Follow this link to an article that has a video of General Petraeus making these remarks.
I won’t embed the video here because the interview was on Faux News.
Watching the “news people” discuss the interview after it was all over, I was almost horrified to think that Faux News was actually waking up to reality. By the time the video clip got to the end, my faith in the stupidity of Faux News was abundantly restored.
