In 1972, professional advertisers contributed to a Vietnam antiwar campaign known as Unsell the War. In one of the public service television ads, actor Henry Fonda recites a litany of problems created by the war before looking into the camera and asking the pensive viewer, “What can you do about it? Well, this is still a democracy, isn’t it?”Footnote ¹

Americans continue to grapple with that fundamental question. In the wake of the 2020 presidential election, an attempted insurrection raised the specter of the national crisis surrounding the Civil War and its debates over nullification, secession, disenfranchisement, and the Lost Cause. The resilience of American democracy faces perhaps its sternest test since that time. In the fifty years since the Vietnam War staggered to its chastening conclusion, the United States has enjoyed only occasional moments of unity and optimism. Democracy appears more tenuous, common bonds less tangible, harmony an antiquated concept.

American citizens during the Vietnam War faced challenges to the functioning of their democracy as well. Every major American war encountered some degree of criticism, and a few generated contentious debates at the highest levels of government. American opposition to the Vietnam War, however, made it – outside of the Civil War – the most divisive military conflict in US history. Antiwar activism was early, broad, and persistent. It ranged from pacifist religious groups to liberal cold warriors to leftist radicals and spanned both deeply entrenched political insiders and fringe anarchists. Activists articulated moral, political, and economic arguments for ending the war. Tactically, participants joined electoral political campaigns, marched in peaceful and legal demonstrations, undertook educational activities, conducted solemn observances, committed civil disobedience, and on rare occasions engaged in acts of political violence. At its heart, however, the struggle to end the Vietnam War upheld the nation’s democratic principles against forces of political repression.

The war’s opponents worked through a fluctuating alliance consisting of diverse constituencies, separated by varied objectives and motivations but drawn together to pursue a shared goal. The core of the movement consisted primarily of highly educated, middle-class political liberals and moderate pacifists, many of whom had been previously active in the antinuclear and civil rights movements. Motivated by the belief that an American war in Indochina was a major foreign policy error, or represented an immoral application of US military power, this reformist center believed ending the war would largely restore the nation to its proper diplomatic role. Additional layers attached themselves to this core, hoping to withdraw from Vietnam not just as an end in itself, but to achieve other objectives. Civil rights groups believed the war diverted resources from programs addressing the political, social, and economic needs of African Americans. Chicanos created their own movement for similar reasons. Radicals and Black Power advocates attracted to a third-world perspective identified as allies of the North Vietnamese in combating American imperialism.Footnote ² The Old Left hoped antiwar sentiment would translate into calls for a radical social transformation. Pragmatic business leaders focused on the war’s negative impact on the economy. What these groups had in common was a belief, however tentative that may have been, that their actions could move the government to extricate the United States from the war in Indochina.

The Vietnam antiwar movement proceeded along mutually supportive paths: one within the formal political system and one outside. Dissent within the government existed from the beginning but expanded over time. Throughout the movement’s existence, distinct elements exerted greater influence at different points, although most remained engaged to varying degrees for the war’s duration. The liberal reformist core dominated until 1967 and after mid-1971, and intermittently during election campaigns and the fall 1969 Moratorium. Leftists were most evident during major coalition events of 1967 through the May Day demonstrations of spring 1971. Massive student protests in both 1968 and 1970 were ideologically ambiguous. Drawing encouragement and political leverage from the “outsider” movement, federal and state legislators and officials in the executive branch played their most significant role in collaboration with the activist core after 1971.

The Vietnam War years highlighted contending versions of what constituted patriotism. Most opponents of the war acted out of a sense of devotion to country. They challenged American policy in Vietnam as a means of holding the nation to its highest ideals; among them justice, democracy, independence and self-determination, the rule of law, equality of opportunity, morality, and humanitarianism. They did so as an exercise of their constitutional “right of the people peaceably to assemble, and to petition the government for a redress of grievances.”Footnote ³ This dissenting patriotism sometimes clashed with a more conventional patriotism that rejected any significant disagreement with the government and required unwavering support for American practices even when they clashed with its principles.

Significant dissent took place through the established political system. Antiwar activism generally aimed either directly or indirectly toward influencing the traditional levers of political power. Since American presidents committed the nation to war in Vietnam, activists from the beginning applied pressure to the executive branch to bring about changes in US policy that would end the war. When presidential resistance to public pressure persisted, activists increasingly lobbied federal legislators, pushing Congress to assert its constitutional authority to declare war and finance the government by extricating the nation from Southeast Asia. When Congress hesitated, activists gave greater emphasis to electoral politics, hoping to replace officeholders who maintained the status quo with individuals who disapproved of the war. Campaigns at the presidential, congressional, and even state and local levels played a major role in antiwar activism, even if government officials often appeared unresponsive to dissent.

