The former diplomats inform PJM the new revelations concentrate in two areas — what Ambassador Chris Stevens was actually doing in Benghazi and the pressure put on General Carter Ham, then in command of U.S. Africa Command (AFRICOM) and therefore responsible for Libya, not to act to protect jeopardized U.S. personnel.
Stevens' mission in Benghazi, they will say, was to buy back Stinger missiles from al-Qaeda groups issued to them by the State Department, not by the CIA. Such a mission would usually be a CIA effort, but the intelligence agency had opposed the idea because of the high risk involved in arming "insurgents" with powerful weapons that endanger civilian aircraft.
Hillary Clinton still wanted to proceed because, in part, as one of the diplomats said, she wanted "to overthrow Gaddafi on the cheap."
This left Stevens in the position of having to clean up the scandalous enterprise when it became clear that the "insurgents" actually were al-Qaeda – indeed, in the view of one of the diplomats, the same group that attacked the consulate and ended up killing Stevens.
And Gen Ham disobeyed orders to stand-down a rescue mission, hence retirment for him.
About the most sense I've read on this tragedy. Truth will be told.
