I'm pretty annoyed with Ukraine's actions right now (to put it mildly). By insisting on declaring Crimea "an occupied territory", boosting national anti-Crimea hysteria, and threatening repeatedly with warfare, bans and whatnot it hurts not Russia but Crimeans, who are still Ukrainian citizens according to Ukrainian government.

Crimea is indeed in a very vulnerable position economically and geographically, and this situation should be handled with extreme care. The fact that the government seems to be perfectly willing to destroy it not to "give it away" bothers me.
