Most of Northern and middle Germany was seen as a complete loss in any way.
There where hundreds of French tactic nuclear missiles pointed, not at Warsaw Pact countries, but at Germany, to bring the Soviet advance to a halt before it could reach the French border.
German Tornado fighter jets would have been outfitted with nuclear weapons to drop them - you probably guessed it - on German soil.
There would not have been an “after the war” for Germany.
Welcome to the insane logic of nuclear warfare!
