ARNOLD OLIVER – More than five years ago a soldier named Bowe Bergdahl left his U.S. Army unit in Afghanistan. He was captured, imprisoned in brutal conditions for five years, and finally released in a prisoner exchange in 2014. The Army is now considering whether he should be court-martialed for desertion and other crimes. Bergdahl’s case needs to be understood, not only in terms of his actions, but also what is known about the psychology of war. What we have learned ought to give pause to those eager to send young people off to fight and die. To explain, let’s review some of the research on the psychological stressors relevant to the Iraq and Afghanistan wars.
