The Soviets also took maximum benefits from the scientists they brought back. An interesting thing is that the Nazi scientists worked for about a decade in the USSR to develop V1 and its improved versions, however, they were allowed to communicate directly only with the young engineers. They could never meet the senior board of engineers who were controlling the projects, giving instructions and making decisions ... all being behind the scene! ... The James Harford's book on S. P. Korolev (the anonymous chief designer of the USSR space program) gave me a lot of insights about this.
