Thirty years ago, Pierre Sprey (left) was, like John Boyd and Chuck Spinney, one of the protagonists of my book National Defense. He is a great, innovative thinker who is always worth listening to, and tonight on C-Span he hosts an interview with William Hartung, about Hartung's book Prophets of War. Airing at 9pm Eastern; full schedule here. Very much worth checking out (or setting your TiVo for).
