What would the effect have been on the war had Germany invaded Sweden as part of the operation that took Denmark and Norway in June 1940. This would have robbed the Allies of a base for underground resistance operations and would have given the Nazis a center for recruitment of racially acceptable men into the SS and regular army as well as greater economic potential. The downside is the additional cost of occupation and the initial thrust to fight their way into the country, assuming a strong Norway-like resistance takes place. Perhaps a negotiated surrender can take place and save lives on both sides, since Sweden is part of the Aryan volk?
