ISIS said they smuggled a missile in do the job. Since, in the year after Obola overthrew the Libiyan government, Egypt was under control of a Mudslime Brotherhood government, also installed by Obola and The Witch, it would have been easy to drive a heavy missile battery across the border for this kind of a mission. Lufthansa made the right decision.

Perhaps a little gun running out of Benghazi is where the missile came from. We could ask Ambassador Stevens but he is dead. We could ask the 30 odd cia operatives at the annex but we have not and will not. WHY?
