My discomfort with the use of Nazis in this discussion is the motives are different. The Nazis wanted "lebensraum." A nuclear holocaust is kind of the opposite of that. "Holocaust" is a term used regularly in discussing nuclear warfare, minus the Nazis; I think this is because the Nazis were so goddamn methodical about it while nuclear armageddon is pretty much a game of 52 pickup. Evil is as evil does and both moves are unspeakably evil, but at least the Nazis were evil and practical. "Hard to make a lampshade out of ashes," he said grimly. And the theory about limited death kinda went out the door the minute we had ICBMs. I'm not sure when, exactly, arsenals expanded to the point where total ecosystem destruction was a probability, but I reckon it was back in the '60s. Nobody seriously thought anyone would survive a negative outcome of the Cuban Missile Crisis. Which is an argument for MAD, crazy as it is. I'm going to guess you're younger than me.
