A protester in Kiev did an IAmA on Reddit: http://www.reddit.com/r/IAmA/comments/1w17qn/iama_protestor_... According to him, "Russia is trying to keep all the former Soviet Union satellite countries under control, and that is the root cause of the rioting."
Well, it's very popular in Ukraine and kinda nazist point of view, considering Russia as root of all problems. That's why so many nazists amongst "protestors" and why we can have nazi state in Europe if they will take power.
So, I disapprove that point of view, but I have to admit that such neighborhood is a burden for anyone and a source of permanent headache (Pridnestrovye cut off from Moldova, Southern Abhazia separated from Georgia with Russian help, escalation of Armenian-Azerbaijan conflicts, etc). Moreover, Russia in its current Putinist form is a burden for its own people.
