I’m perfectly fine with a negotiated settlement. Ideally, the areas where more people want to stay in Ukraine should stay with Ukraine and the areas where more people want to join Russia should join Russia. That would minimize the amount of displacement while allowing people to live under the government of their choice. My real issue is that Ukraine won’t negotiate at all, even on Crimea, and I just think that’s unreasonable.
the Muslim/Hindu migrations between Pakistan and India during partitioning
This was the biggest example that came to my mind and it’s not exactly comparable but it’s not exactly a ringing endorsement of relocation.
