What I don't believe is that the Ukranian protests could get so violent and so effective without outside help. Add to that the indisputable fact that Nuland made a friendly visit to the protestors. Then there's the situation that all of these protests since Obama took office have had CIA or other foreign involvement.
The other thing to keep in mind wrt Putin and computer hackers is that Putin himself is primarily responsible for the fact that the world's economies have not yet been sacrificed to Gaea by the green/Malthusian lunatics. Putin apparently got a number of Russia's best hackers in a room and said something like "Guys, I'm not gonna **** Russia's economyt over a bunch of BS, I want you to blast your way into that East Anglia email database and spread to the four winds whatever you might happen to find there." That was the basis for Climategate (www.climategate.com).
