Denis Healey was the British secretary of state for defense from 1964 to 1970 and chancellor of the exchequer from 1974 to 1979. In this video segment, Healey reflects on the period in which he was defense secretary under Prime Minister Harold Wilson. He recalls the opposing interests of Germany and the United States with regard to nuclear strategy, explains his 'Healey theorem' of deterrence, and clarifies France's position that alliances can't coexist with nuclear weapons. Healey also assesses U.S. defense secretary Robert McNamara's quest for tidy solutions to 'insoluble' nuclear problems. In his interview conducted for War and Peace in the Nuclear Age: 'The Education of Robert McNamara,' Healey begins with a comparison between Soviet and North Atlantic Treaty Organization (NATO) conventional military strength. He elaborates on France's opposition to the notion of 'extended deterrence' and on his own role in persuading NATO to adopt 'flexible response' strategy. He traces the evolution of his military analysis of massive retaliation, describes his collaboration with McNamara in developing flexible-response doctrine, reiterates the expectation that SALT III would follow shortly after a ratified SALT II Treaty, and shares how he ultimately lost faith in flexible response. He also discusses the extraordinary growth of U.S. tactical nuclear weapons in Europe, Britain's response to the proposal for a Multilateral Force in the early 1960s, German chancellor Helmut Schmidt's distrust of U.S. president Jimmy Carter, and his own opposition to U.S. Euro-strategic missiles. As a fellow defense intellectual, Healey was encouraged by national security adviser Henry Kissinger's appointment: he was sure that detente could move forward. He admired Kissinger's boldness in dodging 'all official channels which he doesn't like anybody else doing,' but he was disappointed by Kissinger's failure to consult with allies. For the future, Healey believes that there should be fifty-percent reductions in strategic and conventional weapons, particularly when 'one side or the other has superiority.' He also advocates a 'nuclear-free corridor' to avoid accidental war.

Chandra Shekhar Jha was India's foreign secretary from 1965 to 1967. In this video segment, Jha explains why India cannot exclude the future possibility of owning nuclear weapons. The key to disarmament, he insists, rests with the nuclear nations that are 'adding to their stockpiles' and 'preparing for war. 'Jha's interview conducted for War and Peace in the Nuclear Age: 'The Haves and Have-Nots' begins with his recollections of his devastating post-war tour of Japan with Prime Minister Jawaharlal Nehru and their shared ideals of disarmament and economic development by harnessing 'Atoms for Peace.' Jha's interview also examines the dilemma of staying the non-nuclear course given regional security concerns: the 1962 Chinese attack on India, followed two years later by China's detonation of its first nuclear bomb, and ongoing tensions with its neighbor Pakistan. While prioritizing the country's economic development over diverting resources to acquire nuclear weapons, Jha rejects the Non-Proliferation Treaty as embodying 'nuclear colonialism' and objects to the preferential treatment granted other threshold states.

At age twenty-seven, physicist Philip Morrison joined the Manhattan Project, the code name given to the U.S. government's covert effort at Los Alamos to develop the first nuclear weapon. The Manhattan Project was also the most expensive single program ever financed by public funds. In this video segment, Morrison describes the charismatic leadership of his mentor, J. Robert Oppenheimer, and the urgency of their mission to manufacture a weapon 'which if we didn't make first would lead to the loss of the war." In the interview Morrison conducted for War and Peace in the Nuclear Age: 'Dawn,' he describes the remote, inaccessible setting of the laboratory that operated in extreme secrecy. It was this physical isolation, he maintains, that allowed scientists extraordinary freedom to exchange ideas with fellow physicists. Morrison also reflects on his wartime fears. Germany had many of the greatest minds in physics and engineering, which created tremendous anxiety among Allied scientists that it would win the atomic race and the war, and Morrison recalls the elaborate schemes he devised to determine that country's atomic progress. At the time that he was helping assemble the world's first atomic bomb, Morrison believed that nuclear weapons 'could be made part of the construction of the peace.' A month after the war, he toured Hiroshima, and for several years thereafter he testified, became a public spokesman, and lobbied for international nuclear cooperation. After leaving Los Alamos, Morrison returned to academia. For the rest of his life he was a forceful voice against nuclear weapons.

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.

Dean Rusk came from barefoot poverty in rural Georgia and achieved black-tie success. He was the first assistant secretary for UN Affairs, in 1949; assistant secretary of state for Far Eastern Affairs, in 1950; and the country's second-longest-serving secretary of state (1961 to 1969), after Cordell Hull. In this video segment, Rusk voices his opposition to the Strategic Defense Initiative, commonly known as 'Star Wars' and first unveiled in March 1983. In his interview conducted for War and Peace in the Nuclear Age: 'Visions of War and Peace,' Rusk reflects on a wide range of political and nuclear issues spanning more than forty years. He discusses his recognition that the first atomic bomb introduced a 'new phase of warfare'; his opinion that Soviet premier Joseph Stalin's 'adventures' spawned the Cold War and the United States' 'containment' policy; how the past three decades created a vastly different diplomatic landscape against which to conduct foreign relations; and the urgency of domestic problems that threaten national security. Although known throughout his career for his hawkish views, in 'Visions of War and Peace' Rusk turns again and again to the dominant lesson of the nuclear age: nuclear war is 'simply that war which must never be fought.'
