I doubt anyone would really like to waste a nuke on Serbia. Even if there was someone that demented, I think I'd be pretty safe.
Belgrade is 350km away, and there really is nothing of interest around here, aside from agriculture and socks factory...so, I'm pretty much safe from direct hit (though not the fallout).
Main problem would be that my town would very soon fall apart, in every way.
Infra-structurally, we already have some major problems, and lots of buildings would deteriorate and fall apart short time after the holocaust.
Economically, we are trying to get back up on our feet (before communism came, my town was one of the most advanced centers of textile industry in Europe - often compared with Manchester, believe it or not). Today, it's the different story, and we mainly rely on agriculture. Nuclear war would certainly put a stop in our tracks there, so there would be mass conflicts for food (as anywhere else in the world).
Socially speaking, my town is pretty peaceful as it is right now, mainly because of its size and population, which is around 80,000 and another 20,000 living in the country, though that would rapidly change as soon as the great inflation would begin.
Conflicts among many sub-cultural groups would become a standard, fights based on racial issues, and of course, looting, pillaging and everything that follows.
However, one thing would be missing - guns. Not that there aren't any arms around here, but physical confrontations, such as brawls, knife fights and such would be a lot more common.
Gang wars from one side of the street to another using Uzis? Not so much.
All in all, a standard scenario for most cities, only without a direct hit.
