Thanks for the detailed analysis, RN7. You nailed it, IMO. An additional area of strategic economic interest, as far as Sweden is concerned, is the oil shale deposits in Estonia.
I took the time to check out the T2K Scandinavia Sourcebook and its depiction of Sweden, IMO, is pretty nonsensical. It describes Sweden as the most devastated of the Scandinavian countries. Not only are they badly nuked, there's a bloody civil war. It doesn't seem congruent with established canon, or historical reality. I much prefer the vision that RN7 outlined (as it aligns very well with my own).
Which sourcebook is that Raellus? The only one I know that references Scandinavia are Boomer, with some information also in the Survivors Guide to the UK and NATO Combat Vehicle Handbook.
