This weekend in a series of tweets, President Trump both disclosed and scrapped secret talks with the Taliban in Camp David. Of course, the Taliban did not perpetrate 9/11. But they did offer safe haven in Afghanistan to Al Qaeda, whose hijackers turned passenger airplanes into bombs in the most deadly act of terrorism on US soil.

A few weeks later, America invaded the central Asian crossroads whose history has been one of occupation. "Today we focus on Afghanistan, but the battle is broader," President George Bush said at the time. "Every nation has a choice to make. In this conflict, there is no neutral ground. If any government sponsors the outlaws and killers of innocence, they have become outlaws and murderers themselves. And they will take that lonely path at their own peril." The whole world understood.

Or, almost the whole world. One country that was unclear about the US mission and its motives was Afghanistan itself. According to a November 2010 study by the International Council on Security and Development, during the height of fighting in Helmand and Kandahar, 92 percent of southern Afghan males there had never heard of 9/11. The staggering statistic caught the eye of Stars & Stripes reporter J.P. Lawrence — himself a Iraq-war veteran; to mark the anniversary of 9/11 he decided to conduct his own survey last year. In this podcast extra, he and Bob talk about why misconceptions persist about the 18-year war in Afghanistan.
