It occurred before Yanukovych left the Presidency and de-legitimized the Maidan movement and it's collaborators both in and out of Government.
You keep saying CIA initiated. There are lots of theories saying otherwise. In fact, it is surmised the shooters were trying to stoke tensions on both sides and spark violence, with the goal of justifying a Russian invasion. So if you have proof, fine, you believe what you want. I honestly dont know,but dont try to convince me the russian invasions (several over the last 30 years now) are legitimate response to our conducting foreign policy. Honestly, the US has the most pussified foreign policy of any of the super power nations there is. If anything, its weakness inviting Russia to invade, not something we did to threaten them.
