“ I would wish this book could take the form of a plea for everlasting peace, a plea from one who knows... Or it would be fine to confirm the odd beliefs about war: it's horrible, but it's a crucible of men and events and, in the end, it makes more of a man out of you.But, still, none of these notions seems right. Men are killed, dead human beings are heavy and awkward to carry, things smell different in Vietnam, soldiers are afraid and often brave, drill sergeants are boors, some men think the war is proper and just and others don't and most don't care. Is that the stuff for a morality lesson, even for a theme?Do dreams offer lessons? Do nightmares have themes, do we awaken and analyze them and live our lives and advise others as a result? Can the foot soldier teach anything important about war, merely for having been there? I think not. He can tell war stories. ”
