Why if Sweden is 100% Nazi, never dare to join forces with Germany but help Hitler with iron ore?

sweden and switzerland were both Neutral in WWII

Switzerland had nothing of real value to the Germans and it would have been very difficult to overrun due to mountainous terrain

no real need to do so as they were entirely surrounded

Germany used Swedish Iron ore for steel throughout the war

they had easy access without having to invade Sweden because they controlled the norwegian port the iron ore was exported through , Narvik ,in the winter months

in summer the iron ore was exported via the baltic which germany also controlled

Sweden was 100% Capitalist in WWII, under the protection of "Neutrality".

Because Sweden wasn't 100% Nazi.

I love simple "If/Then" statements that you can prove false by proving the "If" part false.

Sweden was not and is not Nazi. Your question is based on an erroneous assumption and is invalid.
