I understand the to the winner go the spoils...lose a war, regardless of who declared or started it and there goes your land. Human history...but I also think that treaties made at the time should be honored. Apparently Congress can unilaterally change the treaties, as per another SCOTUS decision in https://www.oyez.org/cases/1900-1940/187us553 https://www.oyez.org/cases/1900-1940/187us553 In a unanimous decision, the Court affirmed the Court of Appeals and upheld the Congressional action. The Court rejected the Indians' argument that Congress' action was a taking under the Due Process Clause of the Fifth Amendment. Justice Edward D. White reasoned that matters involving Indian lands were the sole jurisdiction of Congress. Congress therefore had the power to "abrogate the provisions of an Indian treaty," including the two-million acre change. Justice John M. Harlan concurred in the judgment.
