I have been googgling, trying to find out why Crimea was seceded to Ukraine in the first place, having been part of Russia for many years previously. It seems that there were many horrors committed there as in the rest of the then Soviet Union. Khrushchev's wife was Ukrainian, he himself was half Ukrainian, and had worked in the Ukrainian mines as a young man, had an affinity with Ukraine, and gifted them the Crimea. Obviously Khrushchev could not have possibly contemplated the breakup of the Soviet Union, and while this was still in place, all was well. BUT after the collapse of the USSR, Crimea, a good proportion of whom are ethnic Russians. was a focal point for trouble the moment it turned its eyes to the West, so to speak. This in no way excuses Putin for over running this peninsular, as treaties made in 1954 must be valid today. Best thing would have been a referendum for Crimea, but clearly it's a bit late for that.
