I guess we'll see if the majority of the residents of Crimea want to be part of Russia. Lets suppose there are scattered and repeated acts of terrorism; lets suppose there is a mass exodus of people voting with their feet to leave the peninsula; or lets suppose there are mass demonstrations protesting Russian control of Crimea - then I'd be willing to concede the point. But until then, the only result we have is the referendum. You've reduced yourself to arguing the issues surrounding the referendum than the results themselves.
War criminals - come on, lets get away from rhetoric.
Stars wars may have played a part but a small one. Regimes generally fall due to three causes: defeat in war, economic paralysis, and political disintegration. All three came together at the fall of the USSR.
It is not a "result" of any kind. It is an exercise of power by the invasion force.
In fact, there was at least once a credible poll there, when Ukraine legitimized the break off of Ukraine, and the Crimeans voted to break off the RF. Not by such a larger margin as the rest of the country, but they did not want to go with Russia then. So the farce that we have to day is not even the "only" anything.
