Until then, however, his administration must continue the progress it has made in recent months toward reducing the inmate population at the facility. In the context of the global war on terror the number of remaining detainees is small, and most of them pose no threat to our national security. Those who were actively involved as leaders of terrorist organizations have long since been replaced, and after more than a decade in captivity they've likely lost their influence along with whatever terrorist skills they once may have possessed. They've been physically and psychologically upended, ground down and debilitated. Experience now shows that detainees can be repatriated without putting us at risk. Meanwhile Guantanamo remains as a great moral stain on everything that this country stands for. It needs to be closed as soon as possible; it should have been closed long ago.
