I have always been quite skeptical of BHO’s claim that he went to Pakistan in the 80’s. I have been under the impression that this event wasn’t in his books (which I have never read), and had never been mentioned before he brought it up during the Presidential race.
My take was that he simply made it up as a desperate attempt to try and provide some kind of thin veneer of foreign policy experience.
