Protesters say they are pro Russia - but in my opinion this is a grave mistake, and Belarus will soon find itself as a Russia-controlled state.
> Moscow offered Minsk economic benefits in December if it complied with a 1999 deal that envisioned a union state with a common currency, legal system and a joint defense and foreign policy.
> The Russian-Belarussian economic confederacy entails the creation of a single tax code, civil code and list of foreign trade rules, in addition to unified oil, gas and electricity market regulators, by 2022, Kommersant reported Monday.

If the protesters said they're against Russian influence, they'd be shot down hard by the Russians (with Lukashenka's assent, obviously) to preserve Belarus as a buffer zone towards the West. If they are pro-Russian / pro-status-quo as far as foreign affairs are concerned, there is at least a (slim) possibility of Putin not keeping Lukashenka in office by any means. But considering previous Russian engagements, it seems extremely unlikely Putin will allow anything other than what he'd consider "stable authoritarianism", because the foreign attachments of a democracy (even a bad one) would be too fluent and thus too risky for him.
