" This seminar examines the history and legacy of the Cold War on American science. It explores scientist's new political roles after World War II, ranging from elite policy makers in the nuclear age to victims of domestic anti Communism. It also examines the changing institutions in which the physical sciences and social sciences were conducted during the postwar decades, investigating possible epistemic effects on forms of knowledge. The subject closes by considering the place of science in the post-Cold War era."

General Gerd Schmuckle served in the Federal Republic of Germany's Ministry of Defense from 1956 to 1962 under defense minister Franz Josef Strauss. Strauss was charged with building up the Bundeswehr, the newly formed federal armed forces. In this video segment, Schmuckle describes Germany's reaction to the U.S. doctrine of massive retaliation, which de-emphasized a conventional buildup-one that Germans advocated-and depended on thousands of nuclear warheads deployed on German soil. When French president Charles de Gaulle returned to power in 1958, his main concern-developing an independent national deterrent-halted a preliminary treaty for Franco-German nuclear cooperation. Germany had little choice but to acquiesce to deterrence as formulated by the United States. In the interview he conducted for War and Peace in the Nuclear Age: 'The Education of Robert McNamara,' Schmuckle elaborates on these and other topics. In building up the Bundeswehr, Strauss pushed to have some voice in North Atlantic Treaty Organization (NATO) decision-making, worked to overcome European mistrust of a rearmed Germany, and fought to regain its stature in Europe. Unsure whether exclusive reliance on a U.S. nuclear deterrent would be sustainable in the long term, Schmuckle recaps Germany's efforts to build a pan-European defense force-a proposal that failed to gain traction. He also supported NATO general Lauris Norstad's proposal that NATO become a fourth nuclear power. However, Britain's 1957 white paper Defense: Outline of Future Policy announced the island's intent to build an independent nuclear deterrent and reduce troop levels in Germany, which quashed the notion of NATO as a major nuclear power. The following year, de Gaulle proclaimed developing an independent nuclear force his government's highest priority. As a result, Schmuckle explains, Germans haven't significantly influenced the stationing of nuclear warheads and NATO decision-making. He recalls opposing U.S. secretary of defense Robert McNamara's theories of escalating warfare and preemptive strikes, and he protested against a dramatic increase in conventional forces, which he regarded as totally unrealistic. In the age of nuclear weapons, Schmuckle asserts, 'war does not make any sense any longer in Europe.'

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.

As staff secretary to President Dwight Eisenhower from 1954 to 1961, General Andrew Goodpaster was the person most privy to Eisenhower's thinking and key decisions during his White House years. Goodpaster began his long affiliation with Eisenhower as a staff officer under his leadership of the Supreme Headquarters Allied Powers Europe (SHAPE), and he went on to become the president's right-hand man on security matters. In this video segment, Goodpaster describes the inter-service rivalries that led Eisenhower to reorganize and centralize the armed forces, reflecting his general belief in systematic, integrated planning. Goodpaster's interview conducted for War and Peace in the Nuclear Age: 'A Bigger Bang for the Buck,' provides an intimate portrait of Eisenhower's leadership style and approach to policymaking. He describes how the president handled immense pressure to intervene in South and Southeast Asia as well as demands for a crash military buildup in the wake of bomber-gap and missile-gap reports. Goodpaster recalls that Eisenhower always saw Europe as vital to U.S. interests and repeatedly advocated strengthening the European alliance. The administration ushered in what came to be known as the "New Look" to sustain containment over the long term at a tolerable cost. Goodpaster describes a president confident in his military judgment despite the criticism that his administration endured. The introduction of 'massive retaliation' became the most controversial policy of the Eisenhower administration, and the downing of a U-2 spy plane dealt the gravest injury to his presidency. Goodpaster returns several times to the impact that the introduction of thermonuclear weapons had on Eisenhower's thinking, fueling the president's strong interest in 'Atoms for Peace,' limited arms control, and negotiation.

In this lesson, students go on a gallery walk about space exploration and then participate in a fishbowl discussion to make connections between this historical event and their lives today.

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.
