Crimea was only part of Ukraine due to Khrushchev making it an administrative part of Ukraine as a political favor to his cronies. Crimea has tried to get out of being part of Ukraine a half dozen times since '91 but until the coup in Ukraine Russia wouldn't take sides on the issue of Crimea leaving the illegal seizure of Crimea from Russia in the first place.
Since the US, the EU, and the UN, all accept the "state" of Kosovo created by brute force and the votes of a half million quickly imported Muzzies, then questioning the right of Crimea to vote to leave Ukraine and become part of Russia is just blatant hypocrisy like the all the other hypocrisy that flows from the Hillybot and Democrap shills (including the democrap shills who pretend they're Republicans, Conservatives, Independents, or anything else).
Spew all the BS you like but people who bother to read and look at the facts know you're either a useful idiot of a paid shill.
@Rashputin Why cherry-pick a specific year? Why not before 1783 when Crimea was part of the Ottoman Empire, or if that year is anathema to you why not pick any other earlier date?
