France, with 31-6.

Oh, you didn't mean the rugby match but the war? Well, while the entire German army was engaged in a war on the eastern front, France / Britain occupied Germany in a textbook blitzkrieg. Dazed and confused, cut off from their occupied homeland, the German army goes 'uh, now what?' and decide to just run rampage in the Ukraine. They spend the rest of the year fighting a war of attrition on Soviet soil.

France and Britain spend the rest of 1941 in occupied Germany, waiting for the Germans and Russians to exhaust each other. By spring 1942, France / Britain attack from the west, America lands in Vladiwostok. Six weeks later, they meet at the Ural mountains. Having annihilated Nazi Germany and the Soviet Union, they now turn their attention towards Japan. In one swift overland campaign staged from occupied Russia, they drive them from mainland Asia. Under threat of the huge allied force ready to stage an invasion from Korea, Japan surrenders. By the summer of 1942, WWII is over.
