Who is representing the United States in today's tough fights in Iraq, Afghanistan, and elsewhere? What are their backgrounds? What motivates them? How exactly are they conducting themselves? Pulitzer-winning New York Times writer Chris Hedges says members of the U.S. armed forces are mostly "poor kids from Mississippi or Alabama or Texas who could not get a decent job or health insurance and joined the Army because it was all we offered them." Filmmaker Michael Moore argues that our soldiers are mainly dispossessed inner-city left-outs, who are now occupying and terrorizing Iraq. What is the truth? How representative were the undisciplined MPs of Abu Ghraib's night shift? In the last year, Karl Zinsmeister has published one book describing American military operations in Iraq during the hot war and a second book that chronicles the guerilla war and reconstruction phase-with both books based on firsthand observation of U.S. combat troops on the streets of Iraq over many weeks. He will give a slide-illustrated talk on his findings, a kind of taxonomy of today's American soldier, then take questions and sign his latest book Dawn over Baghdad: How the U.S. Military Is Using Bullets and Ballots to Remake Iraq.
