The development of military arms harnessing nuclear energy for mass destruction has inspired continual efforts to control them. Since 1945, the United States, the Soviet Union, the United Kingdom, France, the People’s Republic of China (PRC), Israel, India, Pakistan, North Korea, and South Africa acquired control over these powerful weapons, though Pretoria dismantled its small cache in 1989 and Russia inherited the Soviet arsenal in 1996. Throughout this period, Washington sought to limit its nuclear forces in tandem with those of Moscow, prevent new states from fielding them, discourage their military use, and even permit their eventual abolition.
Scholars disagree about what explains the United States’ distinct approach to nuclear arms control. The history of U.S. nuclear policy treats intellectual theories and cultural attitudes alongside technical advances and strategic implications. The central debate is one of structure versus agency: whether the weapons’ sheer power, or historical actors’ attitudes toward that power, drove nuclear arms control. Among those who emphasize political responsibility, there are two further disagreements: (1) the relative influence of domestic protest, culture, and politics; and (2) whether U.S. nuclear arms control aimed first at securing the peace by regulating global nuclear forces or at bolstering American influence in the world.
The intensity of nuclear arms control efforts tended to rise or fall with the likelihood of nuclear war. Harry Truman’s faith in the country’s monopoly on nuclear weapons caused him to sabotage early initiatives, while Dwight Eisenhower’s belief in nuclear deterrence led in a similar direction. Fears of a U.S.-Soviet thermonuclear exchange mounted in the late 1950s, stoked by atmospheric nuclear testing and widespread radioactive fallout, which stirred protest movements and diplomatic initiatives. The spread of nuclear weapons to new states motivated U.S. presidents (John Kennedy in the vanguard) to mount a concerted campaign against “proliferation,” climaxing with the 1968 Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Richard Nixon was exceptional. His reasons for signing the Strategic Arms Limitation Treaty (SALT I) and Anti-Ballistic Missile Treaty (ABM) with Moscow in 1972 were strategic: to buttress the country’s geopolitical position as U.S. armed forces withdrew from Southeast Asia. The rise of protest movements and Soviet economic difficulties after Ronald Reagan entered the Oval Office brought about two more landmark U.S.-Soviet accords—the 1987 Intermediate Ballistic Missile Treaty (INF) and the 1991 Strategic Arms Reduction Treaty (START)—the first occasions on which the superpowers eliminated nuclear weapons through treaty. The country’s attention swung to proliferation after the Soviet collapse in December 1991, as failed states, regional disputes, and non-state actors grew more prominent. Although controversies over Iraq, North Korea, and Iran’s nuclear programs have since erupted, Washington and Moscow continued to reduce their arsenals and refine their nuclear doctrines even as President Barack Obama proclaimed his support for a nuclear-free world.

The origins of the Vietnam War can be traced to France’s colonization of Indochina in the late 1880s. The Viet Minh, led by Ho Chi Minh, emerged as the dominant anti-colonial movement by the end of World War II, though Viet Minh leaders encountered difficulties as they tried to consolidate their power on the eve of the First Indochina War against France. While that war was, initially, a war of decolonization, it became a central battleground of the Cold War by 1950. The lines of future conflict were drawn that year when the Peoples Republic of China and the Soviet Union recognized and provided aid to the Democratic Republic of Vietnam in Hanoi, followed almost immediately by Washington’s recognition of the State of Vietnam in Saigon. From that point on, American involvement in Vietnam was most often explained in terms of the Domino Theory, articulated by President Dwight D. Eisenhower on the eve of the Geneva Conference of 1954. The Franco-Viet Minh ceasefire reached at Geneva divided Vietnam in two at the 17th parallel, with countrywide reunification elections slated for the summer of 1956. However, the United States and its client, Ngo Dinh Diem, refused to participate in talks preparatory to those elections, preferring instead to build South Vietnam as a non-communist bastion. While the Vietnamese communist party, known as the Vietnam Worker’s Party in Hanoi, initially hoped to reunify the country by peaceful means, it reached the conclusion by 1959 that violent revolution would be necessary to bring down the “American imperialists and their lackeys.” In 1960, the party formed the National Liberation Front for Vietnam and, following Diem’s assassination in 1963, passed a resolution to wage all-out war in the south in an effort to claim victory before the United States committed combat troops. After President John F. Kennedy took office in 1961, he responded to deteriorating conditions in South Vietnam by militarizing the American commitment, though he stopped short of introducing dedicated ground troops. After Diem and Kennedy were assassinated in quick succession in November 1963, Lyndon Baines Johnson took office determined to avoid defeat in Vietnam, but hoping to prevent the issue from interfering with his domestic political agenda. As the situation in South Vietnam became more dire, LBJ found himself unable to maintain the middle-of-the-road approach that Kennedy had pursued. Forced to choose between escalation and withdrawal, he chose the former in March 1965 by launching a sustained campaign of aerial bombardment, coupled with the introduction of the first officially designated U.S. combat forces to Vietnam.
