Posts mark the anniversary of September 26, 1983, when Soviet officer Stanislav Petrov correctly judged a reported US missile launch alert to be a false alarm and did not escalate, an act often credited with helping avoid nuclear war. Users are sharing the Vox article and reflecting on how close the world came to catastrophe, Petrov's calm judgment, and the broader risks of Cold War-era nuclear early-warning systems. The posts are largely commemorative in tone, honoring a little-known figure.
