You guess wrong as so many ARRSERs do who assume far too much in terms of "knowing" me. I think Hilary is the responsible official and the He should have already asked for her resignation. In that since yes indeed He is responsible.
I find your apparently partisan assumption rather tawdry under the circumstances of the needless brutal murders of 4 of my countrymen.. In case you missed it, I try to view the delicts of our politicians with a broader perspective than base partisan concerns and am on record as having been critical of many of both parties, including even the mighty Reagan who I hold responsible as Commander in Chief for the nearly 300 Marines, sailors and soldiers sacrificed in Beirut in 1983. I hold Clinton responsible for the horrific deaths of US SF operators and air crew in Mogadishu for the failure to reinforce the force as requested by the on-scene commander.
Similarly, had the 4 murdered in Benghazi been serving military I would have also hold Him responsible.
I am of the old school that a commander is (ultimately) responsible for EVERYTHING your subordinates do or fail to do.
