Nazis in Argentina

Latin Americanist here.

Short answer, Argentina culturally gravitated towards Europe since the 19th century, like most Latin American countries who viewed European culture as superior and modernized. Argentina also shares a long immigration history with Europe and "whitened" its population by encouraging Germans, Italians and basically anyone from Europe who could take over indigenous territories. In most ways, Germany was the model for economic, political, and cultural modernity. Argentina shared many economic ties with Germany, and England, like beef and grain. Even Argentine uniforms were modeled off Bavarian military-style and looked almost identical to the Nazis. During the war, Argentina remained neutral throughout, joining the Grand Alliance literally days before the war ended. Of course, many Nazis used Argentina and other Latin American countries as places of refuge, and some war criminals escaped justice the help of European institutions like the Vatican and the Red Cross who facilitated their travel to Argentina, among other places.

It became the main aim of German foreign trade policy to re-orientate German trade to Europe [...especially SE Europe...] and those parts of the World not subject to colonial preference agreements, in particular South America^1

My italics. Essentially, in order to sustain the accelerated programme of German re-armament, German Public Works and German autarky the NS Government traded with countries that would offer the best return on exports, and Argentina was one such country. This economic alliance undoubtedly assisted Nazi fugitives in finding a post-war haven there.
