Let’s even go so far as to say Ambassador Stevens was part of the plot. He helped the Libyan rebels, trusted them, thought they were his friends.
As a gay muslim who had armed many ofthe rebels it is unlikeley but possible that Stevens knew that his “capture” by the daaaastardly rebels was part of the script. And that neat, intended chain of events was overtaken by the fog of the smokey battle that ended up playing out, with Stevens and the others all dying on that well-filmed stage.
There is planning but then there is messy reality also.
The academicians do not understand the sort of people that SEAL training turns those men into.
