“The Vietnam war,” Reich wrote in The Greening of America, “represents a form of madness in which logic is carried to fantastic extremes.” He had a point.

Enemy body counts are one very limited metric in war, seductive because they’re simply quantifiable, and in this case grossly exaggerated as well.
