27.2.6 Nixon, Foreign Policy, and the Limits of Power

Richard Nixon’s foreign policy redefined Cold War dynamics, but his aggressive strategies and covert actions highlighted the limits of American power and deepened public distrust.

Strategy in Vietnam

Vietnamization

A cornerstone of Nixon’s Vietnam policy was Vietnamization, a plan to gradually withdraw American troops while increasing the combat role of the South Vietnamese army (ARVN). Announced in 1969, this strategy aimed to maintain US commitments without the political cost of American casualties. The expectation was that the ARVN would be sufficiently trained and equipped to counter the North Vietnamese Army (NVA) independently.

However, the ARVN’s effectiveness varied, and critics argued that Vietnamization was more about domestic political expediency than genuine stability in Vietnam.

Secret Bombings and Expansion into Cambodia

While publicly advocating for de-escalation, Nixon authorised covert operations to disrupt enemy supply lines:

  • Operation Menu (1969–70): This involved the secret bombing of suspected Viet Cong and NVA sanctuaries in Cambodia, a neutral country. The aim was to destroy the Ho Chi Minh Trail and safe havens that the enemy used to launch attacks into South Vietnam.

  • In April 1970, Nixon escalated further by ordering a ground invasion of Cambodia. This controversial action bypassed Congress and ignited widespread protests in the US, most infamously resulting in the Kent State shootings, where National Guardsmen killed four students during an anti-war demonstration.

These actions demonstrated Nixon’s willingness to expand the war geographically despite promises to reduce US involvement.

Peace Negotiations and the Paris Peace Accords (1973)

Nixon and his National Security Advisor, Henry Kissinger, pursued negotiations with North Vietnam alongside military pressure. This two-pronged strategy sought to achieve ‘peace with honour’ — ending US involvement without appearing to abandon South Vietnam.

Key developments included:

  • Secret talks between Kissinger and North Vietnamese diplomat Le Duc Tho began in 1969, with public negotiations running parallel.

  • Despite bombing campaigns like the ‘Christmas Bombings’ of 1972, which aimed to force North Vietnamese concessions, both sides remained intransigent on critical issues such as the political future of South Vietnam.

  • The Paris Peace Accords were signed in January 1973. Main terms included a ceasefire, withdrawal of US troops, the return of prisoners of war, and the promise of free elections in South Vietnam.

While the accords officially ended direct US military involvement, they failed to secure lasting peace. Fighting soon resumed between North and South Vietnamese forces, exposing the fragility of Nixon’s settlement.

Role of Henry Kissinger and Détente

Détente with the USSR: SALT I

Nixon and Kissinger shifted US Cold War policy from confrontation to détente, aiming to ease tensions with the Soviet Union through negotiation and arms control:

  • In 1972, Nixon became the first sitting US president to visit Moscow. He and Soviet leader Leonid Brezhnev signed the Strategic Arms Limitation Treaty (SALT I), which:

    • Froze the number of intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs).

    • Established the Anti-Ballistic Missile (ABM) Treaty, limiting missile defence systems.

This milestone reflected a pragmatic approach: by stabilising the nuclear balance, both superpowers reduced the risk of direct conflict and shifted the Cold War towards managed rivalry.

Opening Relations with China

Perhaps Nixon’s most surprising diplomatic move was re-establishing relations with the People’s Republic of China (PRC):

  • In February 1972, Nixon visited Beijing, meeting Chairman Mao Zedong and Premier Zhou Enlai. This thaw ended 20 years of hostility and non-recognition.

  • The visit had strategic aims:

    • Exploit the Sino-Soviet split to gain leverage over the USSR.

    • Open economic and diplomatic opportunities in Asia.

    • Pressure North Vietnam by isolating it diplomatically.

Nixon’s China initiative was hailed as a diplomatic masterstroke, altering global alignments and demonstrating the administration’s realpolitik approach.

Policy in Latin America and CIA Interventions

While pursuing détente with major powers, Nixon’s foreign policy in Latin America reflected Cold War fears of communist expansion:

  • In Chile, the Nixon administration viewed the democratically elected socialist president, Salvador Allende, as a threat. The CIA provided covert support to opposition groups and encouraged a climate for a military coup.

