It is also the only naval base in a communist country and the only one that has no political affiliation with the United States. With 45 miles of naval infrastructure, Guantanamo Bay is often called the "Pearl Harbor of the Atlantic." Due to its remote location and jurisdiction, Guantanamo Bay has been deemed by one United States government official as the “legal equivalent of outer space”. History of Guantanamo Bay At the wake of the 20th century, the U.S. formally leased this 45 square mile parcel from newly independent Cuba to use as a fueling station. The lease was renewed in 1934 under Fulgencio Batista and President Franklin D. Roosevelt's administration. The agreement required the consent of both parties should either want to withdraw; that is, reconsider U.S. occupation of the base. Diplomatic relations between the U.S. and Cuba were severed in January of 1961. In hopes the U.S. will forfeit the base, Cuba no longer accepts the $5,000 annual American rent. In 2002, Cuba officially requested that Guantanamo Bay be returned. Interpretation of the 1934 mutual consent agreement differs, causing frequent squabbles between the two countries. In 1964, Fidel Castro cut off the base’s water supply in response to the U.S. government fining Cubans for fishing near Florida. As a result, Guantanamo Bay is self-sufficient and produces its own water and electricity. The naval base itself is divided into two functioning areas on either side of the bay. The east side of the bay is the main base, and the airfield occupies the west side. Today, both sides of the base’s 17-mile fence line are patrolled by U.S. Marines and Cuban militiamen. During the 1990s, social upheaval in Haiti brought over 30,000 Haitian refugees to Guantanamo Bay. In 1994, the base provided humanitarian services to thousands of migrants during Operation Sea Signal. That year, civilian employees and their families were evacuated from the base to accommodate the influx of migrants. The migrant population climbed upwards of 40,000. By 1996, the Haitian and Cuban refugees had filtered out, and family members of the military were allowed to return. Ever since, Guantanamo Bay sees a small, steady migrant population of about 40 people each year. Geography and Land Use of Guantanamo Bay The bay itself is a 12-mile long north-south indentation and is six miles across. Islands, peninsulas, and coves can be found on the east side of the bay. The Guantanamo Valley lies west of the bay along the Sierra Maestra. The lowlands on the west side are adorned in mangroves. Its flat nature makes it ideal for Guantanamo’s airfield. Similar to many American towns, Guantanamo Bay is furnished with subdivisions, baseball fields, and chain restaurants. Roughly 10,000 people reside there, 4,000 of which are in the U.S. military. The remaining residents are family members of the military, local Cuban support staff, and laborers from neighboring countries. There is a hospital, dental clinic, and a meteorologic and oceanographic command station. In 2005, four 262-foot tall wind turbines were constructed on John Paul Jones Hill, the highest point on the base. During the windiest months, they provide the base with about a quarter of the power it consumes. Since the sharp population rise in 2002 of military and support personnel, Guantanamo Bay boasts a golf course and an outdoor theater. There is also a school, but with so few kids that sports teams play against groups of local firefighters and hospital workers. Separated from the base by cacti and elevated landforms, residential Guantanamo Bay bears many similarities to suburban America. Guantanamo Bay as Detention Center Its true nature and inner workings are somewhat elusive to the American public and are under constant scrutiny. One can only speculate on the future of Guantanamo Bay and as history suggests, its utility and habitation are ever-changing.