Peace activism in the United States between 1945 and the 2010s focused mostly on opposition to U.S. foreign policy, efforts to strengthen and foster international cooperation, and support for nuclear nonproliferation and arms control. The onset of the Cold War between the United States and the Soviet Union marginalized a reviving postwar American peace movement emerging from concerns about atomic and nuclear power and worldwide nationalist politics that everywhere seemed to foster conflict, not peace. Still, peace activism continued to evolve in dynamic ways and to influence domestic politics and international relations.
Most significantly, peace activists pioneered the use of Gandhian nonviolence in the United States and provided critical assistance to the African American civil rights movement, led the postwar antinuclear campaign, played a major role in the movement against the war in Vietnam, helped to move the liberal establishment (briefly) toward a more dovish foreign policy in the early 1970s, and helped to shape the political culture of American radicalism. Despite these achievements, the peace movement never regained the political legitimacy and prestige it held in the years before World War II, and it struggled with internal divisions about ideology, priorities, and tactics.
Peace activist histories in the 20th century tended to emphasize organizational or biographical approaches that sometimes carried hagiographic overtones. More recently, historians have applied the methods of cultural history, examining the role of religion, gender, and race in structuring peace activism. The transnational and global turn in the historical discipline has also begun to make inroads in peace scholarship. These are promising new directions because they situate peace activism within larger historical and cultural developments and relate peace history to broader historiographical debates and trends.
In the years after the Civil War, Polish immigrants became an important part of the American working class. They actively participated in the labor movement and played key roles in various industrial strikes ranging from the 1877 Railroad Strike through the rise of the CIO and the post-1945 era of prosperity. Over time, the Polish American working class became acculturated and left its largely immigrant past behind while maintaining itself as an ethnic community. It also witnessed a good deal of upward mobility, especially over several generations. This ethnic community, however, continued to be refreshed with immigrants throughout the 20th century.
As with the larger American working class, Polish American workers were hard hit by changes in the industrial structure of the United States. Deindustrialization turned the centers of much of the Polish American community into the Rust Belt. This, despite a radical history, caused many to react by turning toward conservative causes in the late 20th and early 21st centuries.

From the revolutionary era to the post-9/11 years, public and private actors have attempted to shape U.S. foreign relations by persuading mass audiences to embrace particular policies, people, and ways of life. Although the U.S. government conducted wartime propaganda activities prior to the 20th century, it had no official propaganda agency until the Committee on Public Information (CPI) was formed in 1917. For the next two years, CPI aimed to generate popular support for the United States and its allies in World War I. In 1938, as part of its Good Neighbor Policy, the Franklin Roosevelt administration launched official informational and cultural exchanges with Latin America. Following American entry into World War II, the U.S. government created a new propaganda agency, the Office of War Information (OWI). Like CPI, OWI was disbanded once hostilities ended. But in the fall of 1945, to combat the threats of anti-Americanism and communism, President Harry S. Truman broke with precedent and ordered the continuation of U.S. propaganda activities in peacetime. After several reorganizations within the Department of State, all U.S. cultural and information activities came under the purview of the newly created U.S. Information Agency (USIA) in 1953. Following the dissolution of USIA in 1999, the State Department reassumed authority over America’s international information and cultural programs through its Office of International Information Programs.
Public authorities are agencies created by governments to engage directly in the economy for public purposes. They differ from standard agencies in that they operate outside the administrative framework of democratically accountable government. Since they generate their own operating income by charging users for goods and services and borrow for capital expenses based on projections of future revenues, they can avoid the input from voters and the regulations that control public agencies funded by tax revenues.
Institutions built on the public authority model exist at all levels of government and in every state. A few of these enterprises, such as the Tennessee Valley Authority and the Port Authority of New York and New Jersey, are well known. Thousands more toil in relative obscurity, operating toll roads and bridges, airports, transit systems, cargo ports, entertainment venues, sewer and water systems, and even parking garages. Despite their ubiquity, these agencies are not well understood. Many release little information about their internal operations. It is not even possible to say conclusively how many exist, since experts disagree about how to define them, and states do not systematically track them.
One thing we do know about public authorities is that, over the course of the 20th century, these institutions have become a major component of American governance. Immediately following the Second World War, they played a minor role in public finance. But by the early 21st century, borrowing by authorities constituted well over half of all public borrowing at the sub-federal level. This change means that increasingly the leaders of these entities, rather than elected officials, make key decisions about where and how to build public infrastructure and steer economic development in the United States

A concerted movement to promote sex education in America emerged in the early 20th century as part of a larger public health movement that also responded to the previous century’s concerns about venereal disease, prostitution, “seduction,” and “white slavery.” Sex education, therefore, offered a way to protect people (especially privileged women) from sexual activity of all kinds—consensual and coerced. A widespread introduction into public schools did not occur until after World War I. Sex education programs in schools tended to focus on training for heterosexual marriage at a time when high school attendance spiked in urban and suburban areas. Teachers often segregated male and female students.
