I am currently playing Germany in the year 1940, I am running a deficit of iron ore due to my growing IC and no country is willing to trade any. I am considering invading Sweden from Norway to obtain more however I am unsure which is the best plan of action, should I invade sweden and release them as puppet Scandinavia? Or is it worthwhile keeping sweden under German rule to make the most of the iron ore? Should I lay a claim to the region rich in ore and then release them as puppet? Interested to know what you all do In your games.
