Andrew Bacevich is a man on a journey -- as he himself is the first to admit. A cultural conservative, a former contributor to such magazines as the Weekly Standard and the National Review, a former Bush Fellow at the American Academy in Berlin, he discovered sometime in the 1990s that his potential conservative allies on foreign policy had fallen in love with the idea of the American military and its imagined awesome power to change the world. They had jumped the tracks and left him behind. A professed cold warrior, in those years he took a new look at our American past -- and he's not stopped looking, or reconsidering, since.
