With a nuclear nonproliferation treaty under consideration in Washington, INR considered which countries were likely to sign on and why or why not. INR analysts, mistakenly as it turned out, believed it unlikely that the Soviet Union would be a co-sponsor of a treaty in part because of the “international climate” and also because Moscow and Washington differed on whether a treaty would recognize a “group capability.”

This lengthy report was State Department Bureau of Intelligence and Research's contribution to the first National Intelligence Estimate on the nuclear proliferation, NIE 100-6-57. Written at a time when the United States, the Soviet Union, and the United Kingdom were the only nuclear weapons states, the “Fourth Country” problem referred to the probability that some unspecified country, whether France or China, was likely to be the next nuclear weapons state. Enclosed with letter from Helmut Sonnenfeldt, Division of Research for USSR and Western Europe, to Roger Mateson, 4 June 1957, Secret

The most recent CREST release included this analysis of “The Dynamics of Nuclear Proliferation: Balance of Incentives and Constraints.” The analyst sought to explain why “no additional overt proliferation of nuclear weapons has actually occurred” since the Chinese nuclear test, India had not weaponized while Israel and South Africa had not “taken any action to signal overt possession of nuclear weapons.”

With the term “weapons of mass destruction” having not yet fully come into general usage, this NIE used the term “special weapons” to describe nuclear, biological, and chemical weapons (formerly the term “special weapons” was sometimes used to describe nuclear weapons only). With numerous excisions, including the names of some countries in the sections on “East Asia and the Pacific” and “Central America,” this wide-ranging estimate provides broad-brushed, sometimes superficial, pictures of the situations in numerous countries along with coverage of international controls to halt sensitive technology exports to suspect countries.

This estimate updated an estimate (NIE-4-2-64) published in 1964 of the nuclear proliferation problem. That estimate, like this one, overestimated the likelihood of an Indian bomb, while somewhat underestimating Israel’s program. This assessment followed the same pattern—predicting India would produce a weapon within a “few years” and also putting Israel in the “might” category, although treating it as a “serious contender” nonetheless. Also following a short discussion of the “snowball effect” (later known as “proliferation cascades” or “chains”) suggesting that the United Arab Republic (Egypt-Syria) and Pakistan were likely to take the nuclear option should India or Israel go nuclear.

The State Department writes to Islamabad urging Pakistan to not react if in fact India chooses to launch a nuclear test. On 15 December the New York Times published a story by Tim Weiner, under the headline “US Suspects India Prepares to Conduct Nuclear Test.” While some Indian journalists and policy experts were convinced that the story was a US government plant, Weiner had simply used due diligence in pursuing a lead from a non-government expert on nuclear proliferation issues. Worried that the story would exacerbate regional tensions by encouraging Pakistan to “act in a manner that jeopardizes our nonproliferation efforts in South Asia,” the Department wanted to enlist the Chinese to encourage the Pakistanis to “exercise restraint in response to these reports.”

(Excerpts) Minutes of discussions of the Warsaw Pact Political Consultative Committee concerning non-proliferation. The Romanian delegation argues against a joint declaration of the Warsaw Pact on non-proliferation for fear that it might be used against China. The other delegations argue that a joint declaration is necessary in order to prevent the creation of the Multilaterall Nuclear Force proposed by NATO.
