However, the OAS did approve (1965) the U.S. intervention in the Dominican Republic's civil war, though it refused a similar action during the Nicaraguan revolution (1979). Among the many conflicts handled by the council were those between Costa Rica and Nicaragua (1948, 1949, and 1955), when the Nicaraguan regime of Anastasio SomozaSomoza, Anastasio

A nearly five-decade issue for the OAS was its relationship with Cuba after the Cuban revolution (1959). In 1962, Cuba was formally suspended from the organization on charges of subversion. Two years later, a trade boycott was imposed on Cuba, but by the 1990s, practically all member nations except the United States had resumed trade and diplomatic relations with Cuba. In 2009, by which time the United States was the only American nation without relations with Cuba, the OAS's suspension of Cuba was ended, but Cuba, at least initially, rejected rejoining the OAS.
