If I were the CIA I'd be quite pleased for people to know how clever and powerful I am so they don't mess with me. Human assets are rare and precious, but I have no problem flinging a few technological ducats in the general direction of the peasants.

This may or may not be an accurate read of events, but in my view many major 'leaks' of recent years are backdoor propaganda; the State Department Cable archive was embarrassing only if you consider it as a leak, but a really great way to express our government's outlook on a wide variety of topics that would result in conflict if done through formal channels. One can't really know what teh motivations of the people revealing teh information is, and one can imagine many benefits as well as headaches from its release, so it's best not to get too invested in any one one model.

Shhh, look over there. Russians and Julian Assange's agenda! You don't want to weaken the US do you?
