President Barack Obama finally broke his long silence on Tuesday on the need to close Guantanamo. Echoing comments he made four years ago -- when, on his second day in office he promised to close the facility within a year -- he said "Guantanamo is not necessary to keep America safe. It is expensive. It is inefficient.... It needs to be closed." Welcome words, but it's unlikely they will brighten the day of the 100 men currently on hunger strike at the facility.
