>>63851878 (OP)It's definitly not going to end the world, nuclear winter was a fearmongering hypothesis made up by anti-nuclear activists to try and create so much backlash against nukes to completely defund them. Whether that is a good thing or not I leave up to you to decide, personaly I say it was good since nukes are gay and ruined the good old conventional wars.
The majority of humanity would survive in a complete nuclear exchange as they would only be used to target reinforced underground military bases in bum-fuck nowhere and population centers, meaning that the ones producing food and actually contributing to society would survive, though with a potentially worsened harvest due to fallout. The average lifespan of the survivors would also decrease due to hightened cancer-rates, but it would not be at a world-ending scale, more than enough for people to have one or two generations of kids before catching something deadly.
Economies would tank as most of the advanced manufacturing would be wiped out, but it's not a back to the stone age level, at worst we would probably go back to the late 1800s in terms of technology as whilst the more modern stuff would still exist, the knowhow to produce it along with the production chains would be wiped.
Society would probably survive, but nations that didn't catch too many nukes could potentially try to go and conquer other nations that just lost all their ability to fight, so I'd expect the borders to shift by a lot.
>tldridfk I'm just speculating, but it wouldn't be as bad as movies and media has been portraying it for the last 70 years.
