Petrov's decision to disregard the erroneous radar warnings is credited with having prevented a retaliatory nuclear attack on the United States and its NATO allies that could have resulted in large-scale nuclear war.
Stanislav Petrov had the courage to disobey his military orders (to "launch on warning") because of his personal knowledge and convictions.
Also, there is a real risk that North Korea could retaliate by shipping a hidden nuclear bomb as normal cargo by sea to America, and explode the nuclear bomb once the freighter reached the US port.
Worse still, it would not even be clear which nation/group sent the nuclear bomb.
So if America starts a war against North Korea, all bets are off.
These two men are the only two people on earth who could single-handedly start a nuclear World War III and thus annihilate all life on our planet.
Our survival will depend upon whether love, brotherhood, and peace can overcome hate, nationalism, and war.
