This pair of shows doesn't offer the fireworks of some Firing Line debates, but the viewer comes away with a good idea of what the issues are and why this is such an emotional topic. Some samples: Mr. Buckley: "What we have in mind is an act of aggression against the Soviet Union only in the sense that building a roof over our heads is an act of aggression against the rain." Mr. Carter: "This Administration is proceeding at 120 miles an hour on a one-lane road with its lights off at midnight." Mr. Shrum: "This very complex system can never be tested in advance. It has to work perfectly or nearly perfectly in all its components, and it has to work automatically the very first time it's ever used, and it has to do so in a hostile environment and under enemy attack." Mr. Keyworth: "In my opinion, less than one-tenth of one per cent per year of our GNP is a small amount of money to remove us eventually from the scourge of nuclear weapons."
