Four and a half years after the war in Iraq began, we discuss the toll the war is taking on American soldiers, both on the frontlines and here at home. Ashley Gilbertson’s new book of photographs of the US-led invasion of Iraq is called Whiskey Tango Foxtrot. Nina Berman has gathered images and stories of injured American soldiers in her book, Purple Hearts: Back from Iraq.
