From 1981 to 1985 Negroponte was US ambassador to Honduras. During his tenure, he oversaw the growth of military aid to Honduras from $4 million to $77.4 million a year. At the time, Honduras was ruled by an elected but heavily militarily-influenced government. According to The New York Times, Negroponte was responsible for "carrying out the covert strategy of the Reagan administration to crush the Sandinistas government in Nicaragua." Critics say that during his ambassadorship, human rights violations in Honduras became systematic.
Negroponte supervised the construction of the El Aguacate air base where Nicaraguan Contras were trained by the US, and which critics say was used as a secret detention and torture center during the 1980s. In August 2001, excavations at the base discovered 185 corpses, including two Americans, who are thought to have been killed and buried at the site.
I have no snarky comment for this, a truly dark day.
