If you are telling me that Sweden (who has always been neutral) and Norway need protecting, tell me the last time they were invaded or threatened.
Well, since you asked, I believe it was in 1940. Germany invaded and conquered Norway in 2 months, despite a substantial Allied troop presence, and occupied the country for 5 years.
Although the Germans could have overrun Sweden with similar ease, there was no reason to. Sweden was of little strategic importance because Germany had them boxed in, and Sweden was more than happy to sell large quantities iron and iron ore to Germany on an exclusive basis, without which the Germans could not have carried on with its war effort. Sweden also allowed German troop and supply trains to run through Sweden. As the war drew to a conclusion and it became apparent to the Swedes that Germany was probably going to lose, the Allies nevertheless had to pay Sweden to stop selling iron ore to Germany.
