Gazeta.pl reports that the majority of the Crimean parliament did not vote in favor of a referendum on independence, but that armed men prevented a quorum from attending, allowing a pro-Russian rump to pass the measure. (For my translation, I am relying on Jacek Rostowski on Twitter.) In eastern Ukraine, pro-Russian crowds face determined Ukrainian nationalist, pro-Maidan forces.
Russia’s military occupation of Crimea should not be taken as evidence of autochthonous secessionism. Instead, Russia seems to be using a minority of secessionist diehards to serve as an excuse for, possibly, annexing Crimea de facto to Russia, in more or less the same way as it did with Abkhazia and South Ossetia after the Russian-Georgian war of 2008. The main differences between that episode and this one are that Abkhazia and South Ossetia had already established de facto independence, and Georgia initiated the conflict with Russia. Thus, Russia’s intervention in Crimea is a riskier gamble. It may indicate, however, just how threatened Russia feels by a future in which Ukraine joins the EU and perhaps even NATO.
Update: TAC’s Dan McCarthy plausibly argues that Russia would prefer to use its military control over Crimea as a bargaining chip to ensure a subservient Ukraine.
