Yes, but there really were a lot of Nazis in Argentina.
There was a scheme whereby corrupt Nazis allowed Jews to be ransomed out of the death camps. Much of that money was shipped to Argentina as a hedge against losing the war, along with other loot.
Much of the Gehlen organization and their families also went to or through Argentina, which is the source of the slander against the Catholic Church vis a vis the Nazis.
My understanding is Skorzeny spent time in Argentina and helped other Nazis get there.
