John Pilger, Do You Remember Vietnam? (1978) and Vietnam: The Last Battle (1995)
How is what we did in Vietnam any different from what the Nazis did in Europe? Recall that we had a mass concentration-camp policy (using bombing to drive peasants into "strategic hamlets") before you reject this comparison out of hand. Include chemical warfare, total ecological destruction, and Kissinger's infamous order: "Anything that flies against anything that moves."
