Most of my suggestions about Vietnam books focus on the military aspects of the war. However, I was remiss in not mentioning Norman Podhoretz’s splendid Why We Were in Vietnam, which does an especially good job of explaining the morality of the decision to undertake the enterprise. Indeed, for most interested readers, this is the place to start. Then a reader might look at Guenter Lewy’s America in Vietnam, upon which I relied heavily in my critiques of Kerry.
