The concept is simple enough. Take an ethnically or religiously mixed population at a disputed area somewhere around the world; lets call them group A and group B to keep things generic. Group A and Group B both claim ownership upon the same piece of land and have been fighting over it for years, but through some combination of being sick and tired of war and outside coercion to negotiate, group A and group B decide to sit down and sign a peace treaty. Under the deal, a border is agreed upon by both parties, and where there was once a mixed population, at the end of the process, one side is now homogeneously composed of group A, and the other side of group B.
Homes are wrecked, land and property is permanently lost, the displaced will almost certainly have trouble readjusting after being uprooted, and there are unavoidable casualties as some of the transferred populace resists their relocation. On the other hand, there is now a clear, mutually respected border, and the number of minorities left on either side of the border is now miniscule; so effectively, the region is no longer disputed, and the chance of a future war igniting over it has dramatically decreased.
Now, historically speaking, population transfers used to be seen as a practical method of conflict resolution. Take for example the Greece-Turkey border which was stabilized through the practice a century ago, and hasn't had a war fought over it since. In modern times however, the practice has been declared a human rights violation due to the amount of immediate suffering it causes; while some still advocate for it, its by and large no longer sought after as part of a deal.
So what do you think, would you be willing to accept a forced population transfer as part of a peace deal? Or is the trauma of forcibly removing people from their home too great, despite the potential refusal to do so will result in the re-igniting of the conflict later?
