Col. Erik Goepner, currently serving as a military fellow at the Center for Strategic and International Studies, argues that the Afghan counterinsurgency was all-but-doomed before U.S. troops ever landed there. The reason, he writes, is “the high rate of mental disorders” in Afghanistan and other fragile states. Pervasive depression and post-traumatic stress disorder leads to a sense of "learned helplessness" among the people. And that makes it next-to-impossible to build up the country’s economy and government.
