What kind of "nation" lacks a naturalization process, or takes away citizenship for any reason except criminality?
How can the Cherokee Nation take the position that the U.S. cannot abrogate Indian treaties by implication but claim that Cherokees have done so in an election where treaty abrogation was not on the ballot and every time it was brought up tribal officials denied it? Their argument, if I understand it, is that the treaty never uses the word "citizenship." The treaty provision is above, and it is fair to ask what is unclear about "all the rights of native Cherokees"?
What does it matter to Indian country if the Cherokee Nation violates a treaty with the United States? I have already felt the impact, as I can no longer tell my students that Indians have kept their word in the face of perfidy. As Justice Black wrote, "Great nations, like great men, should keep their word." When Cherokees lose that argument, so do all Indians. That's not fair, but that's the fact of American politics.
