I think the reality is if a nation state wanted to they could shut down 80%+ of infrastructure (water, power, internet etc) and any domestic manufacturing by attacking something in the supply line. There's terrible security everywhere, you literally have ransom ware groups taking down key infrastructure on accident its so bad. Our insane military budget does nothing to prevent this and it honestly seems almost as bad to me as a few nukes could be.
