44 Steps to Armageddon
Herman Kahn wrote “On Escalation: Metaphors and Scenarios” in 1965. It was intended to provide a structure for thinking about the unthinkable-how we could move towards a global nuclear conflict.
If you want more information there is an excellent paper written by Davis and Stan for the Rand Corporation published in 1984.
