On 3-4 November 2021, on the heels of the 30th anniversary of the 1991 Madrid Conference, the James Martin Center for Nonproliferation Studies (CNS) and the Nuclear Proliferation International History Project (NPIHP) at the Wilson Center hosted a virtual roundtable as part of their 1990s Arms Control and Regional Security (ACRS) Working Group oral history project. The event convened around 20 former ACRS delegates from key regional and extra-regional states for an in-depth exchange on their personal recollections from the ACRS process. In four sessions, which were conducted virtually over two days, participants revisited: the genesis of ACRS; the format and process of the ACRS Working Group; fault lines and inflection points during ACRS; and its successes, failures, and lessons learnt from the process.

Canadian officials warned of disagreement to come between the Europeans and the Americans over the “zero option,” the longstanding proposal to reduce both US and Soviet INF to zero. This dispatch from Brussels reported “substantial unhappiness” amongst the Europeans that the United States and the Soviet Union would discuss disarmament “even if neither of them believed in it.” Nuclear deterrence had prevented war in Europe for the preceding four decades, and US-Soviet discussions of disarmament only made it even more difficult to convince public opinion of deterrence’s continued importance

Despite new information that the Soviet Union was deploying anti-ballistic missile defenses around Moscow, the United States had not yet decided to deploy its own ABM defenses (although a decision would be made later in the year) and there was some hope that U.S.-Soviet talks would prevent an ABM race. If, however, talks failed, some NATO allies worried about the “adverse consequences” of an ABM race, especially whether having an ABM system might incline Washington toward risk taking.

In their final talk, Trudeau and Zhou Enlai discuss Sino-Canadian trade, the Cultural Revolution, and the status of Chinese in Canada.

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 describes the meeting of 15 nuclear supplier states in London where issues were discussed such as full-scope safeguards, including sanctions in the guidelines, purpose of supplier consent, moratoriums, enlargement of membership, and various countries' individual concerns were voiced and addressed.

This telegram describes what the nuclear suppliers' countries accomplished during their November 11-12 meeting. Continued discussions of safeguards and enlarging the group, and agreed that they would wait on publishing results until after their next meeting, which was scheduled to be the following March in London.

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.

In this document regarding the final agreement, George Vest wrote Kissinger that it “served to close many of the loopholes and inadequacies of previous nuclear cooperation agreements between suppliers and recipients.” It also put the French and West Germans on record to restrict access to sensitive nuclear technologies. Nevertheless, as Vest noted, the guidelines would not prevent “indigenous” development of nuclear capabilities and “unsafeguarded developments” or the acquisition of sensitive technology.
