The video was a factor but anyone who doesn't recognize the significance of the date of the attack is a fucking moron. No doubt the 9/11 attack was planned in advance.
IMO, the CIA was running an op to collect small arms from Libya and ship them to secular rebels in Syria. Obama would have known about it as well as his ambassador...which would explain why Stevens was there instead of the more secure embassy in Tripoli. Hillary, paranoid about evidence, excluded herself from the classified email traffic loop probably didn't know about it unless a staffer told her.

- Tripoli: government appointed by the old parliament that challenged the legitimacy of last year's elections
- Tobruk: internationally recognised government that was ousted from the capital not long after the 2014 election
- Both backed by a loose alliance of militias focused on local interests
- Benghazi: the second city and headquarters of the 2011 Revolution, is largely in the hands of Islamist fighters, some with links to al-Qaeda
- Misrata: the third city and main port, is also loyal to the Tripoli authorities. Its militias keep them in power.
