U.S. military action in Afghanistan will be over next year. "Blocked by Congress from releasing or transferring many of the remaining 164 detainees and able to try only a small number of them, administration officials are examining whether the withdrawal of U.S. troops at the end of 2014 could open the door for some to challenge the legal authority of the United States to continue to imprison them," The Washington Post reports. At issue is whether the authority to detain prisoners as belligerents and enemy combatants expires if the "hot war" is over.
