Um Im not sure about this but the EU collapsed and they nuked each other I think

I think the people who are willing to do anything to survive. Would survive.... Really the worse threat to us humans would be other humans. I think the people that survive in the Prison system have a really good chance at survival. They know how to quickly defend themselves and how to quickly make deadly weapons. They also know how to manipulate people through psychology and force.

Some guy might not know if that plant by the river is safe to eat, but he can force some other person to eat it for him.

you know whats funny ive never had internet till last year cuz i used to live in middle of no wear and all i did was hunt and play with guns and knifes all day lol but then i ran away so now i live in a town with kids who no nothing of hunting and stuff and its quit annoying and funny kinda lol but now i have internet to which also keeps me slackin in shooting lol computer is a great way to get nothing done ohh and also i did have ps1 ps2 and ps3 but used it in a rundown place in the middle of no wear lol moral of story is i guess people that dont live how i ussed to like hunting for survival are gonna have a hard time adapting not saying im any better than annone or haveing a better chance im just really good at hunting and shooting lol

I reckon really depressed people with nothing left to lose would survive the post-apocalyptic wasteland because they wouldnt care that the world as we know it was gone

Hmm, high ranking politicians and their families, the super rich dynastic families and lots of military types, kind of like a proto enclave.

I would think that libertarian survivalists would do very well; they tend to be very paranoid, and stock up on food and ammo pretty consistently, always prepared for the worst. I also think that conservatives from more rural areas would do very well, as they tend to have very tight-knit communities, are more charitable/religious, and many of them have served in the military. Soldiers at military bases would likely be best off, unless of course they were a target of the attack.

Doomsday theorists that actually built underground fallout facilities.

Vault Dwellers are real!

Exactly! Who do you think all those psychotic raiders are decended from?

Anyone not in a secret goverment agency can survive in FO.

Seriously though, the lucky, the fortunate, the smart, and the strong.
Raiders ( gangs ) would not last that long as they tend to fall on themselves when things get tough.
I would say small defensible towns who have access to food and medicine, while being far enough away from major settlements.
But only as long as food and habitants last, once they are gone it would be a slow decline untill you get places like FO3, without the canibals.
