Bolshevism really did make all of Europe fracture along strange lines.
Finland's membership in the Axis was purely military. So far as I know, there was no totalitarian ideology or anti-Semitism in WWII Finland at all. Finland merely joined in when Germany attacked Russia because it remembered the "Winter War." It's really too bad the Allies didn't declare war on Stalin from the time he invaded eastern Poland. Finland was the only sympathetic Axis partner.
The Iron Cross, originally, had no anti-Semitic connotations whatsoever, being a Prussian military medal created during the Napoleonic wars. Lots of German Jews won Iron Crosses during World War I. Unfortunately, like the Confederate Battle Flag, anti-Semites have hijacked it.
