Even though it is the ultimate in Type I Deterrence, the Doomsday Machine is an unsatisfactory basis for a weapon system. It is most improbable that … - Herman Kahn

The Russians aren't dedicated world dominationists. You know, they just sort of want it on account of a sentimental way, you know, but not like 'By God, we got to have it!' It just doesn't make sense for them to really push too hard, you know, but just to push easy.

He flips to a drawing of a spindly boy wearing oversized glasses, hugging an ABC primer, and sniffing a daisy. This is the enemy. " The first [mistake] is to assume that he is a sort of cretinoid idiot, who can't see, think, or anything. It might be a fair, if dangerous, assumption that the enemy is at least as stupid as we are."

However, even those who expect deterrence to work might hesitate at introducing a new weapon system that increased the reliability of deterrence, but at the cost of increasing the possible casualties by a factor of 10, that is, there would then be one or two billion hostages at risk if their expectations fail. Neither the 180 million Americans nor even the half billion people in the NATO alliance should or would be willing to design and procure a security system in which a malfunction or failure would cause the death of one or two billion people. If the choice were made explicit, the United States or NATO would seriously consider "lower quality" systems; i.e.,systems which were less deterring, but whose consequences were less catastrophic if deterrence failed. They would even consider such possibilities as a dangerous degree of partial or complete unilateral disarmament, if there were no other acceptable postures. The West might be willing to procure a military system which, if used in a totally irrational and unrealistic way, could cause such damage, but only if all of the normal or practically conceivable abnormal ways of operating the system would not do anything like the hypothesized damage. On the other hand, we would not let the Soviets cynically blackmail us into accommodation by a threat on their part to build a Doomsday Machine, even though we would not consciously build a strategic system which inevitably forced the Soviets to build a Doomsday Machine in self-defense.
