The Allies had an amoral attitude towards Nazi scientists. They were an intellectual elite and were helped to leave Germany thereby by-passing the Nuremburg Trials. Many would have been convicted and, some, would have been sentenced to death. They had soft skills, which normal SS thugs didn’t have, and so interrogators could more readily accept their implausible ‘explanations’. They also had skills that were in demand. Wernher von Braun, the rocket scientist, is the most egregious example.
