When the WW2 began on September 1, 1939,the fate of Sweden was unclear. Sweden managed to maintain its official neutrality throughout the war. It also allowed the allies to use Swedish air bases between 1944 and 1945.
Sweden wasn’t persecuted,they were just attacked by the Germans and their allies because Sweden was free and peaceful during the WW2.Sweden was neutralized because war was taking place.
Sweden was a nice country they were peaceful and people from other countries can come to Sweden to forget the WW2.
