I'm all for this idea too if England is invited to be a member.
From my time in Scandinavia I think they are a people we would easily get along with, much more easily than the Scots or Welsh. The values and belief seem to be the same. Also, there are no sponging states in such a union like there are in the European Union.

Check it out:
GDP Per Capita ($):
2 Norway 41,941
5 Iceland 35,686
6 Denmark 34,718
14 Finland 30,818
16 United Kingdom 30,309 (would be higher as England)
19 Sweden 29,537

Total GDP nominal ($):
4 United Kingdom 2,295,039 (would be lower as England)
19 Sweden 383,816
24 Norway 285,604
27 Denmark 265,934
31 Finland 204,385
86 Iceland 15,388

TOTAL: 3,450,166 - far greater than Germany.

I may be anti-EU but I am pro NU (Nordic Union).
