My opinion is that no revolution during the past 50 years (and quite probably even earlier) has taken place without some 'assistance' from the outside. Literally - not a single one!
There always have been inspirators who pursued their own interests, and quite often these interests were opposite to what these revolutions had been proclaiming. I don't believe in 'people's sudden self-awareness' and its political will. That's absurd!
Same with Ukraine. Both sides are being manipulated. We're watching a puppet show.
