Ah, nuclear weapons!  Having grown up while the Cold War was still going strong, I can almost think about nuclear bombs with a sentimental eye — though the threat of nuclear terrorism is still a possibility, we’re much further away from complete annihilation than we were back in my childhood.  I still remember being frightened as a child at the possibility that someone, somewhere, for reasons I would never understand, might start the “big one” without warning.
