Pinker had me re-think this desire for indigenous groups for self-determination, in his book, "The Better Angels...." His argument goes like this:
- Stable borders mean fewer wars/disputes
- Nations and their borders are relatively stable in the 21st century
- Clashes these days are chiefly with unsettled disputes with indigenous groups within a nation
- Once we go down the road of self-determination for every indigenous group, where does it stop? How do we distinguish a deserving indigenous community from an undeserving one?
- These groups are better off with greater peace if they continue to work within established national boundaries.

Of course, if a leader tries to "wipe out" an indigenous group (rid the problem), the world community should stand in the way and protect them. I am thinking of the Armenians, the Kurds, the native populations in Canada.