Beyond teaching boys about male anatomy and girls about female anatomy, reformers and educators often conveyed different messages and used different materials, depending on the race of their students. Erratic desegregation efforts during the Civil Rights movement renewed a crisis in sex education programs. Parents and administrators considered sexuality education even more dangerous in the context of a racially integrated classroom. The backlash against sex education in the schools kept pace with the backlash against integration, with each often used to bolster the other. Opponents of integration and sex education, for example, often used racial language to scare parents about what kids were learning, and with whom.
In the 1980s and 1990s, the political power of the evangelical movement in the United States attracted support for “abstinence-only” curricula that relied on scare tactics and traditional assumptions about gender and sexuality. The ever-expanding acceptance (both legal and social) of lesbian, gay, bisexual, or transgender identity directly challenged the conservative turn of abstinence-until-marriage sex education programs. The politics of gender, race, class, and sexual orientation have consistently shaped and limited sex education.
Radicalism in the United States since 1945 has been varied, complex, and often fragmented, making it difficult to analyze as a coherent movement. Communist and pro-Soviet organizations remained active after World War II, but a proliferation of noncommunist groups in the 1940s and 1950s, formed by those disillusioned by Marxist theory or the Soviet Union, began to chart a new course for the American Left. Eschewing much of the previous focus on labor, the proletariat, and Marxist doctrine, American postwar radical organizations realigned around humanist values, moral action, democracy, and even religion, with tenuous connections to Marxism, if any. The parameters of postwar radical moral theory were not always clearly defined, and questions of strategy and vision caused frequent divisions among activists. Nonetheless, claims of individual dignity and freedom continued to frame left radicalism into the late 20th century, emphasizing identity politics, community-building initiatives, and cultural expression in the streets of U.S. cities and the halls of academia. The presidential campaign of Bernie Sanders in 2016 helped revitalize leftist rhetoric on the national stage with its calls for racial and economic equality on moral terms.
Rap is the musical practice of hip hop culture that features vocalists, or MCs, reciting lyrics over an instrumental beat that emerged out of the political and economic transformations of New York City after the 1960s. Black and Latinx youth, many of them Caribbean immigrants, created this new cultural form in response to racism, poverty, urban renewal, deindustrialization, and inner-city violence. These new cultural forms eventually spread beyond New York to all regions of the United States as artists from Los Angeles, New Orleans, Miami, and Chicago began releasing rap music with their own distinct sounds. Despite efforts to demonize and censor rap music and hip hop culture, rap music has served as a pathway for social mobility for many black and Latinx youth. Many artists have enjoyed crossover success in acting, advertising, and business. Rap music has also sparked new conversations about various issues such as electoral politics, gender and sexuality, crime, policing, and mass incarceration, as well as technology.
Jimmy Carter’s “Crisis of Confidence Speech” of July 1979 was a critical juncture in post-1945 U.S. politics, but it also marks an exemplary pivot in post-1945 religion. Five dimensions of faith shaped the president’s sermon. The first concerned the shattered consensus of American religion. When Carter encouraged Americans to recapture a spirit of unity, he spoke in a heartfelt but spent language more suitable to Dwight Eisenhower’s presidency than his own. By 1979, the Protestant-Catholic-Jewish consensus of Eisenhower’s time was fractured into a dynamic pluralism, remaking American religion in profound ways. Carter’s speech revealed a second revolution of post-1945 religion when it decried its polarization and politicization. Carter sought to heal ruptures that were dividing the nation between what observers, two decades hence, would label “red” (conservative Republican) and “blue” (liberal Democratic) constituencies. Yet his endeavors failed, as would be evidenced in the religious politics of Ronald Reagan’s era, which followed. Carter championed community values as the answer to his society’s problems aware of yet a third dawning reality: globalization. The virtues of localism that Carter espoused were in fact implicated in (and complicated by) transnational forces of change that saw immigration, missionary enterprises, and state and non-state actors internationalizing the American religious experience. A fourth illuminating dimension of Carter’s speech was its critique of America’s gospel of wealth. Although this “born-again” southerner was a product of the evangelical South’s revitalized free-market capitalism, he lamented how laissez-faire Christianity had become America’s lingua franca. Finally, Carter wrestled with secularization, revealing a fifth feature of post-1945 America. Even though faith commitments were increasingly cordoned off from formal state functions during this time, the nation’s political discourse acquired a pronounced religiosity. Carter contributed by framing mundane issues (such as energy) in moral contexts that drew no hard-and-fast boundaries between matters of the soul and governance. Drawn from the political and economic crises of his moment, Carter’s speech thus also reveals the all-enveloping tide of religion in America’s post-1945 age.
