Again with all these conspiracy theories about Western involvement in Ukraine. The thing about conspiracy theories is that they never hold up when you apply common sense.
There is only one major nation for which the situation in Ukraine is of critical importance: Russia. If EU membership led to a flood of Gean, French, and British investment in Ukrainian oil production, Russia would no longer have a monopoly on oil exports to the rest of Europe. This would be a disaster for the Russian oil oligarchs that keep Putin in power. From the perspective of EU businessmen, however, it matters little whether they invest in Ukraine or Russia. Meanwhile, the average American probably wouldn't even be able to point Ukraine out on a map.
So who has the vested interest in interfering in Ukrainian politics? Moreover, who has a history of interfering in Ukrainian politics? That's right, Russia. Are you forgetting that the KGB tried to assassinate Yushchenko in 2014? Of course Russia and their lackey Yanukovych claimed that Yushchenko poisoined and nearly killed himself to win sympathy from voters, because that is something that a sane person would do. (Note the heavy sarcasm.)
So no, the protests in Kiev were not engineered by the CIA; they were grassroots. Just because you read it on RIA Novosti, doesn't make it true.
