Obama wasn’t taking his intel briefings, so who knows if the briefings would have included information about Libya. You must remember that Obama had just, six months prior, deposed the dictator, who was holding down Al Qaeda in Libya. Is the enemy of my enemy my friend?
On top of that, Obama was being pressured by Morsi and the brother of Al Zawahiri, to capitulate to the demands that Bin Laden had set out before the original 9/11 attacks, including the release of all Islamic prisoners ( mainly the Blind Sheik). It would have made an excellent October surprise, if the ambassador had been captured, and Obama had been able to secure his release and appease the Muslim world, by capitulating to the demands laid out by Zawahiri. But something went terribly wrong, the ambassador died.
I’m am with you on this.
