Having lived on the Navajo Reservation for a brief time, I can tell you that there were quite a few Whites that the Navajos would have happily kicked off the reservation. I suspect that's also true in Canada. Are there reservations for Native Americans in Mexico? I didn't think so. How about the Maori?
Wouldn't it be possible to consider Israel a "reservation" for Jews? Jews are obviously not safe anyplace else.
