Why didn’t they?
A few days ago, I speculated that they might have been able to provide support from Sigonella. Bing West confirms it:
In the past, presidents had taken immediate actions to protect Americans. In 1984, President Reagan had ordered U.S. pilots to force an airliner carrying terrorists to land at Sigonella. Reagan had acted inside a 90-minute window while the aircraft with the terrorists was in the air. The Obama national-security team had several hours in which to move forces from Sigonella to Benghazi.
Fighter jets could have been at Benghazi in an hour; the commandos inside three hours. If the attackers were a mob, as intelligence reported, then an F18 in afterburner, roaring like a lion, would unnerve them. This procedure was applied often in the Iraq and Afghanistan wars. Conversely, if the attackers were terrorists, then the U.S. commandos would eliminate them. But no forces were dispatched from Sigonella.
Someone should ask him why at the debate tonight.
