Believe me, I am well aware of CIA history, although I believe there is a tendency for some to overestimate what the CIA can do. For them to overthrow a government, there has to be a significant amount of people that already want such a thing. The CIA can help and assist, but control is an illusion. And the modern day version of the KGB has significantly more influence in that region than we do.

On March 5, a phone call between Estonia’s Foreign Minister Urmas Paet and EU foreign affairs chief Catherine Ashton was leaked online. Regarding the sniper attacks, Paet says:
“What was quite disturbing, this same Olga told as well that all the evidence shows that the people who were killed by snipers from both sides, among policemen, and then people from the streets, that they were the same snipers killing people from both sides.”
“She then also showed me some photos she said that as a medical doctor she can say that it is the same handwriting, the same type of bullets, and it’s really disturbing that now the new coalition, that they don’t want to investigate what exactly happened.”
“There is now stronger and stronger understanding that behind the snipers, it was not Yanukovich, but it was somebody from the new coalition.”
“It already discredits from the very beginning this new coalition.”
The US really doesn't gain much, other than watching Russia founder a bit.
In the short term. In the near term they get the oil fields in Crimea (which are rich, and to this point relatively untapped). And in the long term, they get all of Russia's oil fields AND control of the flow of oil to Europe.
