Watch Hunting Hitler...and maybe you will realise that is is highly probable he did goto Argentina.
At least thats what the CIA think anyway...but what would they know. :)
Its on record...that they actively hunted him 8 years after the war(All files become declassified after x amount of years.
They have intelligence stating there was high ranking nazis landing in Argentina on uboats.
I went to a place in Chile(cant remember the name but its on Hunting Hitler)
From the outside its like a concentration camp.
Nowadays...German people,German music through tannoys,German food,Typical German clothing being worn,huge watchtowers,barbed wire fencing....you would be convinced you were in Germany.
I never knew at the the time....but the place had been notorious for fleeing Nazis.
Many people went there...and simply disappeared.
