The concept of Germans escaping to Argentina is real, ranking party members and leaders would hide with the help of the Catholic church and make their way to neutral Spain, then take a boat to Argentina which accepted Germans and their ideals plus helped them attain new identities and jobs in the country. Mossad hunted down and assassinated many high ranking Nazis in Argentina and Spain. Operation Paperclip specifically only took German scientists, and the Russians did the same. If you could not be taken under Paperclip, you went to Argentina.
