Obama could have and should have granted CBA. In under 2 hours from the first attack, F-16s would have been strafing the borders of the consulate, rotating in from Sigonella after their first flight from Aviano.
Shortly after, Spectre gunships from Sigonella would have been on station to blast the holy hell out of any attackers who got within a kilometer of the consulate. The Ambassador would have been saved, and the secret annex would have probably been kept secret.
But Obama hid like a dirty coward to avoid being pinned down to grant or deny CBA.
Your comments on this matter have been amazing to read. Thank you for your service to our country, Sir.