Antiwar forces worked predominantly within conventional political boundaries. The overwhelming majority of protests were legal and peaceful. Their appeals ultimately addressed democratically elected officials who held the decision-making responsibility that could either end or prolong the war. Dissidents attempted to educate and influence both government leaders and the public. Presidents publicly ignored them, administration officials sometimes patronized them, members of Congress frequently denounced them, the populace largely rejected them. Upon encountering a political establishment that seemed resistant to public pressure, antiwar activists grew increasingly frustrated with a nonresponsive system. The growing size of mass demonstrations reflected widespread national anxiety over the war, but federal lawmakers appeared unmoved. This apparent indifference prompted a corresponding escalation of antiwar strategy.

Antiwar activity came at a price. Dissidents faced calculated government and nongovernment resistance. The presidential administrations of Lyndon Johnson and Richard Nixon coincided with most antiwar activism. Neither truly comprehended what motivated activists, nor did they make serious attempts to understand them. Each sought confirmation of their Cold War preconceptions that dissent must be inspired and sustained by international communism. United States intelligence analysis, however, consistently refuted that belief, finding an independently directed and supported domestic movement. This did not prevent political leaders from red-baiting and denigrating the movement, and both federal and local governments poured substantial resources into harassing, spying on, and infiltrating antiwar groups to disrupt their activities and undermine their message.

Years of effort produced little visible impact and activists faced fatigue, inertia, and anguish. Some abandoned their apparently futile tactics for more provocative and confrontational efforts, which generated further internal divisions and met with even greater public disapproval. For everyone who dropped away from activism, however, others joined, and the movement showed admirable perseverance and tenacity. Eventually their efforts produced results. Despite public disclaimers, Johnson and Nixon both felt unsettled by the movement and made political decisions based in part on antiwar pressures. Government leaders, ranging from Congress and executive branch members at the federal level to state and municipal officials, sometimes opposed US policies regarding Vietnam. As public opinion turned against the war and congressional opposition flourished, the antiwar movement shed much of its radicalism and moved more easily through the traditional political structure.

As American dissidents prior to the Vietnam War found, operating solely within the electoral system often proved insufficient. Voting alone was too infrequent to adequately address concerns of the magnitude of an undeclared war. It also proved overly restrictive, since many demonstrators were legally too young to vote at a time when suffrage began at age twenty-one. Working in the hard-fought tradition of abolitionists, suffragists, utopians, and twentieth-century labor and civil rights activists, antiwar demonstrators by necessity adopted legitimate political measures outside the electoral process to achieve their goals.

Activists pursued direct action through both legal and illegal means. Withholding the manpower necessary to wage war played a significant role in opposing the war. Resistance to the military draft was widespread. Those not subject to the Selective Service System supported individual conscientious objectors and, on rare occasions, destroyed draft records to impede the government’s ability to induct men into the armed forces. Activists also applied economic pressure through moral suasion, corporate resolutions, and economic boycotts against American corporations that contributed to the war effort.

One of the common misperceptions regarding the Vietnam antiwar movement is that it was dominated by political and cultural radicals. Typically, antiwar activism took place at the local level through relatively small actions usually conducted by one or a handful of cooperating organizations or unaffiliated citizens. The antiwar constituencies are apparent in many of the names of their organizations: students, clergy, business executives, women, mothers, writers and artists, Quakers, scientists, Catholics, lawyers, trade unionists, veterans, and physicians, among others. The movement was much broader than coalition-sponsored events, which typified only one form of activism. Mass public demonstrations, however, represented the most visible and heavily covered expressions of antiwar dissent. Many of those large national events operated under umbrella coalitions that were incredibly diverse and surprisingly contentious. Part of the reason the public misunderstood the antiwar movement, then and now, came from movement leaders themselves. A relatively small core of coalition leaders deliberately discouraged more moderate elements from participating by claiming a more authentic or more lengthy commitment to ending the war. Those moderate elements – committed to the existing political system and to using legal and nonviolent tactics – however, were equally legitimate expressions of national opposition to the war. Some coalition leaders tried to direct antiwar constituencies where they did not wish to go, and the movement at large told the nation things it did not wish to hear. Most grassroots activists remained largely unaware or unconcerned with the internal sectarian disputes conducted at the highest levels of coalition planning and typically represented broadly mainstream political opinions. A handful of small Marxist organizations and more numerous New Left and countercultural rebels certainly helped mobilize or later attach themselves to the antiwar cause. Each in their own way contributed something of value, although the identification of those groups as antiwar activists cost the larger movement significantly in the court of public opinion. As a result, the focus on national coalition-organized demonstrations by contemporary media accounts and subsequent scholarly analyses has left an exaggerated perception of radical dominance of the antiwar movement in both its ideology and tactics.

