The CIA is divided between the Directorate of Intelligence, which houses the analysts, and the Directorate of Operations, which houses the spies and the paramilitary forces. The spies are, in general, divided into two groups. There are those with official cover and those with non-official cover. Official cover means that the agent is working at the U.S. embassy in some country, acting as a cultural, agricultural or some other type of attache, and is protected by diplomatic immunity. They carry out a variety of espionage functions, limited by the fact that most foreign intelligence services know who the CIA agents at the embassy are and, frankly, assume that everyone at the embassy is an agent. They are therefore followed, their home phones are tapped, and their maids deliver scraps of paper to the host government. This obviously limits the utility of these agents. Being seen with one of them automatically blows the cover of any potential recruits.

Then there are those with non-official cover, the NOCs. These agents are the backbone of the American espionage system. A NOC does not have diplomatic cover. If captured, he has no protection. Indeed, as the saying goes, if something goes wrong, the CIA will deny it has ever heard of him. A NOC is under constant pressure when he is needed by the government and is on his own when things go wrong. That is understood going in by all NOCs.

George Friedman of Stratfor on the way the CIA divides up its clandestine staff, and how it relates to the Plame situation.

There is more to this. When it is revealed that you were a NOC, foreign intelligence services begin combing back over your life, examining every relationship you had. Anyone you came into contact with becomes suspect. Sometimes, in some countries, becoming suspect can cost you your life. Revealing the identity of a NOC can be a matter of life and death -- frequently, of people no one has ever heard of or will ever hear of again.

In short, a NOC owes things to his country, and his country owes things to the NOC. We have no idea what Valerie Plame told her family or friends about her work. It may be that she herself broke the rules, revealing that she once worked as a NOC. We can't know that, because we don't know whether she received authorization from the CIA to say things after her own identity was blown by others. She might have been irresponsible, or she might have engaged in damage control. We just don't know.

What we do know is this. In the course of events, reporters contacted two senior officials in the White House -- Rove and Libby. Under the least-damaging scenario we have heard, the reporters already knew that Plame had worked as a NOC. Rove and Libby, at this point, were obligated to say, at the very least, that they could neither confirm nor deny the report. In fact, their duty would have been quite a bit more: Their job was to lie like crazy to mislead the reporters. Rove and Libby had top security clearances and were senior White House officials. It was their sworn duty, undertaken when they accepted their security clearance, to build a "bodyguard of lies" -- in Churchill's phrase -- around the truth concerning U.S. intelligence capabilities.

Why the Plame Affair is far more important than no talent ass clowns like Boortz would have you believe.

[This is something that I've been saying about this since it broke. Outing a CIA agent in the first place is bad. Plame however did no "official" work for CIA, and Rove and/or Libby saying she did was a fundamental breach of National Security. --Mike]