  • In 1973, the Chilean military, led by General Augusto Pinochet, overthrew Allende, who died during the coup. Pinochet’s regime was marked by severe human rights abuses but received tacit US backing as a bulwark against communism.

Nixon and Kissinger’s willingness to undermine elected governments in Latin America epitomised the moral ambiguities of Cold War containment and fuelled global criticism of American interventionism.

Public Distrust and Divisions over Foreign Intervention

Nixon’s aggressive and often secretive foreign policies deepened a crisis of trust between the American government and its citizens:

  • The Pentagon Papers, leaked in 1971 by Daniel Ellsberg, revealed a pattern of government deception about the Vietnam War’s progress across multiple administrations. Although the papers predated Nixon, they compounded scepticism about official statements.

  • Revelations of the Cambodian bombings, once publicised, reinforced perceptions that Nixon was expanding the war covertly, contrary to his promises of de-escalation.

  • Domestic protests, already intense under Johnson, surged under Nixon’s tenure due to Cambodia and the Kent State tragedy. The anti-war movement broadened, and public support for interventionism waned.

  • This environment contributed to the broader ‘credibility gap’, a term describing the growing disconnect between government rhetoric and reality. The Watergate scandal, though primarily a domestic political crisis, further eroded confidence in Nixon’s leadership and compounded disillusionment with the American political system.

Limits of Power

Nixon’s foreign policy achievements, especially détente and the opening to China, marked significant shifts in Cold War diplomacy. However, they also exposed the limits of American power:

  • Despite massive expenditure and military might, the US failed to secure a definitive victory in Vietnam, highlighting the difficulties of fighting protracted conflicts against ideologically motivated, guerrilla-style opponents.

  • Covert interventions in Latin America and Southeast Asia undermined America’s image as a champion of democracy, feeding anti-American sentiment abroad and domestic cynicism at home.

  • The tension between public opinion and executive power became a persistent theme, restricting future presidents’ freedom to conduct foreign policy without congressional and public scrutiny.

Together, these factors illustrate how Nixon’s efforts to assert American strength often revealed the constraints imposed by international complexities and domestic backlash. His legacy in foreign affairs remains a study in both bold diplomacy and the enduring challenges of wielding global influence responsibly.

FAQ

Nixon justified the secret bombings and the 1970 Cambodian incursion as essential measures to protect American troops and force North Vietnam into meaningful negotiations. Publicly, he presented the incursion as a necessary, limited action to destroy enemy sanctuaries and supply lines used by the Viet Cong and North Vietnamese Army to launch attacks into South Vietnam. He argued that cutting off the Ho Chi Minh Trail in Cambodia would weaken the enemy’s capacity to sustain warfare and thereby accelerate ‘Vietnamization’. To Congress, Nixon initially downplayed the scope and secrecy of the operations, claiming executive authority as Commander-in-Chief during wartime. He insisted that swift, decisive action was vital to protect the lives of American soldiers and stabilise South Vietnam’s borders. Despite this, many legislators were angered by the lack of consultation, resulting in increased demands for congressional oversight of war powers. The controversy led directly to the War Powers Resolution of 1973, limiting presidential military action without congressional approval.

Nixon’s foreign policy, particularly his unilateral actions in Vietnam and secret operations in Cambodia, strained relations with some European NATO allies who felt sidelined and endangered by unpredictable American decisions. Many European leaders, especially in Britain, France, and West Germany, were critical of the US escalation and covert bombings, fearing it would destabilise Southeast Asia further and fuel anti-American sentiment globally. Nixon’s focus on bilateral superpower diplomacy with the USSR and China also worried Europeans; they feared Europe’s strategic importance was being downgraded in favour of direct US-Soviet détente and the opening to China. This shift challenged NATO’s cohesion, with some allies seeking a more independent foreign policy stance, exemplified by France’s continued pursuit of a distinct European voice in global affairs. Economically, Nixon’s abandonment of the Bretton Woods system in 1971, including the end of the dollar’s convertibility to gold, also caused friction, affecting transatlantic trade and monetary stability. Overall, his foreign policy created tensions that European allies had to carefully navigate.

