Okay, so I'm writing a story about a character in one of the rebuilt cities of the world about 2000 years after a mass nuclear war that took place around maybe 100 years from now, a war that destroyed almost all cities with the first blasts, and the rest were destroyed in the firestorms.
I'm wondering, how different would these rebuilt societies be compared to societies nowadays, and, in what way will the nuclear war have affected the earth as a whole, like with nuclear winter and all that, would there still be much smoke?
How would a group of maybe 1000 or so people be able to survive a mass war of that type for so long?
I'm trying to make all of this as realistic as possible~ So this story isn't directly post-apocalyptic, but it's more about a story in a rebuilt city 2000 or so years after the war. Any help or criticism or anything would be greatly appreciated.
