Human Killing Machines offers a comparative analysis of the indoctrination methods used to produce violence in the famous Milgram and Zimbardo psychological experiments, as well as Iran, Nazi Germany, Al Qaeda, and Abu Ghraib. Based on these findings, specific policy recommendations are made for how we can begin to reform the U.S. military and increase its accountability, shake Al Qaeda terroristsO commitment to their missions, and reverse course on Iran to bring the oppressive regime down from the inside.
