I already posted this above:
Something else to keep in mind, is the area under dispute. The Autonomous Republic of Crimea. See, it's not exactly "Ukrainian" at all. It is an autonomous republic. The demographics? 50% Russian, 25% Ukrainian, and the balance are mostly Tatars. How and when did Crimea become "Ukrainian" anyway? Oh - that was an administrative move, made by the old Soviet, which stuck Crimea in with the Ukraine. Administrative. Crimea never has been "Ukrainian". So, if an AUTONOMOUS Republic wishes to remove itself from association with a nation that only has administrative ties to it - why not?
I stand with Crimea and Russia on this issue. The current regime in the Ukraine are a bunch of racist assholes. Among their first actions upon assuming power, was to outlaw the Russian language in any formal or official documents. Crimeans speak Russian, not Ukrainian. Screw the president, and screw the capital - Crimeans decided that they don't want to be "Ukrainian" any longer.
Not very many nations are willing to assist another nation in the suppression of an AUTONOMOUS REPUBLIC.
