The Crimean people do not want to live under Ukrainian rule. That was clear from the referenda in 1991, 1994 and 2014. Don't pretend that Kiev can turn the clock back and resubjugate Crimea. It won't work.
@StephenKing It bears repeating --- only the people of Crimea and Donbass have the right to determine their own future. The will of the people can be tested any time by referendum, hence the need for the UN to organize referenda.
