Sweden won't have time for war as they're spending all of their time to solve the king's sex club scandal
Let's see..
Terrain
Norway has mountains, infantry assaults sure would be bloody due attrition and swedish supply lines could have problems
Sweden, as far as I know, is pretty much like Finland, not very special problems
Resources
Norway has oil which is probably the most important thing to carry in war, fish industry and probably some mines. I don't know about financial status of neither
Sweden has Iron and probably other mines as well, wood perhaps..
Army & Navy
Norway? Army? Do they have? I have a feeling they'd be in problems all-around..
Sweden has quite a submarine forces and they'd probably cause problems to oil production, Both nations have some sort of air- and infantry forces but someone who knows better shall answer to this
Diplomacy
With no doubt USA comes and does same as in Iraq, plays the world police and ends up rebuilding both nations after they've tested a couple of tactical nukes there..
Result
Call this a draw.. Ah wait, JanH is coming, write there Norway won.. FAST before he notices!
