@flippac @profdc9 You seem to be confusing the situation in ~1933 (when everyone was trying to get people out of Germany by whatever means they could, and scientists had more resources than most people to do so) with the situation in ~1946 (when the USA and USSR were fighting each other over the spoils of victory)
