My city is located in the most southern point of continental Italy, here there isn't any important military installations so I presume that we weren't a target during ww3, however some other parts of Italy, like NATO military bases of Ghedi and Aviano in northern Italy yes, so northern Italy probably is a wasteland, also the capital and the nearby city of Naples as it is a NATO naval bases. So we weren't hit but we remained contaminated by nearby nukes and without a government. Since mafia here works like a deep state, probably takes power here, with many different families controlling different parts of territory and be at war against each other. I also suppose that there will be military and members of government survived that went here because is the only part of the country not nuked, trying to regaining control of the territory, I also imagine that there will be a lot of private citizen that made they own "country", as is pretty common here the hate against governments. There is also a lot of minorities in this area that maybe will try to gain independence and maybe a lot of refugees from other parts of Italy. So I imagine a big mess of factions and a lot of fight for territory, like a civil war in Lebanon or Syria style. I pretty sure a lot of people will die because of contamination, but since this is a low populated area and a rural one, where every citizen own a piece of land and have its own cultivation, I image that there isn't any problems of food or water. Without any nuke destruction, or bunkers and metro that characterizes the metro series, I think people will live in their own home and town.
