It should be noted, once the soviets got the technical skills they needed from the nazi scientists, they were deported back to Germany. Some were fined/deported for being irresponsible with rocket fuel.
Unlike Operation Paperclip where they were given citizenship and put in charge of scientific programs and prisons in America.
Or Operation Bloodstone, where the CIA put nazi war criminals in charge of South American special police forces to do more warcrimes under the guise of anti-communism.
