Nonetheless, yes, we're still on the brink of something gloomy. The movie is quite good, and would massively gain from spinoffs showing what happens in realtime in other countries too.
From https://en.wikipedia.org/wiki/Stanislav_Petrov :
“His subsequent decision to disobey orders, against Soviet military protocol, is credited with having prevented an erroneous retaliatory nuclear attack on the United States and its NATO allies that would have likely resulted in a large-scale nuclear war.”
I thought it was excellent. And I was disappointed with the ending, but I also don't know that any other ending would have been better. The point of the ending to me is that literally no one on earth knows what would happen beyond that point.
Our very civilization is Schrodinger's box that's a few mins away from being opened.
The very last scene, which I won’t give away but involves buses, is one of the most haunting things I have ever seen.
Spoilers ahead, in case you decide to watch this bleak 2 hour waste of time:
"Oooh, nothing works, ooohh, we're going to die". This should've been a 15 minute YouTube video, not a movie.
I found it excellent.
I mean, to be fair, this is the actual situation with nuclear weapons.
There's nothing you can do. You just... die. Everyone. There's no magic bullshit the US can pull out of it's ass to prevent it. One singular nuclear warhead can be enough to eradicate the entire population in the US.
How big would this warhead be? "One singular nuclear warhead" wasn't enough to eradicate the entire populations of Hiroshima and Nagasaki, much less Japan.
If you think that wouldn’t happen, then you have to believe the US would accept a nuclear strike on one of its population centers and respond with conventional force and/or law enforcement. I am not confident!
Modern nuclear strategy does not aim to use nuclear weapons to immediately kill everybody in the US. We moved away from really big payloads towards smaller independent payloads with better targeting precision, along with greatly reducing the size of the stockpile.
