American Crime Case #86: 1964 Brazil Coup and Rise of Brutal Military Dictatorship

Bob Avakian has written that one of three things that has “to happen in order for there to be real and lasting change for the better: People have to fully confront the actual history of this country and its role in the world up to today, and the terrible consequences of this.” (See “3 Things that have to happen in order for there to be real and lasting change for the better.”)

In that light, and in that spirit, “American Crime” is a regular feature of Each installment focuses on one of the 100 worst crimes committed by the U.S. rulers—out of countless bloody crimes they have carried out against people around the world, from the founding of the U.S. to the present day.

THE CRIME: In 1964, a section of the Brazilian military carried out a coup that overthrew Brazilian President João Goulart. The coup gave rise to two decades of a murderous and brutal military dictatorship and atrocities that led to the disappearance and death of close to 1,000 political opponents, and the systematic torture of over 30,000 more.

The coup had been anticipated—and worked for—by the U.S. for two years or more. And the U.S. provided supplies and funding for the coup. Just before the coup, the U.S. ambassador to Brazil received a secret telegram from Secretary of State Dean Rusk stating that the administration had decided to immediately mobilize a naval task force to take up position off the coast of Brazil including U.S. Navy tankers, along with an airlift of 110 tons of ammunition and other equipment including “CS agent”—a special gas used against street protests. President Lyndon Johnson was briefed on and signed off on that. Goulart was unable and unwilling to mobilize armed resistance, and within days of the coup he fled to neighboring Uruguay. The U.S. immediately recognized the new regime, and declared that the coup by the “democratic forces” had staved off the hand of international communism.

The years of military dictatorships that followed led to the killing of hundreds of political opponents, possibly as many as a thousand. This includes a battle in the Amazon jungle where scores of left-wing rebels were slaughtered. The army used napalm, firebombs, and torture, and carried out orders to execute every single guerrilla captured alive.

In 2007, Brazil’s commission investigating this period reported that 280 different types of torture were inflicted on “subversives” at 242 clandestine torture centers, by hundreds of individual torturers—aimed at crushing opposition groups and intimidating and silencing any other opponents. Tens of thousands were rounded up and imprisoned and/or tortured during the years of military rule.


U.S. presidents Kennedy and Johnson: A month and a half before Kennedy’s assassination in November 1963, Kennedy held a two-day meeting with his cabinet where the developing war in Vietnam and political developments in Brazil were discussed. Here Kennedy openly discussed the option of overthrowing Goulart’s government.


President Kennedy, in October 1963: “What kind of liaison do we have with the [Brazilian] military?”... “We’ve got to do something about Brazil.”

President Johnson, days before the coup: “I think we ought to take every step that we can, be prepared to do everything that we need to do.” (Instructing his aides about U.S. support for the coup as the Brazilian military moved against Goulart on March 31, 1964.)

Continuing under Johnson, the U.S. carried out a systematic campaign to destabilize Brazil, covertly organizing opposition and street protests against Goulart. Meanwhile, they closely watched unfolding developments towards a coup. Johnson made clear to his advisers that the U.S. should do everything it could to assist the impending coup to make sure it was successful.

As the coup was about to be launched, Johnson authorized “Operation Brother Sam.” The U.S. military supplied arms, ammunition and gasoline for the coup, and was prepared to send combat troops if the overthrow of Goulart met with strong resistance. And a massive naval force was dispatched.

Dean Rusk and Robert McNamara, secretaries of state and defense under President Johnson: These architects of the genocidal war against Vietnam were also overseeing the covert activities that set the stage for the coup, and monitoring and directing the massive backup that was sent to prevent, and if necessary crush, any opposition to the coup that might arise.

Lincoln Gordon, U.S. Ambassador to Brazil: The U.S. “eyes and ears” on the ground, Gordon was involved in overseeing covert operations, and reporting on and assessing the developments towards the launch of the coup.



1968: The Brazilian military regime lined up tanks in the center of Rio de Janeiro in a show of force.

