I started reading this book as research, trying to understand post-traumatic stress disorder more thoroughly for the book I am writing. I think this is an excellent piece of work. Lt. Col. Grossman, a psychologist as well as a soldier, explains how overcoming the natural, inborn human resistance to killing (which is considerable) causes more PTSD than anything else in warfare. His sobering thoughts on how techniques of conditioning soldiers to kill were more effective in recent years than in any war in history (Vietnam being the first example), and how we are, unintentionally perhaps, applying those techniques to our society, sparked an article for my column: http://witchesandpagans.com/Pagan-Culture-Blogs/on-killing.html. I think everyone who wants to understand war, soldiers, and killing, should read this book. ‘Nuff said.