Contrary to a second misperception, antiwar constituencies and military veterans did not share an instinctive and pervasive mutual antipathy. Tensions between civilian and military personnel certainly existed, and they naturally approached these issues from different perspectives, but they cooperated more broadly than is generally understood. Both active-duty soldiers and discharged veterans participated in antiwar actions during the Vietnam War, either as part of coalition activities or in separate events. The civilian movement also frequently supported active-duty soldiers through financial, legal, and physical assistance.

The culture wars that plague the national debate into the 2020s were not caused by the Vietnam War or its opposition, but they were certainly exposed and intensified by the political alignments that coalesced over that conflict. The counterculture – a largely but not exclusively generational movement – challenged accepted social and cultural norms. Various elements practiced sexual liberation, flexible gender roles, alternative spirituality, and experimentation with mind-altering drugs. They pursued unique directions in fashion, behavior, and artistic expression. Many questioned and contested American social inequality, consumerism and materialism, and an aggressive foreign policy. The wounds from these national battles never fully healed and left scars on the body politic. The disruption of American foreign policy following the Vietnam War led to a temporary restraint in foreign entanglements, sometimes called the Vietnam Syndrome. The shadow of that conflict remains. The rapid collapse of the American-backed government in Afghanistan in 2021 – propped up by four US presidential administrations – revived the memories of Vietnam once again. Furthermore, the sabotage of fundamental American institutions implemented during the administrations of Donald Trump meant that the saboteurs were often not only assaulting the walls of government from the outside; they were within the government.

Antiwar protest contained a substantial international component. Demonstrations occurred in world cities among both American expatriates and foreign nationals. International leaders occasionally provided unsolicited and mostly unwelcome advice about how America might extricate itself from Indochina. Governments allied with the United States generally resisted efforts to pull them into what they perceived to be an unwise commitment. American soldiers and South Vietnamese citizens sometimes made their case within Vietnam itself.

The Vietnam antiwar movement emerged as early as 1963 as activists tried to end what they believed to be a misguided commitment to a series of corrupt and unrepresentative regimes in Saigon. From there it evolved into attempts to prevent the United States from committing its own combat forces and, when that failed, activists tried to slow and reverse American military escalation. After Richard Nixon announced his Vietnamization strategy of gradually shifting offensive ground operations from US to South Vietnamese forces, they insisted on the most rapid possible US withdrawal and for terminating by a specific date the expanded air war rather than leaving the conclusion open-ended. The mass movement peaked in late 1969, but it remained capable of overwhelming response whenever President Nixon made significant missteps. From that point the umbrella coalitions were less significant than smaller, more focused campaigns. At different times the movement emphasized the loss of individual rights through the military draft, campus collaboration through ROTC and defense research, economic costs to Americans, and corporate complicity. It shifted from small organizational efforts to mass umbrella demonstrations and back to single organization or smaller, more focused coalition activities.

For more than a decade, American citizens fought to end the war in Vietnam. At its conclusion, many promoted amnesty for people who resisted the military draft and deserted the wartime armed forces. Still others expanded their concerns into the injustices and inequities of contemporary American society. That such diverse constituencies – united across ideological, class, and generational boundaries – persisted for so long against such great odds is a testament to their competence and dedication in service to their country. Ultimately, however, antiwar activists were neither victorious nor defeated. Public opinion generally ended up supporting many of the positions advocated by the movement, while a majority of people distanced themselves from those who carried the message. The movement failed to prevent the war’s escalation and an extended US military commitment, but it applied significant pressure that proved capable of influencing presidential political options and decisions and creating a social environment of war weariness that made ending a misguided and unsuccessful conflict an acceptable national option.
