One more thermonuclear anecdote from Wikipedia:
When General LeMay was named vice chief of staff of the Air Force in 1957, General Power became commander in chief of SAC and was promoted to four-star rank. But, although Power was LeMay's protégé, LeMay himself was quoted as privately saying that Power was mentally "not stable" and a "sadist".
When RAND proposed a counterforce strategy, which would require SAC to restrain itself from striking Soviet cities in the beginning of a war, Power countered with:
Restraint? Why are you so concerned with saving their lives? The whole idea is to kill the bastards. At the end of the war if there are two Americans and one Russian left alive, we win!
Stanislav Petrov is a rather famous person (of course only on Lesswrong, not in the real world).
But there is another Russian who saved the world: Vasili Alexandrovich Arkhipov.
On this day in 1962, at the height of the Cuban Missile Crisis Vasili Arkhipov prevented the launch of a nuclear torpedo and thus a possible nuclear war.
It's strange that Petrov attracts much more attention than Arkhipov. E.g. googling "Stanislav Petrov" produces 101.000 results, "Vasili Arkhipov" only 9.040 results. By contrast searching for "Britney Spears" generates about 295.000.000 results. Sorta depressing.
Anyway, let this day be the Vasili Arkhipov Day.
