The "not optimal" comment goes to a rumor I saw last week that the Benghazi fiasco was actually the first stage of a plot to kidnap (not kill) Ambassador Stephens and then exchange the Blind Sheik for him just prior to the election as another great Obama victory. The two Navy seals just happened to be in Benghazi and joined in the fight when they witnessed the attack. It was thought that the rebels were incensed that they met with resistance and tortured and murdered Stephens in retaliation. The Obama administration had no choice but to cover up the failed plot with the video ruse, but they got caught up in the lie.
It makes for good drama, and it does track well with the known facts, doesn't it?
