For some time one has questioned if Snowden is a naive whistle blower with good intentions or is a sophisticated Russian intelligence operator.
Recent events especially Russian phone and intelligence in the Ukraine support a definite leaning to the latter, intelligence operator.
All that Snowden appearance has done to intelligence types is to push that leaning into the realm of a possible certainty proving almost conclusive proof that the NSA is completely and thoroughly penetrated and compromised.
One way to view his appearance is that the Russians are talking to the Americans and saying covertly with out actually saying it overtly is that "We know every thing you are doing in the Ukraine and every where else in the world".
Assuming, to those of us outside the intelligence community, that our community organizer just got cough with his pants down in what our State Department would call a major Woopsie in attempting to install a more western oriented government in the Ukraine it could be that what the Russians are attempting to do is stop western revolution attempts before this elapses into a more final judgement with mushroom shaped clouds.
