San Carlos de Bariloche was and continues to be a haven for Germans in Argentina. It is where the majority of the high-ranking Nazis went at the end of WWII to escape war trials. Many lived out their lives either here or close by in places like Mendoza (the regional wine capital) in Chile (especially in Patagonia) or Paraguay. What I find most interesting is the Americans, including several of the American Presidents who have made a point of buying property there (Like Ted Turner of CNN). The Obamas, the Clintons and it is my understanding that the Bushes as well would go there on vacation. Hummmm. What comes to mind is the book by Jim Marrs entitled The Fourth Reich.
