Another suggestion, mostly because the context around it is interesting; Deadline, a short story about the atomic bomb written in 1943 that was good enough at guessing the endgame that the FBI almost killed the story.
There's a whole set of speculative fiction on that topic that's especially terrifying. There's Fermi and Frost which I hoped we might get to, and a BBC miniseries called Threads along similar lines. These ones hit hard because they nearly could have been reality. Along that same vein I guess you could throw Dr. Strangelove into the mix.
