I dont think they created the movement, but they have fed it, as much as maidan was fed by eu.
Either way, it is too late to stop it, the civilians have joined the fray, tons of videos showing that. Even if the first or part of the para-military groups are russian soldiers sent to create dissent, Ukrainian people followed their example and took arms, created barricades in front of local center of power, claiming control of regions.
The only way to stop it, is through internal negotiations, not international policy... Except if they send EU/US/RUS soldiers en masse going in rebelled cities and asking them to surrender. Even that isnt a sure appeasing move.
If everyone keep being stubborn, the only scenarios I see are a counter-maidan (new-new government, or losing territories to Russia again), or a Lybia - Yugoslavia - Vietnam scenario (by order of increased foreign intervention).
