I just listened to the entire first segment.
I cannot disagree whole heartedly with Powell. Drawdowns will be necessary, and I believe that they will take place. I also agree with him that the Afghanistan/Pakistan border issue is extremely volitile and serious. A surge there would probably be a good idea while we still have support from the Pakistani government. As Pakistan changes governmental Administrations, our stance may be weakened. We should strike that iron while it is hot in the fire.
However, I do not consider Powell to be a Conservative on most issues, and, while I personally like the guy and have great respect for him, I would not place great emphasis on his political recommendations. And as far as I know, he's been removed from "the know" on military issues for several years now.
Sam Nunn is just a douche.

And I have never been highly impressed with the Aspen Institute.
