They also were complicit in running the German war machine’s wheels, the ball bearings industry in Schweinfurt. We lost a hundred planes in one raid on these Swedish enterprises.
Sweden didn’t have much of an army? Neither did the Poles, but that didn’t stop them from sending horse cavalry against the German supply trains in 1939.
The ballbearings Germany got from outside their country came from Switzerland (as did watch movement parts,etc - but the US also got them to counter what the Germans had).
Sweden provided some materials but I just don’t have the list in front of me.
