Well.. i think denmark got included when souther sweden was a part of denmark...
But in that case Poland, The Baltics countries, nothern germany and large parts of russia would also be included, as SWEDEN pwnd them
Actualy, many ppl in Finland speaks swedish still...
And Norway, Denmark and Sweden had a union, basicly becoming one nation not THAT long ago...
So.. The nordic countries have ALOT of history... wars and unions.. but Sweden defently ended all this BS with slamming up a nuclear powerplant 30 km from the danish capital

MUHAHAHA!
They have whined over it for 30 yrs now... gotta be proude of beeing swedish..
Funny fact: Sweden actualy VOTED in the 50's regarding developing nuclear weapons.. and i assume you can guess the outcome.. (god damn pacifists)
