But it's also a CIA-style move as well. Sending in anonymous snipers (esp. those that take out individuals on both sides, not sure if that happened in this case or not) to shoot into government protesters is a tried-and-true tactic from the ol' spook playbook. Always good for helping 'take things up a notch', and perhaps foment an actual revolution ...
And given that CLEARLY the people who are now in charge of Ukraine are far more amenable to Western/EU/NATO/IMF interests than Yanucovych (or however you spell it, he was def. leaning towards the Bear for support), I don't personally see any reason to believe MORE strongly that Putin was behind the snipers anymore than I'd suspect agents from Western Intelligence.
If Europe ends up getting it's NG supply from Russia cut off due to the actions presently afoot, and the USA magically comes to their rescue with it's shiny new terminals shipping away our 'excess' fracked LNG, which is now a political sticking point but may become unstuck if Europe is suddenly in the dark and cold ... let's just say, I'll become even more suspicious w/regards to just who those snipers ... actually were.
In any case, the better informed we become w/regards to who these new leaders actually ARE in Ukraine, the more accurately we can form our opinions with regards to which 'side' we really should be on here. I, for one, was happy to read a 'balancing' piece w/that of Snyder's (which I read earlier in the week), since I honestly don't know WHAT/WHO to actually believe ... but I'm keen to understand what's going on and who the players all are.
