Indeed. The second to last one is pure pragmatism and would be the obvious choice every single time. It's a simple matter of value and viability. German culture, industry, science and technology are truly illustrious and the Allies scraped their initial ideas of turning it into a pastoral nation quickfast, lol. You see things like Operation Paperclip mentioned often, but this rarely gets attention.
Operation Osoaviakhim (Операция Осоавиахим) was a Soviet operation which took place on 22 October 1946, when NKVD and Soviet Army units removed more than 2,200 German engineers, scientists and technicians from the Soviet occupation zone of post-World War II Germany for employment in the Soviet Union. Much related equipment was also moved, the aim being to literally transplant research and production such as the relocated V-2 rocket center at Mittelwerk Nordhausen, from Germany to the Soviet Union, and collect as much material as possible such as from the Luftwaffe's central military aviation test center at Erprobungstelle Rechlin, taken by the Red Army on 2 May 1945.
The USSR's main Nazi man, a genius no doubt.
Helmut Gröttrup (12 February 1916 – 4 July 1981) was a German engineer, rocket scientist and inventor of the smart card. During World War II, he worked in the German V-2 rocket program under Wernher von Braun. From 1946 to 1953, he headed a group of 170 German scientists who were forced to work for the Soviet rocketry program under Sergei Korolev. After returning to West Germany in December 1953, he developed data processing systems and contributed to early commercial applications of computer science. In 1967, Gröttrup invented the basic principles of the smart card as a forgery-proof "key" for secure identification and access control.
