In 1980–81, he was posted to El Salvador during the first years of that country's brutal 12-year civil war. He was harshly critical of the Salvadorian government and accused the military and paramilitaries (widely alleged to have close ties) of committing widespread atrocities against civilians, many of which were later factually confirmed. He once called prominent military figure Roberto D'Aubuisson a "pathological killer". D'Aubuisson was widely suspected of collaboration with death squad killings including the assassination of Archbishop Óscar Romero. He also accused José Napoleón Duarte, El Salvador's President from 1984 to 1989 of being a CIA asset.
