The Real Odessa: Smuggling the Nazis to Perón's Argentina, originally published in London in 2002 and since then translated into Spanish, Italian, Slovenian, Portuguese and German, has had wide repercussions in those countries through which Nazi criminals and their collaborators passed in their escape, especially in Italy, the Netherlands and Argentina.[4] Following publication of the book in Italy, a group of parliamentarians in Rome demanded that Prime Minister Berlusconi open an investigation into the passage of Nazis through their country.

In Milan, SS criminal Erich Priebke, sentenced to life imprisonment for his part in the Ardeatine Caves Massacre of 1944, sought a court injunction against the Italian translation of Goñi's book, demanding 50,000 euros in damages. He was turned down on both counts, although he had already won a series of judicial cases against media stories about him.

In Genoa, archbishop Tarcisio Bertone distributed 50,000 copies of a "Special Edition" of "Settimanale Cattolico" ("Catholic Weekly") announcing the creation of a special commission of inquiry to investigate Goñi's revelations regarding the role of the Genoese curia in aiding the flight of Nazi war criminals through the port city. In the Netherlands, KLM opened an internal investigation following the book's unearthing of documents regarding the use of the airline by Nazi officers after the war.

In Argentina, President Néstor Kirchner ordered the repeal of a secret directive of 1938 prohibiting Argentine diplomats from granting visas to Jews fleeing from the Holocaust in Europe. This was the first official admission by the Argentine government of the anti-Semitism that marked the country's immigration policies during and after World War II. Goñi's book also caused previously secret files relating to the entry of Croatian and other war criminals to Argentina to be released.
