The U.S. presence in Guantanamo is against the will of the Cuban government and they consider it as an illegal occupation of the area by the United States. The U.S. government believes it is in compliance with a treaty signed by both governments, however the Cuban government strongly denounces the treaty on grounds that article 52 of the 1969 Vienna Convention on the Law of Treaties declares a treaty void if its conclusion has been procured by the threat or use of force (see below).

U.S. Naval Station Guantanamo Bay, which covers 116 km² (approx. 45 sq miles), is sometimes abbreviated as GTMO or "Gitmo". It was established in 1898, when the United States obtained control of Cuba from Spain at the end of the Spanish-American War, following the 1898 invasion of Guantánamo Bay. The U.S. government obtained a perpetual lease that began on February 23, 1903, from Tomás Estrada Palma, an American citizen, who became the first President of Cuba. The newly formed American protectorate incorporated the Platt Amendment in the Cuban Constitution. The Cuban-American Treaty held, among other things, that the United States, for the purposes of operating coaling and naval stations, has "complete jurisdiction and control" of the Guantánamo Bay, while the Republic of Cuba is recognized to retain ultimate sovereignty.
In 1905, in part because of the Platt Amendment, there was an uprising to which the United States responded by occupying Cuba for three years. A 1934 treaty reaffirming the lease granted Cuba and her trading partners free access through the bay, modified the lease payment from $2,000 in U.S. gold coins per year, to the 1934 equivalent value of $4,085 in U.S. Treasury Dollars, and added a requirement that termination of the lease requires the consent of both governments, or the abandonment of the base property by the United States.
With over 9,500 U.S. troops, <4> Guantánamo Bay is the only U.S. base in operation on Communist soil, as of 2006.
Since coming to power, Fidel Castro has only cashed one rent check, while steadfastly refusing to cash any others, because he views the lease as illegitimate. Although diplomatic relations do not exist between the two countries, the United States has agreed to return fugitives from Cuban law to Cuban authorities, and Cuba agreed to return fugitives from U.S. law, for offenses committed in Guantánamo Bay, to U.S. authorities.
