Reagan's primary concern in Latin America, though, was Nicaragua. In 1979, President Carter had supported the Socialist Sandinista movement when it overthrew Nicaragua's dictator. Reagan, however, vehemently opposed the Sandinistas's claim to power and the organization's Communist ties. In 1981, Reagan authorized the Central Intelligence Agency to train an army of 10,000 Nicaraguan "freedom fighters," or Contras, to fight the Sandinistas. Congress angry at this, did not wnat another Vietnam. Passed the Boland Amend. to ban US assistance to contras.
