The Federal Government paid Mexico for it. That why it's Federal land.
Yes, but with whose money did they pay for the land....the taxpayer. The Federal Government does not own anything, they manage... nor should they...it’s all taxpayer money.
That’s why we get so upset with the 4 trillion dollars in debt....we owe the money, the taxpayers.
They paid money for the settlement of all claims, eviction and boundary adjustments, not for land. See the actual treaty articles in Post #115 and Post #142.
