Edward Teller, a nuclear physicist and key figure in Oppenheimer, and Sidney Drell, a nuclear arms control expert, debate the necessity and regulations of nuclear weapons in the late 20th century. They discuss President Reagan's defense systems proposal, the wastefulness of his defense program, and the complexities of developing and implementing a defense system. Former CIA Director James Woolsey joins them to emphasize the importance of missile defense against threats to allies and terrorism.
