I'm trying to imagine a scenario where Norway would be in a seven-ish-front war, but the only scenarios I can imagine are:

Scenario 1: Norway becomes a socialist state, and so we basically just get Operation Urgent Fury 2, and there's not much more to say about it.

Scenario 2: There is an absolutely bizarre situation involving a three-way dispute of Orkney going hot, a fascist Sweden going irredentist, and a fascist Finland trying to establish a Turanist Co-Prosperity Sphere, and then other countries join in a "Scramble for Norway" in a "first as tragedy, then as farce" sort of way, using justifications like "peacekeeping" or "protecting their citizens abroad" or whatever else — the imperial core essentially cannibalizing itself as the periphery successfully resists the core's parasitism.

Scenario 3: The Second World War ended with the Nazis somehow negotiating with the Western powers to remain in power in Germany, Denmark, and Norway as a bulwark against the spread of communism. Nazi rule would inevitably collapse in Germany and Denmark at most a few decades later, leaving Norway as basically the German Nazis' Taiwan. When the "Greater German Reich" then inevitably goes rogue again, we basically just see a tragedy-then-farce sorta-repeat of WWII as it actually happened, except this time Berlin is substituted for Nordstern City.

Edit: Well, really, nothing says Norway couldn't become a bizarrely expansionist rogue state without being a rump of Nazi Germany. I feel like this wouldn't be any more farfetched than imagining this happening to Sweden and Finland.
