It now appears that — barring some truly exceptional circumstances — Barack Obama has made his last decision regarding Afghanistan as president of the United States. The current force of about 10,000 U.S. service members will remain through the end of 2016, when it will quickly draw down to a force of about 5,500. The next president will take office with a force in Kabul and relatively small detachments on the airfields at Bagram, Jalalabad and Kandahar.
