Actualy our inventory of F-111s has been emptied. Only the Aussies still fly the aircraft. Some, but not all, of theirs are ex USAF. However we have replaced the F-111s with the F-15E. They stand ready, along with Navy F-14s now converted to "Bomb Cats", to address any problems Qadaffi might want to create. Then there are the F-117s, B-2s and the always popular, middle aged, B-52.
Plus, I'm sure we still have one or two Daisy-cutters lying around somewhere.
