That is exactly why she is where she is now. The BIA is a genocidal agency that has no place in the modern world. All of the former colonial empires have gotten rid of the bureaucracy related to ethnic groups. Only the U.S. has it. This bureaucracy is a facade for genocide.
Reservations are bad.
The Indians should be allowed to go it alone. Their sovereignty should be honored. It is a higher sovereignty than the individual states. It should be honored as much as each reservation wants it to be honored. The BIA should be abolished and any land claims should be settled through the Department of Agriculture and the Department of Interior.
