Continuing the topic of Col. Harry G. Summers, I recommend the interview he did with U.C. Berkeley’s Conversations with History television program, which is inserted below. The video is nearly an hour long and over a decade old but if you have time to spare it’s definitely worth watching.
Conversations with History is probably the best interview series that I’m aware of. Be sure to check out their website and their Youtube uploads for interviews with many other prominent guests.
