Although despising Argentina's right wing military junta, Castro supported them in the 1982 Falklands War against the United Kingdom and offered military aid to the Argentinians. Castro supported the leftist New Jewel Movement that seized power in Grenada in 1979, sent doctors, teachers, and technicians to aid the country's development, and befriended the Grenadine President Maurice Bishop. When Bishop was murdered in a Soviet-backed coup by hardline Marxist Bernard Coard in October 1983, Castro cautiously continued supporting Grenada's government. However, the U.S. used the coup as a basis for invading the island. Cuban construction workers died in the conflict, with Castro denouncing the invasion and comparing the U.S. to Nazi Germany. Castro feared a U.S. invasion of Nicaragua and sent Arnaldo Ochoa to train the governing Sandinistas in guerrilla warfare, but received little support from the Soviet Union.
