Thats a hard question, and depends very much on the material conditions in a place. In countries where indigenous people are a majority, it would definitely mean giving state control to the indigenous. But in countries like the US where colonizers are the majority, I cant imagine how it could be solved in a good way. You cant really send white people away after they lived there for generations, but you also cant allow them to have majority control over the state.

Surely there must be some writing about this somewhere, maybe from the Black Panthers or other groups in the US?
