If you support Ukraine overturning an elected government, you have to also support the Crimea Parliament voting to go independent. And yes, they will have a referendum on March 16 allowing voters to decide on joining Russia. I’m guessing the vote will be overwhelming yes.
Thus, Crimea may leave Ukraine and it will be done with a surprising lack of violence. And it will be done democratically.
When Slovakia voted to split from Czechoslovakia, Premier Vaclac Havel said “I don’t think it’s a good idea. But they voted for it. Let them go.” Will the US / EU allow a similar split without violence or “intervening”?
