After the Cuban Revolution of 1959, relations deteriorated rapidly leading to the Bay of Pigs Invasion, the Cuban Missile Crisis, and successive US attempts to destabilize the island, based upon Cold War fears of the Soviet threat. The U.S. invaded and occupied Haiti for 19 years (1915–34), subsequently dominating the Haitian economy through aid and loan repayments. The U.S. invaded Haiti again in 1994 and in 2004 were accused by CARICOM of arranging a coup d'état to remove elected Haitian leader Jean-Bertrand Aristide. In 1965, 23,000 US troops were sent to the Dominican Republic to quash a local uprising against military rule (see Dominican Civil War). President Lyndon Johnson had ordered the invasion to stem what he deemed to be a "Communist threat." However, the mission appeared ambiguous and was roundly condemned throughout the hemisphere as a return to gunboat diplomacy. In 1983, the US invaded Grenada to remove populist left-wing leader Maurice Bishop. The US maintains a naval military base in Cuba at Guantanamo Bay. The base is one of five unified commands whose "area of responsibility" is Latin America and the Caribbean. The command is headquartered in Miami, Florida.
