Long lost Nazi party membership booklets and propaganda material dating back to 1941 were found in crates.

Official story

On Aug. 8, 1941, customs officials and Foreign Ministry representatives randomly opened five [of 83] boxes [en route to Japan] and found postcards, photographs, and propaganda material from the Nazi regime.

A federal judge then ordered the entire shipment to be seized on Sept. 13, 1941, and three days later sent the case to the Supreme Court.

A month or two ago, President Milei said that stuff about Argentina's Nazi past would come out. I went "Mehhh....let's wait for it."

Earlier this year, the Argentinian government, under the Javier Milei administration, made available to all citizens a series of declassified documents that include information on Nazi operations in Argentina.
From 1933 to 1954...40,000 Jews entered Argentina as they fled Nazi persecution...

[but also] the post-war period saw a wave of high ranking Nazis fleeing Europe...

"[some,] like Adolf Eichmann or Klaus Barbie, were eventually caught by the Mossad or Nazi hunters,”...12,000 names of Nazis in Argentina...had Swiss bank accounts...at the Schweizerische Kreditanstalt, which became the Credit Suisse bank.”
