"The unacceptability of the Doomsday Machine raises awkward, unpleasant, and complicated questions that must be considered by both policy maker and technician. If it is not acceptable to risk the lives of the three billion inhabitants of the earth in order to protect ourselves from surprise attack, then how many people would we be willing to risk? I believe that both the United States and NATO would reluctantly be willing to envisage the possibility of one or two hundred million people dying from the immediate effects, even if one does not include deferred long-term effects due to radiation, if an all-out thermonuclear war results from a failure of Type I Deterrence. With somewhat more controversy, similar numbers would apply to Type II Deterrence. We are willing to live with the possibility partly because we think of it as a remote possibility. We do not expect either kind of deterrence to fail, and we do not expect the results to be that cataclysmic if deterrence does fail."

“The final outcome of benevolent, informed, and intelligent decisions may turn out to be disastrous. But choices must be made; dies must be cast.”

“The usual image of war today held by many experts as well as most laymen can be summed up in the phrase "orgiastic spasm of destruction," or, "spasm war." Many believe that if one single button is pressed all the buttons will be pressed, and that some 30 minutes or so later missiles will rain enough destruction to terminate the defender's existence as a nation; subsequently, some minutes or hours later, a similar rain of death and destruction will annihilate the attacking nation. Within perhaps an hour or two the war will be effectively over-both combatants having received death blows-with only one question left; "How bad will the radiation be for the rest of the world?”

“We must not look too dangerous to neutrals. While this is probably less important for us than not looking too dangerous to friends and allies, it is still too important to be ignored. Here again, we must not look excessively destructive. It may be all right to promise the Soviets that if they attack us we will destroy every Soviet citizen in retaliation , but we should not threaten nonbelligerents with near annihilation because of our quarrel with the Russians. Many of the world's inhabitant perhaps two-thirds of them, do not feel it is their quarrel but feel it is their world. The more destructive we look, the less they like us and our program. To the extent that some in our midst talk and threaten potential world annihilation as a U.S. defense measure, we focus undeserved attention on ourselves as being dangerous and even irresponsible—appearing to be willing to risk uncounted hundreds of millions or billions of bystanders as to our selfish ambitions and desires. Neutrals and bystanders will inevitably suffer heavily in any thermonuclear War. But there is a difference between damage and annihilation.”

“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.”

“The easiest way in which one can put unintentional strains on the enemy is to have a force which looks "trigger-happy." The one circumstance under which almost all Soviet experts agree the Russians might strike is the one in which they feel they are anticipating a strike by us. It will be difficult for them to read our intentions. They will doubtless err on the side of caution. But it is not clear which side will look cautious, particularly if there is a crisis which creates apprehension. It will add a real element of stability if our posture is such that we do not look as if we have to be "trigger-happy" in order to survive. This is an important reason for not relying solely on quick reaction as a protection and for not having forces so vulnerable that we could lose most of them from a Russian first strike. Under some circumstances our vulnerability to a Russian first strike would both tempt the Russians to initiate a war and at the same time compel them, because they might feel that we would be tempted to pre empt for our own protection. If we are sufficiently vulnerable they might find it impossible to believe that we were willing, in this crisis to rely on their good will, morality; caution, or sense of responsibility as a protection.”

“As far as patriots and nationalists are concerned, I believe that the Homicide Pact system has many of the same drawbacks as the Doomsday Machine, though not in so extreme a form.The major advantage of the Homicide Pact is that one is not in the bizarre situation of being killed with his own equipment; while intellectuals may not so distinguish, the policy makers and practical men prefer being killed by the other side. It is just because this view no longer strikes some people as bizarre that it is so dangerous.”
