Most of us heard some portion of the president's 2002 speech outlining the doctrine of pre-emption. It was a huge shift in U.S. policy, and kicked up an enormous debate. But for the graduating class of West Point that year, it changed their lives. President Bush delivered that speech at the United States Military Academy, and every new officer listening was sure to prepare for war. Bill Murphy, Jr., went back and talked with many of the members of the class of 2002, and their friends and families. He tells their stories in a new book, In A Time of War. On the 7th anniversary of 9/11, we'll talk with Bill, and a member of the class of 2002. As well as the widow of another member whose story is told in the book. If you are — or were — in the military, how did 9/11 change your life?
