Why did no one tell me.
Briefly, in 1983 at the height of East/West tension, the reds shot a Korean jumbo jet down into the China sea. The Ruskies through their newly launched statalite system detected missiles lifting off from the USA and coming their way.
They went into retaliatory mode. Counting down to zero even. But the Hero of the piece, in agonies of conscience, said NO and did not turn his key.
Later analysis reckoned half the population of the USA would have died. Ditto Russia. The further retaliatory responses would have meant hundreds if not thousands of atomic IBM's launching. The resultant radiation, ash and dust clouds would have turned the Earth into a totally barren desert never to return.
Turned out to be a glitch in the system but it was never discovered where.
Hail a very modest man.
Double phew ! Sleep well.
