There is some controversy over the damage Snowden did but given how easily he was able to pull off what he was able to do, every spy agency in the world had been there before. The American intelligence networks are as open as a pubic library. The rest of the world taps into anything they want. Secrecy to our enemies is nil. The only people this vast network of domestic espionage was unknown to were we citizens of the West. The startling part about the entire story was how someone like Snowden could penetrate the system in the way he did and download what he was able. If you think the Russians, the Chinese and the Iranians had not been there before, you are as blind to the incompetence of the American bureaucratic establishment as it is possible to be.
