Why does the United States government have a prison camp in Cuba?
The prison is on the USA base at Guantanamo. The USA has had a lease on property there since 1903 and has used it for many purposes over the years. For a very good history of the base, see this other Answerbag question and answer: http://www.answerbag.com/q_view.php/21291 — If the link doesn’t work (it did for me when I tried it), just search Answerbag for ‘Guantanamo’; it will be the first question in the results list.
