest of the country.
