Stanislav Petrov died this past spring at 77, but his death was only recently announced. You may or may not know who he was, and almost guaranteed would not have known you owe him your life just by seeing his picture. (You probably DO know the song that was inspired by Petrov's historical act of bravery.)
Back in 1983, as a Russian military officer, his rational thinking, courage, and steady nerves averted a nuclear war with the United States over a computer glitch. Juxtapose that with the entitled, arrogant, bloviating, military-duty-shirking fuck-face who stood up a few days ago at the United Nations, called another, no less insane leader childish, school yard names, and threatened to "totally destroy" another country (along with, I presume, all the innocent people in it.)
Bringing with it, of course, the mutually assured death of hundreds of thousands, if not millions of people in South Korea and Japan (North Korea's conventional weapons alone would flatten Seoul, the world's second largest city, before anything could be done about it), along with the likely demise of thousands of U.S. service people. Not that he cares. Because he can't get past how cool and clever he thinks he looks when he's acting the tough guy because he knows he's untouchable. Sniveling POS man-children who discuss dick size and how to sexually assault women on a national stage usually roll that way.
Stanislav Petrov was a MAN. Steady at the wheel. A true leader. A person who literally saved the world (given the size of the nuclear arsenals in the USA and USSR back then, this is not hyperbole), and never sought fame because of it.
So remember this face.
Next time you see some frightened, cowardly person carrying on with great wisdom about how we have to "take out North Korea before they strike us", be reminded that THIS man had far more reason to fear the U.S. than the U.S. has to fear North Korea, and still chose to potentially sacrifice himself and his country rather than have the world destroyed over a mistake.
Rest in peace, Mr. Petrov, and thank you for your service.
