I can't be the only one that thinks it's inevitable based on the anecdotes.
MAD really seemed to require you unleash everything and generally if the others did you would be targeting a lot of empty silos in the middle of nowhere. At least those in the Midwest.
They interviewed the American and Russians (they get to watch) folks at the site.
Young reporter once asked how the Russians could be sure what silo it is if they’re escorted by Americans the whole time.
The American commander paused and said “My Russian counterpart here probably knows this location as well as I do.”
The Russian who previously only used a translator burst out in a smile and belly laugh.
The plan was always to get them off the ground before most of the enemy missiles hit. And perhaps to withstand a nearby attack, as targeting tech in the 60s was not very accurate yet. But these days that won't work anymore.
