According to a Russia analyst friend of mine, Putin may be sending in the "Little Green Men" either today or tomorrow. I'm not sure if they will be doing so to put down the protests and prop up Lukashenka or if they will pull a Crimea and try to install an even more puppety puppet state in place of the previous semi-puppet state.
ISW agrees and has some hard evidence on it: http://www.understandingwar.org/backgrounder/warning-russian-hybrid-intervention-belarus-likely-imminent
Lukashenko did a 180 on the Union State in his rhetoric yesterday; I think it's likely he's folding to Putin for support to stay in power.
I knew it. That's why I was against this "revolution" thing to begin with.
