About a norwegian membership in EU I can say it won't happen anytime soon. The polls sway back and forth and the margins are small but when the question is actuallised it ends up on the "No" every time! It's just not likely as long as EU needs us or our resources more than we need them. The idea of being independend is very strong in Norway after being part of a union with Denmark for some hundred years and a forced member of Sweden for a short while. Besides, as long as there is a scarcity of fish and oil Norway can afford to stay outside. Funny thing is that when the fish farming industry is hit repeatedly by importrestrictions it still manages to get around it. A recent trend is to buy up scottish and chilean salmon farms. Even stranger is that when you buy "Scottish Smoked Salmon" you are more or less buying a norwegian farmed salmon smoked in Scotland.
Personaly I couldn't care less as I'm both for and against membership. As long as we can afford to stay out of it I'm happy.
