Well interesting note, my grandfather was a staff officer for Gen. Eisenhower in WW2 at Supreme Allied HQ in London responsible for arms/ordinance planning and evacuations for Operation Overlord (D-Day). He had a self-deprecating sense of humor and evacuating Nazi scientists became "Operation Paperclip" (because they were literally paperclipping new identities to each scientist's file- someone's joke that he loved). He called the Berlin Airlift "Operation Vittles" (he grew up on a farm in Alabama and not too far from there they relocated Nazi scientists with their new identities to Birmingham Alabama, in fact the neighborhood became known as "Kraut Hill"). Eisenhower asked him to become the U.S. military attache' to Buenos Aires, Argentina for the very reason you mention above, because Argentina was a major destination of the Nazi officer rat lines out of Germany. He regretfully declined because my grandmother would never move that far away from her twin sister. However he later joined the Air Force and was a Lt. Col. at Holloman AFB in New Mexico while Eisenhower was President in the 1950's working on classified projects, which were heavily related to the work being done by the former Nazi scientists in Birmingham. They were designing missile systems for the Air Force (among other things! lol).
