GUANTANAMO BAY, CUBA - OCTOBER 22: (EDITORS NOTE: Image has been reviewed by the U.S. Military prior to transmission.) Razor wire and a guard tower stands at a closed section of the U.S. prison at Guantanamo Bay, also known as "Gitmo" on October 22, 2016 at the U.S. Naval Station at Guantanamo Bay, Cuba. The U.S. military's Joint Task Force Guantanamo is holding 60 detainees at the prison, down from a previous total of 780. In 2008 President Obama issued an executive order to close the prison, which has failed because of political opposition in the U.S.  (Photo by John Moore/Getty Images)
