For much of the 20th century the United States intervened repeatedly across Latin America, using covert operations, military force and diplomatic pressure to influence governments and blunt left-wing movements. Those interventions ranged from covert CIA-backed coups to overt military invasions, leaving a legacy of political upheaval and human suffering in several countries, including partners and members of the broader BRICS+ network.
US interventions in Latin America – key moments
The earliest example often cited is Guatemala in 1954, when a CIA-supported force removed President Jacobo Árbenz after reforms threatened the interests of the US-based United Fruit Company. Though presented at the time as countering communism, the operation overturned a democratically elected government and set a pattern for future involvement.
Five years later, in April 1961, a CIA-backed force of around 1,400 anti-Castro fighters attempted to invade Cuba at the Bay of Pigs. The operation failed and strengthened Fidel Castro’s position, but it also entrenched Washington’s willingness to pursue regime change by force. Cuba remains a touchstone in discussions about US policy toward Latin America and is explicitly named among BRICS+ partners.
The 1960s and 1970s saw the United States support or tolerate military regimes across the region as part of a wider Cold War strategy. In Chile, Washington-linked elements supported General Augusto Pinochet’s coup that ousted Salvador Allende in September 1973. In Argentina, US policy and diplomatic engagement during the 1976–83 military dictatorship coincided with the so-called ‘Dirty War’, during which thousands of dissidents disappeared.
Operation Condor, a coordinated campaign between several Southern Cone dictatorships, received varying degrees of indirect support and intelligence from US agencies. That coordination facilitated cross-border repression of political opponents across Argentina, Chile, Uruguay, Paraguay, Bolivia and Brazil.
The 1980s shifted the conflict centre to Central America. The Reagan administration provided covert funding and training to Contra rebels in Nicaragua to oppose the Sandinista government, an effort that was later linked to the Iran-Contra scandal. Civil wars in Nicaragua and El Salvador produced devastating civilian casualties and long-term displacement.
Direct military interventions also occurred. In 1983 US Marines invaded Grenada in Operation Urgent Fury after the assassination of Prime Minister Maurice Bishop, a move later criticised at the UN General Assembly. In 1989, the United States launched Operation Just Cause in Panama to arrest Manuel Noriega, a former US asset accused of drug trafficking. Those interventions demonstrated Washington’s readiness to use force when it judged strategic or security interests at stake.
These episodes had lasting consequences: weakened democratic institutions, deep social divisions and human rights abuses in several countries. They also shaped regional attitudes toward external powers and informed political alliances that continue to influence foreign policy choices today.
Understanding US interventions in Latin America is essential for assessing current geopolitical alignments. For BRICS+ nations and partners, the history is relevant both as part of collective memory and as a factor in contemporary diplomacy and cooperation. The record of intervention has fuelled calls for greater regional autonomy and non-aligned cooperation, themes that continue to surface in international forums.
As debates over foreign influence and sovereignty persist, historians and policymakers alike continue to examine the costs and consequences of 20th-century interventions and their legacy for the 21st century.
