If Denmark was a mystery then certainly Norway should have been mentioned as well in this article. Northern Norway was liberated by the Soviets and to my knowledge no allied forces ever set their foot in Norway at the end of the war.

Thus in principle the Russians could have claimed all of Norway.

They did not which I think is one of the reasons we in Norway retained a pretty good relationship with the Soviet Union through the Cold War sometimes to anger and bitter resentment by our American NATO allies which seemed to prefer to refer to the Soviet Union as the “evil empire”.
