So called WikiLeaks and Julian Assange's efforts to leak huge amounts of US documents only serves to make US look bad, and does nothing really to help the situation.
While I agree that US must have accountability for its actions, much of the leaked documents only serves to embarrass US and allies, and therefore, does not really improve the situation.
In fact, only Western countries would allow such leaks to continue. All the leaks do is destabilize the situation.
I'd be far more impressed if he managed to leak North Korea documents, or Iranian documents. As is, he's just a gossiper who managed to dig up some juicy stuff.