CIA Agent Dan Mitrione: Hundreds of Brazilian military and police officers were trained in torture techniques by the CIA—specifically, by agent Dan Mitrione. Mitrione had been an Indiana cop, an FBI agent, and an adviser for the CIA in Latin America. He taught police how much electric shock to apply to prisoners without killing them. This systematic torture was referred to officially as “Scientific Methods to Extract Confessions and Obtain the Truth.” Mitrione tested his torture techniques on street kids and homeless beggars from the streets of Belo Horizonte, Brazil. Torture included electric shocks growing in intensity and sessions of “pau de arara” (suspension from a rod by the hands and feet). Many of these techniques would be replicated across the region through the U.S.-sponsored Operation Condor that spread a reign of terror against dissidents and rebels throughout South America (see American Crime Case #87: Operation Condor 1968-1980s: U.S.-Directed Campaign of Political Assassination and State Terror in Latin America).

In 2008, a former police intelligence agent provided testimony suggesting João Goulart—who had been overthrown in the coup—had been poisoned by Condor operatives in 1976.

Henry Luce and TIME magazine: TIME magazine published positive reports on the activities of the military regime as it carried out the elimination of political parties, and the implementation of salary controls that increased the hardship among Brazil’s working class.

Military leaders of the Brazilian coup: In addition to the crimes committed during and after the coup, Brazil’s ruthless military dictatorship became the “regional model” for the pro-U.S. military dictatorships of the Southern Cone to follow, and which worked together in Operation Condor. The Brazilian military’s “Doctrine of National Security” provided intellectual justification for unleashing the military dictatorships’ violence on the forces of opposition and resistance of their own countries who dared to speak out and resist.

THE ALIBI: The Brazilian military and right-wing sections of the ruling class, together with the U.S. imperialists, justified the coup by portraying Goulart’s government as a “socialist threat,” instigated by international communism.

BAsics from the talks and writings of Bob Avakian   

The essence of what exists in the U.S. is not democracy but capitalism-imperialism and political structures to enforce that capitalism-imperialism. What the U.S. spreads around the world is not democracy, but imperialism and political structures to enforce that imperialism.

—Bob Avakian, BAsics 1:3

ACTUAL MOTIVE: While the Goulart government was no ally of Cuba, Lyndon Johnson saw its refusal to join in isolating Cuba, as well as efforts such as organizing peasants in northeastern Brazil, as signs of a “leftist” government that couldn’t be tolerated.

For the U.S., stability and control of its “own backyard” has always been essential to maintaining its domination elsewhere in the world. Following World War 2, the struggles for national liberation developing in different parts of the Southern Cone of Latin America, given encouragement and support by the Cuban revolution and often aligned in some way with the Soviet Union, posed a strategic challenge.

The Brazilian coup came in the early stages of what the U.S. military saw as the necessary response—the development of a coordinated, regional counterinsurgency force, and strategy, capable of carrying out assassinations of guerrilla resistance fighters and their political allies anywhere in the region. In many ways, Brazil became a “model” for the other U.S.-backed military dictatorships that followed.

From the genocide in Gaza, to the growing threat of world war between nuclear powers, to escalating environmental devastation… the capitalist-imperialist system ruling over us is a horror for billions around the world and is tearing up the fabric of life on earth. Now the all-out battle within the U.S. ruling class, between fascist Republicans and war criminal Democrats, is coming to a head—likely during, or before, the coming elections—ripping society apart unlike anything since the Civil War. 

Bob Avakian (BA), revolutionary leader and author of the new communism, has developed a strategy to prepare for and make revolution. He’s scientifically analyzed that this is a rare time when an actual revolution has become more possible, and has laid out the sweeping vision, solid foundation and concrete blueprint for “what comes next,” in the Constitution for the New Socialist Republic in North America

The website follows and applies that leadership and is essential to all this. We post new materials from BA and curate his whole body of work. We apply the science he’s developed to analyze and expose every key event in society, every week. posts BA’s timely leadership for the revcoms (revolutionary communists), including his social media posts which break this down for people every week and sometimes more. We act as a guiding and connecting hub for the growing revcom movement nationwide: not just showing what’s being done, but going into what’s right and what’s wrong and rapidly learning—and recruiting new people into what has to be a rapidly growing force.

Put it this way: there will be no revolution unless this website not only “keeps going” but goes up to a whole different level!
