In 1964, Brazil's democratically elected, left-wing government was ousted in a coup and replaced by a military junta. The Johnson administration quickly recognized the new government. The U.S. press and members of Congress were nearly unanimous in their support of the “revolution” and the coup leaders' anticommunist agenda.

Few Americans were aware of the human rights abuses perpetrated by Brazil's new regime. By 1969, a small group of academics, clergy, Brazilian exiles, and political activists had begun to educate the American public about the violent repression in Brazil and mobilize opposition to the dictatorship. By 1974, most informed political activists in the United States associated the Brazilian government with its torture chambers. In We Cannot Remain Silent, James N. Green analyzes the U.S. grassroots activities against torture in Brazil and the ways those efforts helped to create a new discourse about human-rights violations in Latin America. He explains how the campaign against Brazil's dictatorship laid the groundwork for subsequent U.S. movements against human rights abuses in Chile, Uruguay, Argentina, and Central America.
