I just finished reading 'A Canticle for Leibowitz', it was written in the 1960's and is about the aftermath of a full on nuclear war. The science is dated, but still.. nuclear weapons are amazingly destructive. The though of myriads of little states with their own agendas chills me. I dunno, I really think somebody needs to play daddy in the world. The best case is if we could go multilateral.
