I came to Cuba to attend the 4th fourth International Seminar for Peace and the Abolition of Foreign Military Bases and to advocate for the closure of Guantanamo Bay. This call comes almost 14 years after the prison was opened, after Obama repeatedly stated his intention to close it, and while 107 prisoners still languish behind bars. The letter below is one I wrote in response to the absence of American Muslim voices in the movement to close Guantanamo Bay, while occupying a camp site close to the gates of the U.S. Naval Base that houses this notorious prison.
