Goodbye War looks at some of the causes and consequences of the last two World Wars and of recent small conflicts that have brought us perilously close to nuclear war. As well, it examines why attempts to limit arms and achieve lasting peace have so far failed. Dyer outlines political and international peace initiatives and asks citizens of several nations for their views on war and peace. The series concludes with the warning that we must find a way to say goodbye to war if the human race is to survive.
