Obama: Yanukovych then fleeing after WE had brokered a deal to TRANSITION power in Ukraine.
Also he said that Crimea is not a great strategy of Putin
As far as i remember this was after russian sniper teams have turned already violent demonstrations into pure chaos ( :p proof me that i am wrong ).
At this point Yanukovych had only two options, resignation and acceptance of responsibility or the mob drags his body through the streets.
That was the brokered deal.
But then he has chosen the third option and fled to russia.
