Conspiracy, negligence, ideology, and incompetence aren't mutually exclusive. I don't buy the idea that Benghazi was set up to let Obama trade the captured ambassasdor for the Blind Sheik. But that doesn't exhaust the list of conspiracies. I tend to think that an attempt at gathering the arms we'd given the Libyan rebels -- either to send those arms to Syria or just to get them warehoused before they could be linked to American deaths -- blew up in the regime's face. But I can easily believe that Hillary set it up to sabotage Obama's political ambitions (or vice versa). Or that the regime let its own people die to preserve the often-told lie that Al Qaeda is moribund and the Middle East is moderating.
