Despite the fact that Cuba regained sovereignty over most of its territory in 1934, the US maintained authority over Guantanamo Bay. Although the lease was set to last for 99 years, there are still questions regarding its expiration date because it began on either May 11 or February 23.
The continued maintenance of a military detention center by the US in Guantanamo Bay has created political unrest and disagreements because it is widely seen as a violation of international law. Numerous human rights groups have criticized the facility for its harsh circumstances, detention without charge, and alleged human rights abuses.
The presence of Guantanamo Bay has also strained US-Cuba relations, and many nations have called for its closure. The Cuban government has consistently demanded that the military installation be closed and its territory returned in accordance with international law and the original lease agreement, despite attempts to negotiate a solution with the US.
