Naval Base

Guantanamo Bay Naval Base at the southeastern end of Cuba has been used by the United States Navy for more than a century. The US controls the land on both sides of the southern part of Guantanamo Bay under a lease set up in the wake of the 1898 Spanish-American War. The Cuban government denounces the lease on grounds that article 52 of the 1969 Vienna Convention on the Law of Treaties voids treaties procured by force or its threatened use.

Since 2001, the Naval Base contains a controversial detainment camp for militant combatants collected from Afghanistan and later from Iraq, that the US says are not covered by the Geneva Convention.
