@Dylan:
Okay say the German defense in Norway did go to fight Russia or something, do you think the Allies might then attack Norway?
Unlikely imo, although if Germany left Norway totally empty, I think Norway would be secured by some british forces (along with our very few Norwegian soldiers), but if we look at the map, choosing Norway instead of France would mean that the allied forces had to be shipped onboard the ships again and then sail to Denmark, or Northern Germany, or France for an invasion.
Stalin said no foreign soldiers on Russian soil, so the hypothetical invasion force (for Norway) could not move from northern Norway to Northern Russia, south to balticum, and then to Germany. It was definitely most practical to invade France and then move east to Germany.
It would even be better to just send all allied troops to Italy and moving upwards towards Germany instead of invading Norway.
And the Germans treated us “fairly” good, taking the war situation into consideration, I think less than 3000 Norwegians were killed during the war, and that is not so bad if you look at some other countries which were not so lucky, so there was no immediate need to liberate Norway for the intention of saving our civilian population.
