Huh, why? Even a full-scale nuclear exchange would have little effect on most food production in the US, which seems like it’s the only actual critical part. There are some countries that would be having serious issues here, but for the US, most sufficient food supply chains really aren’t that long, and you already by-default have on the order of 6 months to a year of local stockpiles (and this is one of the things you could easily increase to 2-3 years at relatively little cost). It would be actively surprising to me if food supply chains don’t recover within 2-3 years.

I take it you think nuclear winter is unlikely?
Also, how are you going to get the phosphate fertilizer to grow crops after a nuclear war?
