One of these days Russia is going to ask for more than they expect. The next war will be so destructive that all sides will suffer almost total destruction. Idiots in Russia just don’t get it. Any WWIII will destroy most of the earth. There will be no winner.
Mutually Assured Destruction was a term invented by or for Robert McNamara. JFK had won the 1960 election largely on the meme that Eisenhower and his VP, Nixon, had allowed a "Missile Gap" to develop between the United States and the USSR.
In April of 1961, as the new SecDef, he asked for a briefing from the JCS and SAC detailing the "Gap."
They sat him down, and explained that the Missile Gap didn't exist. We had so many missiles and bombs, from ICBMs, SLBM, and B-52s in 24 hour orbit, down to tactical nukes from fighters, that police stations and Party headquarters buildings in towns of more than 10,000 had been had been targeted, just to use them all, and confirm that the USSR would never be able to mount an attack.
Here is the tippy top secret: Our intent was "Launch On Warning." If the CIA and the NSA came to the President with proof that the USSR was PLANNING an attack, (Remember, that by this time, we were watching every movement by satellite.), we would launch first. Within 2 hours, on the President's order. There is no point in nuking an empty silo. Estimates ran to 380,000,000 Russian dead, before one of their unreliable birds cleared a silo. The Russians knew that there was a finger on the Button, itching to vaporize the entire country. They never came close. It was always bluster, and back door subversion.
MacNamara was horrified. For the rest of his career, he spent every waking moment trying to convince the President not to listen to the CIA. He came up with MAD, and put it out, trying to pressure the rest of the country to reject 'launch on warning.' You hear a lot about MAD, still, as if the Feds would have let NYC vanish as a justification for shooting back.
Or more likely, the outcome will be pre-determined and we will find out that we have been completely sold out by the Washington Establishment. The "war" will have been only for show.
