The Native-American Indians have been backed into the furthest corner that they can possibly be backed into. There is nowhere else for them to go.
When people say things like this it makes me wonder if they are using the words metaphorically or if they actually think Native Americans are forced to live on reservations.
Well, I guess they can agree to lose their heritage and identity, and stop believing in the spiritual nature of life and Mother Earth and how to live in harmony with her, and embrace the white man's crude idea of civilization which includes raping the earth of its precious resources and stealing land that belongs to someone else etc.... Yes they have a choice to assimilate, but it's really no choice when their belief system is so completely on a different plane of reality from one that wants to destroy our "home".
