In the minds of far too many Americans, the wars in Iraq and Afghanistan are little more than ideas: words and phrases bandied about by politicians, dinner party talking points for the moderately informed, momentary segments blipped above ticker stats on cable news shows. Yet no matter how far away those zones of conflict may seem, they are, in fact, quite real and quite consequential. And the men and women who've actually served on the front lines are becoming all too aware of an even more brutal truth: They have to keep going back.Fortunately, there are some people who are committed to telling their stories. The photographer Peter van Agtmael was periodically embedded in Iraq and Afghanistan from 2006 to 2008, during which time he befriended a number of soldiers and attempted to convey, through a series of arresting images, the range of emotional, psychological, and physical experiences of those troops. The harrowing images reveal a world about which most of us dedicate too little in the way of consideration, and now fill the pages of his book Second Tour: Hope I Don't Die.We're proud to show a few of those photographs here, courtesy of Magnum Photos.
