Bruce Kent, ordained a Catholic minister in 1958, became general secretary of the Campaign for Nuclear Disarmament (CND) in 1980 and chairman in 1987, the year he resigned from the ministry. In this video segment, he challenges the damaging spin that secretary for defense Lord Michael Heseltine used to undermine CND rather than engage in public debate about nuclear policy. Kent also refutes accusations that CND was in support of 'one-sided,' full unilateral disarmament. Instead, he argues for 'sufficiency' to replace 'parity' of nuclear forces. In the interview Kent conducted for War and Peace in the Nuclear Age: 'Zero Hour,' he describes the forces that converged to revive CND and the rallies that drew hundreds of thousands of marchers to the center of London in the early 1980s. He recounts the spread of peace movements to other Western European capitals, the partnership among protest leaders from these other countries, and some of the differences in their national agendas. The 1983 Conservative Party's rise to power on the heels of the Falklands War, coupled with its forceful campaign to mischaracterize CND, halted the movement's momentum. At this point, Kent recalls, CND shifted its agenda to 'the long haul,' prioritizing long-term, international public education over large demonstrations. Kent critiques 'flexible response' what he calls 'the Achilles' heel' of the Western alliance. Nuclear war is so clearly unwinnable, he maintains, that 'parity' must yield to 'sufficiency.' As Kent sees positions like these echoed in public discourse and arms negotiations, he concludes that CND's key contribution is helping 'some serious rethinking of the basics of the whole business.'

Alain Enthoven, an MIT economist, was the country's first assistant secretary of defense for systems analysis from 1965 to 1969. In this video segment, Enthoven recounts how public interpretation of 'flexible response' strategy ran counter to both the administration's overriding goal-to prevent nuclear war-and its bottom line: that nuclear war is unwinnable. In his interview conducted for War and Peace in the Nuclear Age: 'The Education of Robert McNamara,' Enthoven sets the stage for the missile age. He discusses how the arrival of nuclear weapons that could reach the United States made it necessary to rethink military strategy and the nation's overall defense posture. What was new, he points out, was the establishment of systems analysis for making key decisions on force requirements, weapon systems, targeting theory, and other military matters. He recalls that dismissing 'massive retaliation' and the untenable consequences it posed, canceling an array of bomber and ballistic programs, and focusing on a conventional military buildup and a survivable retaliatory force generated immense controversy among U.S. military circles and European partners in the North Atlantic Treaty Organization (NATO).

For nearly half a century, Paul Nitze was one of the chief architects of U.S. policy toward the Soviet Union. In 1961, President John F. Kennedy appointed Nitze assistant secretary of defense for International Security Affairs. In this video segment, Nitze describes key issues confronting the incoming Kennedy administration. This transition period focused on the goals of the country's nuclear-strategic policy; how to approach crises in every region, from the Middle East to Vietnam; and whether to unify the armed services. Included are Nitze's recommendations regarding a conventional military buildup and a 'no-cities' policy, which would target military forces instead of civilian populations. Nitze's interview conducted for War and Peace in the Nuclear Age: 'At the Brink' moves the viewer through his work with the World War II Strategic Bombing Survey, which placed him in Hiroshima and Nagasaki soon after the atomic bombs were dropped. From 1950 to 1953, Nitze served as director of the State Department's Policy Planning staff, and from 1961 to 1963 he was assistant defense secretary. As his interview reveals, Nitze held key positions during the period after World War II when the United States emerged as a superpower and Cold War strategic policies were being debated and defined. His classified 1950 report, National Security Memorandum 68, remains a seminal document: it was initially designed to persuade President Harry S. Truman that an increasingly menacing world required major increases in spending on defense and foreign military assistance. Nitze was also a major contributor to the Gaither Report, which stressed the need for a survivable nuclear deterrent by citing the vulnerability of the U.S. bomber force. Nitze opposed the doctrine of massive retaliation from the moment John Foster Dulles announced it at a dinner party in 1954. He was involved in crisis contingency planning, including the Berlin blockade and airlift in 1948, construction of the Berlin Wall in 1961, and the Cuban missile crisis in 1962. During the missile crisis, Nitze recalls, he worked out the scenarios of increasing military escalation to pressure the Soviets to withdraw the missiles. Finally, he describes his disappointment that, although Secretary of Defense Robert McNamara initially embraced his no-cities strategy, following the Cuban missile crisis McNamara entirely abandoned the notion of winnable nuclear war.
