It's very good question. I think it would be extremely difficult.
If you go back to the Soviet period—which, again, my colleague Professor Altstadt, the historian, would underscore as well—and if you look at the North Caucasus during the World War II period, the Soviets manipulated those borders and moved populations, populations that are still trying to come back and peacefully integrate.
You would have a similar situation with two populations claiming the same territory and literally sometimes the same home. As much as it would be wonderful if the two countries could work it out, it would be helpful to have a mediating group.
