@maxdancona,
Crimea has belonged to Russia for centuries. Khruschev put it under Ukrainian control in 53 as an administrative measure and ownership did not matter at that time since everybody was soviet citizens one way or other but, clearly, ownership DOES matter after the collapse of the CCCP.
What has happened recently is that Bork Obunga, George Soros, Victoria Nuland and the rest of our rogue state department managed to engineer an overthrow of a legitimately elected government in Kiev and the Eastern side of Ukraine which is largely Russian speaking wants no part of the new Kiev government which is basically a bunch of unreconstructed bandaristas and nazis, but Particularly Crimea wanted no part of that. They voted to leave the illegitimate new Kiev state and then rejoin Russia, both votes by upwards of 90% of the electorate.
