The USSR would evacuate its cities right before the attack. The officers who drafted this war plan would have estimated a large probability that NATO would attack the USSR with nukes -- probably thousands of nukes. Then after waiting for the fallout to subside (e.g., waiting 3 weeks) the people leave their fallout shelters in the countryside and start rebuilding the cities. (Locations a few miles in diameter that were attacked by ground bursts will probably be permanently uninhabitable. Some of these locations would probably have been near city centers, namely, where US war planners believe the USSR's telecommunications nexuses were. Runways usable by Soviet stragic bombers would also be attacked with ground bursts, but of course none of these would be particularly close to city centers.)

Contrary to what many many chatterers on the internet say, "nuked to oblivion" is not a thing. A nuclear strikes with many thousands of strategic nuclear weapons against a country as large as the US, Russia or China temporarily degrades the country's economic and military capacity, then it bounces back. It is difficult to predict how quickly it bounces back, but it will not take multiple decades.

I never claimed it is realistic for the US to hold Chinese ports in 2025. The expert I heard talk about it was talking many years ago -- 15 or 20 years ago. I figure that if it was true of China 15 or 20 years ago, it is true of Russia today.
