Sweden during WWII

Well, Sweden wasn't a full collaborator. In fact, Sweden was a key player in helping Jews escape from the Nazis, using its neutrality as a shield to ensure Jews and anti-fascists could escape (almost all of Denmark's Jewish population and a large number of Norwegian Jews managed to escape to Sweden before the Nazis could send them to concentration camps). A number of Swedish diplomats also used their position to rescue thousands of Jews in Nazi-occupied countries, as well as using their positions to send information back to Sweden which "somehow" made its way into the hands of the Allies and the Resistance movements.
So, while Sweden was pretty much coerced into helping Nazi Germany, Sweden still did everything it could to undermine the Nazis.
