There was no surprise about the attack. There was no 'failure of intel.' The attack was predicted in precise detail a month before it occurred. The draw down of security had to be intentional.
The failure to approve a rescue had to be intentional.
Keeping the Counterterrorism Security Group (CSG) in the dark about the attack had to be intentional.
Tweeting apologies for the 'anti-Muhammed video' beginning early that morning, repeatedly blaming all the violence at all of our embassies on the 'video' and making an apology video to air in Pakistan had to be intentional.
Stevens presence in Benghazi on 9-11 had to be intentional.

They had real-time onsite video, secured e-mail and were speaking with personnel at both compounds over at least two lines of radio transmission and cell phones. There were two drones overhead. All of that was live-streaming to the entire DoD-DC network of sit-rooms around the world including the White House.
Did Panetta expect al Qaeda to call in with GPS-camera phones and relay their plans and positions to him? Maybe we can air drop laser sighting tags throughout the Muslim world and ask them to all kindly affix one to the tops of their heads? With barcodes so we can target specific jihadis. Oh, and let's require that terrorists submit detailed plans of attacks to a committee for review at least six months in advance.
