To build naval protection against rivals as the United States increased trade with Asia and Latin America.
During World War II and the Cold War, the United States establishes multiple military bases to build naval protection against rivals as the United States increased trade with Asia and Latin America. A curious example is the Easter Island, which was a U.S. military base and offered protection to the locals but was completely unknown to the Soviet union. Strategic location and commerce treaties helped the U.S. to be supplied with raw material from Asia and Latin America.
