After his downfall, Noriega served a 17-year drug sentence in the United States, then was sent to face charges in France. He spent all but the last few months of his final years in a Panamanian prison for murder of political opponents during his 1983-89 regime. He accused Washington of a conspiracy to keep him behind bars and tied his legal troubles to his refusal to cooperate with a U.S. plan aimed at toppling Nicaragua’s leftist Sandinista government in the 1980s.
