Bizarre.
Kiev is supposed to be the cradle of Rus' (not good news for the Ukrainians).
Crimea is Russia's Miami maybe.
It's more like the relationship between England and the United States, except if the United States was dominated by Mongols and had a long tradition of oriental despotism (Kiev had one of the earliest constitutions). When Moscow was still wilderness, Kiev already had its own civilization. The King who was baptized in Crimea was a Kievan King, not a Muscovite.
The only claim that Russia has over Crimea is a long history of conquest, occupation, colonization, rape and murder of whoever happened to be living there.
