A Nordic Sourcebook?
Wow! If someone would put out a version translated into English they would instantly become a T2K legend.
I like the idea of Soviet attacks on NATO installations in Greenland as one of the prime motivators for Denmark throwing her support fully behind NATO. At first, it would be sub-launched Spetznaz raiders. This would provoke the Danes to agree to increase their support for NATO's operations in Germany/Poland. The Spetznaz raids would fail and so, eventually, a sub-launched nuke would finish off the NATO installations on the island.
As for evactuating the inhabitants to Denmark, that's going to be very tricky. Ships would be vulnerable to Soviet commerce raiders. Aircraft would be slightly less vulnerable since I don't think Soviet fighters would be able to operate along likely flightpaths between Greenland and Denmark. Trouble would be finding enough aircraft and fuel for them to do the job, post TDM.
