Churchill thought that "if we invade Norway and Sweden then we can stop those ore shipments."ORIGINAL: Zartacla
It's on both. Churchill thought "hey, if we invade Norway, we can stop those iron ore shipments. Let's invade!" Turns out he might have been wrong (although really all we can do is speculate). Germany thought "Hey, if they invade Norway, they're going to stop our iron ore shipments. We better invade first!" In WiF, the British player thinks "Hey, if I invade Norway, I might get lucky enough to stop the occasional iron ore shipment. Seems like a lot of risk for very little reward. I'll pass." and the German player thinks "Hey, if the CW invades Norway, it might cost me an occasional ore shipment, but I'll gain US entry benefits, free naval units, he'll lose some units, and I can still march into Oslo or defend Narvik. Don't let me get in your way, Churchill"
It is no speculation that Narvik was not needed to ship the ore to Germany. After the invasion almost no ore was shipped through Narvik and the ore shipments increased. It all went through Swedish ports. Narvik was to damaged after the fighting to ship the ore.
Edit: I hope that no offence was taken by my posts. It was not my intention.
