Of course I do. Anyone with the sense of justice should.
The vast majority of the residents of Crimea do not wish to remain as part of Ukraine
I am tiring of repeating this to you. (1) We don't know what the majority wants because the referendum was a farce no campaigning by the pro-Ukrainian side, not even an option to remain in Ukraine on the ballot, foreign occupation and one week to decide that without international observers present. (2) Even if that majority indeed exists after a legally held referendum exposes that fact, Crimea must negotiate it trilaterally and not get war criminals to occupy its territory.
The Soviet Union fell because its political system was steady but not stable, and when the props that supported that steadiness were removed, the system collapsed
Right. It was Reagan's embargo on technological products and the Star War program that caused the "props" for fall. We can do it again.
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.
