I think it’s a fair point to say it was considered as a serious threat to certain countries(US/Russia/UK/China etc). And militaries certainly did prepare for it. But other than Switzerland with all their bunkers - which society in all facets prepared for it, really?

WW2 with it’s restrictions & rationing, and almost all civilian economy/effort being redirected to the military is I think what a lot of people are wanting in my honest opinion.
