If? If??
It has been obvious from the beginning that he was being blackmailed.
Maybe we should go back and parse his statements from that time period and see if there are any little hints in his language.
Yes.... but not over his 'affair' with Paula. Once you let the 'secret' out, it's power is used up.
Besides, it was only the 'public' that didn't know about it. Everyone around him knew. I would also expect that if we checked, just about every 'on the road' military commander has some 'hottie' staff member that likes to cozy up to them.
Exposing the Paula affair was done to divert the public away from the real reason he resigned (meaning... told to quit or else).
I would love to see Petraeus testify in an upcoming hearing, and say these exact words: "I was being blackmailed by Hillary Clinton." The media would never be able to ignore a statement like that.
