The U.S. has signed a deal with the Taliban aimed at drawing down its military presence and ending its 18-year war in Afghanistan. The long-anticipated deal comes after a year and a half of negotiations and following a week-long partial truce. Officials hope the accord will set the stage for a more detailed peace plan that creates a power-sharing arrangement and lasting ceasefire, but the deal did not include a key player: the U.S.-backed Afghanistan government. The Taliban has long refused to speak to the government, calling it a “puppet regime.” Under the deal, nearly 5,000 of the 12,000 U.S. troops still in Afghanistan will leave the country in 135 days. The rest of the troops will withdraw 14 months later, if the Taliban comply with the terms of the agreement. We discuss details of the deal with Azmat Khan, award-winning investigative reporter, a New York Times Magazine contributing writer and a Future of War fellow at New America.
