Question

Why is guantanamo bay in Cuba? what is the U.S affiliation to Cuba?

Answer 1

The United States assumed territorial control over Guantánamo Bay under the 1903 Cuban-American Treaty, which granted the United States a perpetual lease of the area without the Cuban Government reacting. The current Cuban government considers the U.S. presence in Guantánamo to be illegal, arguing that the Cuban-American Treaty violates Article 52 of the 1969 Vienna Convention on the Law of Treaties, which declares a treaty void if its conclusion has been procured by the threat or use of force in violation of international law. Article 4 of the same document states that Vienna Convention on the Law of Treaties shall not be retroactively applied to any treaties made before itself.[1]

Answer 2

It was leased very cheaply to the US government to use as a refueling depot. Cubans consider that the agreement has been violated because of the change of use and they deplore what is going on there.
