Actually they do have a great degree of control in the new Ukraine government. It’s all out there, just google and read.
They have significant positions of power and authority.
For that reason made it all the easier for Crimea and other areas populated by Russians to resist. Many are more afraid of the New Gov. then they are of Russia....but others are willing to endure till the new elections in May.
Speaking of which they'll be plenty upheaval then to sabotage the elections if it even begins to look like those in power now might loose it. IMO.
