That's actually a very well done summary. I have an acquaintance that is Ukrainian and I have been asking her about it. Pretty much what happened so far can be summed up as "The leadership betrayed the Ukrainian people to Russia under pressure from Putin" and both of generally agree that it's too late now to stop, and that the protesters have to be at least partially successful or else it is likely there will be more bloodshed.

Being self designated geopolitics guy though, my curiosity is "Where is the US?" We know they were involved in Georgia in 08, and we know the US has a vested interest in giving the Russians a black eye, so I would think they would be involved somehow, but have not seen as such.
