I read today that Robert S. McNamara is dead. Kaplan's piece in Slate gives a reasonable account of what made him such a pivotal figure; I can't say the same of his counterpart writing for Salon, whose portrayal of the broader history of the Vietnam War is much, much weaker than his stridently polar conclusions.
Perhaps it is time to watch Fog of War again. I definitely won't go as far as to re-read In Retrospect.
