Since the Cuban Revolution of 1959, the Cuban communist government has consistently protested against the U.S. presence on Cuban soil and called it "illegal" under international law, alleging that the base "was imposed on Cuba by force." Since 2002, the naval base has contained a military prison, for alleged unlawful combatants captured in Afghanistan, Iraq, and other places during the War on terror. Cases of torture of prisoners by the U.S. military, and their denial of protection under the Geneva Conventions, have been criticized.
