I hope the Norwegians are paying attention to who is living within their borders. A nation of 5.5 million people with 1.5 million foreigners living there. Pretty soon there won't be much Norwegian culture left after it get diluted via diversity.
I'm not sure why western Europe tried the melting pot approach like America. Those places each had a unique culture. Spain is very different from France which is very different from Italy. America has always been a hodge podge of people. I suspect that why America is more violent than most of western Europe. Diversity breeds strife and social unrest.
