The Mossad Nazi hunting is mostly a myth. Israel actually didn’t do much. Eichmann was an exception.
On the contrary, the Israeli government hired dozens of Nazis war criminals. The Mossad hired a death squad commander who murdered 100,000 people.
Israel also rejected extradition offers by the United States for dozens of Nazi war criminals. The U.S. had denaturalized Nazi war criminals and wanted to deport them to Israel for trial.
Even after the Prime Minister told the Mossad to prioritize the abductions and extrajudicial executions of Nazi fugitives, they kept slacking.
