Norway instead of Torch

What if the Allies invaded Norway rather than North Africa?

It would be difficult, but could draw German troops, threaten Swedish supply routes, and alter the Battle of the Atlantic.

The answer stresses that a Norwegian front would be difficult to supply and fight over. Even a stalemate could force Germany to retain or divert major forces that would otherwise serve on the Eastern Front. Allied bases in Norway could threaten Swedish ore routes, bring British night bombers and American day bombers closer to Germany, and contest Baltic movement. Control of the Norwegian coast could also make it harder for U-boats to enter the North Atlantic, giving the campaign consequences well beyond Scandinavia.