Within the United States, Nixon’s policy of détente drew sharp criticism from both ends of the political spectrum. Conservative hawks argued that détente was too conciliatory towards the Soviet Union and risked legitimising communist regimes without adequately curbing their global ambitions. They believed that arms limitation treaties like SALT I placed disproportionate restrictions on US capabilities while allowing the USSR to modernise and expand its arsenal in other ways. Conversely, liberal critics and elements of the Democratic Party feared that détente prioritised relations with authoritarian regimes at the expense of human rights and democratic values. They accused Nixon and Kissinger of ignoring or downplaying Soviet repression and human rights abuses in the name of strategic stability. Some also argued that détente failed to reduce Cold War tensions meaningfully, as regional conflicts and proxy wars continued worldwide. Additionally, revelations about backchannel deals and secret diplomacy raised concerns about the transparency and accountability of foreign policy decision-making during this period.

Nixon’s approach to Latin America set a precedent for aggressive covert intervention that influenced subsequent US policies in the region during the 1970s and beyond. His administration’s support for the 1973 coup in Chile, which overthrew President Salvador Allende, signalled a willingness to use the CIA and economic pressure to undermine leftist governments perceived as threats to US interests. This encouraged a broader pattern in which successive administrations justified backing authoritarian anti-communist regimes across Latin America, often ignoring human rights abuses to maintain regional stability and contain Soviet influence. For example, the Nixon era laid groundwork for later operations in Argentina during its ‘Dirty War’, US support for right-wing regimes in Central America, and tacit endorsement of Operation Condor, a network of South American dictatorships coordinating to suppress dissent. Nixon’s actions reinforced the Cold War mindset that Latin America was a front in the ideological battle, legitimising covert action as an acceptable tool of foreign policy despite significant ethical and humanitarian costs.

Nixon’s 1972 visit to China fundamentally shifted the global balance of power by exploiting the deepening Sino-Soviet split and reshaping the triangular relationship among the US, USSR, and China. Before this diplomatic breakthrough, China had been diplomatically and economically isolated since the communist revolution in 1949. By recognising the strategic benefit of engaging Beijing, Nixon and Kissinger aimed to pressure the Soviet Union into more favourable arms control and diplomatic concessions through increased competition. The visit led to the Shanghai Communiqué, which set the framework for normalising relations and acknowledged the ‘One China’ policy regarding Taiwan. Internationally, Nixon’s opening to China weakened the united communist front, forced Moscow to reassess its foreign policy, and accelerated détente with the USSR. It also positioned the US as a key influencer in East Asia’s geopolitics. For China, the rapprochement provided access to Western technology, trade, and a counterweight against Soviet hostility. The visit remains a milestone in Cold War diplomacy for its lasting impact on superpower dynamics.

Practice Questions

To what extent did Nixon’s foreign policy succeed in achieving ‘peace with honour’ in Vietnam?

Nixon’s policy partly achieved ‘peace with honour’ by withdrawing US troops and securing the Paris Peace Accords in 1973. Vietnamization reduced American casualties, appeasing domestic opposition. However, secret bombings and the Cambodian incursion contradicted claims of de-escalation and intensified protests. The settlement did not guarantee South Vietnam’s security, as fighting resumed soon after. While Nixon avoided outright defeat during his presidency, the fall of Saigon in 1975 demonstrated the fragility of his strategy. Therefore, while politically expedient, Nixon’s approach ultimately failed to secure a stable, honourable peace in Vietnam.

How significant was the role of Henry Kissinger in shaping Nixon’s foreign policy?

Henry Kissinger played a crucial role in shaping Nixon’s foreign policy. As National Security Advisor, he orchestrated secret negotiations with North Vietnam, leading to the Paris Peace Accords. Kissinger was instrumental in pursuing détente, brokering SALT I with the USSR and arranging Nixon’s groundbreaking visit to China, exploiting the Sino-Soviet split. His realpolitik approach prioritised pragmatic alliances over ideological divides, reshaping Cold War dynamics. Additionally, he oversaw controversial covert operations in Latin America, such as supporting the Chilean coup. Overall, Kissinger’s influence was central to both the successes and moral ambiguities of Nixon’s foreign policy.
