It was wonderful to see Russia take one on the nose when the corrupt, pro-Russian President was sent packing. However, the reality of the ethnic mix in the Ukraine means that the Eastern side of the mainland and Crimea are not a natural fit for Ukraine.
Ceding that territory or turning it into one or two quasi states would be painful but far better than having a full scale war or an ongoing civil war.
Rebuilding a smaller but ethnically more homogeneous Ukraine should be the focus of the West’s efforts. And, realistically, that is about all the West has the capacity to do in any event.
