A lot of Nazi sympathizers in Sweden. And business was business. OTOH they did take in a lot of Jews…. As opposed to say, Switzerland. Which also did a heckuva lot of business with The Third Reich.
True,
Both the Swedes and Swiss benefitted and played both sides of the war.
Switzerland is also how most of your Nazis that were still alive at wars end and escaped went through.
From Switzerland they would get to South America.
Many of the guys we and the Russians went after were mid or even lower level since most the top level Nazis committed suicide by gun, cyanide, or the enemy (charge them with a gun), some we took over since they were valuable for us (scientists / engineers, Intel folks with contacts / knowledge of the East, example: Werner von Braun to whom we have monuments erected in Huntsville Al.). Finally some of the Nazis simply escaped to places like Argentina, Brazil and Chile. So we ended up crushing the nuts of a lot of folks that weren’t really that important or bad (Doenitz, Hess...), but someone had to pay.
