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.”

Concerns about the credibility of US nuclear deterrence generated Supreme Allied Commander Europe (SACEUR) General Lauris Norstad’s proposal for a NATO-controlled medium-range ballistic missile (MRBM) force. This lengthy report represented INR’s assessment of “present and future European interest in national or multinational nuclear weapons capabilities,” including the MRBM proposal, and the extent to which an “enhancement of NATO's nuclear role” could “deter national or multinational European nuclear weapons programs.”

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.
