The Adultery is a Red Herring. It is a deflection from the cover up. The cover up of Benghazigate is the scandal. This confession and his resignation over charges of adultery is just designed to deflect the nation from the real issues, i.e, just what the hell was Stevens doing in Benghazi and why didn't the CIA, the Military or Obama do anything to rescue him?
Patraeus is hiding something underneath his adultery scandal. Something much more sinister than any sexual affair.
I’ve fairly well convinced myself that Turkey (NATO) was arming the “arab spring” with shoulder-fired anti-aircraft missiles (Manpads), that they lost control of them, that the Americans in Libya were attempting to get them cornered, and they had essentially failed. They knew enough to let everyone know who had put the world’s entire commercial air industry in jeopardy, and they were, therefore, expendable.
Just my personal operating theory.
