I will begin by discussing that latter proposal of yours (made jointly with your student, Kent Wisner).[6] This proposal seems practical to me. Your criterion takes into account delivery vehicles of various throw-weights by assigning them various weight factors. This is very important—the assigning of an equal weight factor to both the small American missiles and the large Soviet missiles was one of the points for which I, at one time, criticized the SALT I Treaty (while in general viewing the very fact of the talks and the concluding of the Treaty in a positive light). Here, in distinction to criteria using the power of the charge, as a rule not published officially, the number of deliverable charges is easy to determine. Your criterion also takes into account the fact that, for example, five missiles each carrying one warhead have a significant tactical advantage over one large missile carrying five warheads. Of course, the criterion you propose does not encompass all the parameters like distance, accuracy, or degree of vulnerability—they will have to be allowed for supplementarily or, in some cases, not taken into account so as to facilitate agreements.
I hope that your (or some analogous) criterion will be accepted as the basis for negotiations both on intercontinental missiles and (independently) on medium-range missiles. In both cases it will be much more difficult than it now is to insist on unfair conditions in the agreements and possible to move from word to deed more swiftly. Most likely, the very acceptance of your (or an analogous) criterion will require a diplomatic and propaganda struggle—but it's worth it.

From this relatively specific question I will move to one more general, more complex and controversial. Is it actually possible when making decisions in the area of nuclear weapons to ignore all the considerations and requirements relevant to the possible scenarios for a nuclear war and simply limit oneself to the criterion of achieving a reliable deterrent—when that criterion is understood to mean an arsenal sufficient to deal a devastating blow in response? Your answer to this question—while perhaps formulating it somewhat differently—is positive and you draw far-reaching conclusions.
There is no doubt that at present the United States already possesses a large number of submarine-based missiles and charges carried by strategic bombers which are not vulnerable to the U.S.S.R. and, in addition, has silo-based missiles though they are smaller than the U.S.S.R.'s—all these in such amounts that, were those charges used against the U.S.S.R., nothing, roughly speaking, would be left of it. You maintain that this has
Your line of reasoning seems to me very strong and convincing. But I think that the concept presented fails to take into account all the complex realities of the opposition that involves two world systems and that there is the necessity (despite your stance) for a more specific and comprehensive unbiased consideration than a simple orientation toward a "reliable deterrent" (in the meaning of the word as formulated above, i.e., the possibility of dealing a devastating retaliatory strike). I will endeavor to explain this statement.
Precisely because an all-out nuclear war means collective suicide, we can imagine that a potential aggressor might count on a lack of resolve on the part of the country under attack to take the step leading to that suicide, i.e., it could count on its victim capitulating for the sake of saving what could be saved. Given that, if the aggressor has a military advantage in some of the variants of conventional warfare or—which is also possible
