The Wikipedia page for "Ratlines" [1] discusses "systems of escape routes used by Nazis and their collaborators" and how they settled in Rome, Spain, Genoa, and various South American countries.

But there is no mention of Werner Von Braun there - for that you need to go to "List of Germans relocated to the US via Operation Paperclip" [2], which is described as a list of "German scientists, engineers, and technicians (...) taken from the former Nazi Germany to the U.S. for government employment".

So my answer would have been "everywhere", but apparently Nazis fled exclusively to South America while good, honest German citizens working for the official German party were taken to the US.
