I'm sure Ukraine has a lot of internal divisions, just like anyone else. I think the one thing that could unity all of them would be the president essentially bending down in front of Putin, grabbing his own ankles, and thanking him after he'd finished. If the American example hadn't been clear enough, this kind of political gaming doesn't work anymore. The internet makes this kind of stuff hard to hide and really difficult to spin if you're looking for your information in multiple sources.
It would take a miracle for the president to step down, but at least, for once, it looks like the police aren't out to kill anyone and the protesters aren't just raising Hell for Hell's sake. Hopefully the government gives in; fair snap elections can't do anything but verify a vote of no-confidence anyway.
The BBC recently had a piece about a protest that happened in the east, in the heart of Yanukovych's power base, where this kind of thing wasn't happening before. Does anyone know how widespread the anti-government sentiment is outside of Kiev?
