>He means like letting their troops cross sweden, sell iron to them, ask them to specially mark the documents of jews. Perhaps he's seen the photos that nazi and swedish soldiers were taking together at the time, on the border with occupied norway.

Sweden was officially neutral, so the Germans were permitted to buy iron in return mostly for coal, which we needed not to die during winter.

Once Germany had occupied Norway they argued that it was permitted to transit troops. Some transits were indeed permitted, but at the same time Sweden accepted many Norwegians in and many of them were trained militarily to later retake Norway.

With regard to the marked passports, that is not in any way support for the Nazis. We wanted to be able to control our immigration and to know who was attempting to enter. Policy w.r.t. to Jewish immigration was also reversed as the attacks on Jews in Germany crossed the line.

>Or… hear me out… they're corrupt and got something from the owners of weapons factories?

We won't get more weapons factories because of NATO. Much of our weapons industry is successful because we've been one of the few highly industrialised third world countries.
