He hasn't done it on that magnitude. With Syria or whatever there were voices within the system that backed a small footprint but Assange has no one. He would be letting a person off the hook that as far as he knows is a Russian spy. I mean he could do it in his second term if he felt like it since the history books are written by communists anyway but it's not clear what he himself thinks. There's a decent chance that he believes the intelligence agencies and the military.
