I am surprised Senator McCain has been aggressive toward the current president in the matter of the attack on the diplomats in LIbya. There is some similarity between this controversy and the attack on the USS Liberty many years ago: was the attack deliberate, why didn't we protect our people, what's being covered up. Senator McCain's father, a great Navy hero, was in command of the fleet to which the Liberty belonged. For years Senator McCain and his father have been unfairly abused by those unhappy with the answers the Navy and the government have tried to provide.  Yet McCain rushes to give President Obama the same treatment.
