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.”

Zhou Enlai and Trudeau have a wideranging conversation on international politics, covering the Vietnam War, Sino-Japanese relations, Nixon's visit to China, the Arab-Israeli conflict, the Arctic circle, and nuclear energy safeguards, among other topics.

This document provides an overview of the London Nuclear Suppliers' Meeting which included the addition of the five newest countries to the original seven. Most old and new members were receptive when Washington lobbied them to support a “long term and stable regime of restraint” on the export of sensitive enrichment and reprocessing technology. While the French were supportive of the moratorium proposal, the Germans were uncomfortable with it, not least because of the implications for their deal with Brazil.

This document describes the differing views regarding safeguards. The Canadians strongly supported the former, “full scope safeguards” (their terminology, which caught on), which the French saw as “tantamount to imposing NPT obligations”--a reference to the Treaty’s Article III--which they would not accept. Arguing that full-scope safeguards was “alien to [their] philosophy,” the French suggested that a “traditional interpretation of the contamination principle (i.e., requiring safeguards on any materials produced in exported facilities),” would make it possible to achieve “the practical equivalent” of the Canadian proposal.

In the course of a background paper on the nuclear proliferation problem and policy options, the State Department updated the White House on the state of play of the nuclear suppliers’ initiative: the British, the Canadians, and the Soviets had agreed to attend a meeting; the Germans would agree “if all key suppliers” (France) accepted; and the Japanese, who had also been asked, had not responded. The French had not given an answer and bilateral discussions would take place to go over the issues.

This US analysis of the likelihood of nuclear proliferation during the next decade was finished only days after the first Chinese nuclear test on 16 October. The report analyses the implications of this test, as well as programs in India, Israel, Sweden, West Germany, Italy, Japan, Canada, and others. The National Intelligence Estimate (NIE) argued that India was the only new state likely to develop nuclear weapons, concluding that “there will not be a widespread proliferation …over the next decade.”
