Contrary to what the Native American race-baiters like to argue, "sovereign" Indian Nations have never been treated exactly like foreign governments. They are subject to federal law and, to the extent federal law decrees it (as in this case) state law.
ARTICLE 2. The United States acknowledge the lands reserved to the Oneida, Onondaga, and Cayuga Nations in their respective treaties with the State of New York, and called their reservations, to be their property; and the United States will never claim the same, nor disturb them, or either of the Six Nations, nor their Indian friends, residing thereon, and united with them in the free use and enjoyment thereof; but the said reservations shall remain theirs, until they choose to sell the same to the people of the United States, who have the right to purchase.
Chief Justice John Marshall used the phrase "domestic dependent nations." He also wrote that "their relations to the US resemble that of a ward to his guardian."
Interesting legalese....
Regarding "race" the Iriquois have one of the highest percentages of the X-factor, a string of DNA code found only among some Europeans, some North Africans, and a whole lotta' North American Indians.
The "X-factor" has been found in DNA recovered from pre-Columbian material ~ ergo, it didn't arrive on the Mayflower.
What that means is the State of New York and its running dog lackeys are trying to steal land and property from white people (not some other "race").
