Quite a few Nazi's were found in Argentina were they not? Surely if Hitler was there they would have given that information up.
Allegedly... A few U-Boats went 'Missing' just before the end of the War, as did a lot of Nazi Gold and Art Treasures and a few high ranking Nazis, two U-Boats are known to have landed in Argentina U-977 and U-530, I think the whereabouts of the other missing Subs are not known although one was reported to have been scuttled off Patagonia and various other sightings by Allied ships reported in the South Atlantic. So, do you think the South Americans were interested in helping the Nazis, or just wanted the Gold?
I really like the Admiral Byrne 'Operation High-jump' stories though, how the U-Boats went to the South Pole with Nazi UFOs and built a new World deep underground, it's a damned good read and would make a brilliant Hollywood movie as it's completely Bat-**** Crazy!
