It has been 50 years since the world teetered on the edge of irreparable destruction, when the Cuban missile crisis nearly culminated in Armageddon on the last weekend of October 1962. A quarter century of research on the crisis has given this paper’s authors, James G. Blight and janet M. Lang, a clear understanding of how close the world came to nuclear war. The authors explain that while Armageddon is possible and virtually inevitable, it can be prevented, if a healthy quotient of fear will motivate people to move decisively towards zero nuclear weapons. Blight and Lang argue that using an “Armageddon time machine” to reconstruct the horror of the leaders’ endgame mindsets during the crisis would encourage the world to abolish nuclear weapons.
