Guantánamo Bay

Guantánamo Bay is a large natural harbor in southeastern Cuba and the site of the oldest overseas U.S. naval base still operating. Cuba and the United States signed agreements in February and July 1903 granting the United States control over specified land and water for naval and coaling purposes while recognizing Cuba's ultimate sovereignty. The arrangement emerged under the unequal conditions created by the Platt Amendment after the Spanish-American War and the first U.S. occupation of Cuba.

A 1934 treaty ended most provisions associated with the Platt Amendment but preserved the Guantánamo lease unless both governments agreed to change it or the United States abandoned the base. After 1959, Fidel Castro's government rejected the legitimacy of the arrangement and generally refused to cash the annual rent checks, while the United States maintained that the treaties remained valid. The dispute embodies two truths at once: the base rests on signed agreements, and those agreements were negotiated when Cuban sovereignty was heavily constrained by American power.

The base gained a different meaning after the September 11, 2001 attacks. The first detainees in the U.S. “war on terror” arrived on January 11, 2002, and hundreds of men were eventually held there. Many spent years without criminal trial. Investigations, court cases, and testimony documented abusive interrogation practices, including treatment widely recognized as torture. Supreme Court decisions established that detainees could challenge their detention, rejecting the idea that the base existed entirely beyond constitutional and judicial review.

The detention center remained open long after several U.S. presidents expressed a desire to close it. Its prisoner population fell dramatically, reaching 15 men after transfers announced in January 2025, but unresolved military commission cases and restrictions imposed by Congress complicated closure. The Cuban government invokes Guantánamo as evidence of American domination while denying comparable scrutiny of its own prisons. A consistent human-rights standard requires condemning arbitrary detention and abuse whether committed by Washington or Havana.
