United States troops leave Cuba, with the exception of Guantanamo Bay Naval Base, after being there since the Spanish–American War.

Cuba, officially the Republic of Cuba, is an island country in the Caribbean, comprising the island of Cuba, Isla de la Juventud, and 4,195 islands, islets and cays surrounding the main island. It is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both Florida and the Bahamas, west of Hispaniola, and north of Jamaica and the Cayman Islands. Havana is the largest city and capital. Cuba is the third-most populous country in the Caribbean after Haiti and the Dominican Republic, with about 10 million inhabitants. It is the largest country in the Caribbean by area.

Guantanamo Bay Naval Base, officially known as Naval Station Guantanamo Bay or NSGB, is a United States military base located on 45 square miles (117 km²) of land and water on the shore of Guantánamo Bay at the southeastern end of Cuba. It has been leased from Cuba to the U.S., without expiry, since 1903 as a coaling station and naval base. It is the oldest overseas American naval base. Since 1974, the U.S. has paid the Cuban government an annual sum equivalent to $4,085 in 1934 dollars to lease the bay. The lease was previously $2,000 per year until 1934, when it was set to match the value of gold in dollars.

The Spanish–American War was fought between Spain and the United States in 1898. It began with the sinking of the USS Maine in Havana Harbor in Cuba, and resulted in the U.S. acquiring sovereignty over Puerto Rico, Guam, and the Philippines, and establishing a protectorate over Cuba. It represented U.S. intervention in the Cuban War of Independence and Philippine Revolution, with the latter later leading to the Philippine–American War. The Spanish–American War brought an end to almost four centuries of Spanish presence in the Americas, Asia, and the Pacific; the United States meanwhile not only became a major world power, but also gained several island possessions spanning the globe, which provoked rancorous debate over the wisdom of expansionism.
