Every nuclear power since WWII has had the ability to invade many countries with minimal fear of retaliation.. Of course, lots of fingers point to the U.S., but China and Russia have invaded places as well. The article basically postulates that any state with nuclear weapons guarantees its basic territorial integrity. That means sure, we might have landed in Normandy and secured France and the USSR might've secured Poland, but the German heartland would've been a no-go for the Allies for fear of a nuke to Paris or London, and a safe-zone for Hitler and his agenda for Jews, etc.
