Agree to the above, however this was - not only due to the Soviet Union having invaded Poland as much as Germany, but never declared war to by the british - a bit (!) hypocritical.
A lot of greater Nazis went to South Americaafter the war, actively helped by the "Kameradenwerk" and the american O.S.S. (the later CIA), or remained unaccused in high positions in Germany, to further serve "the West" against communism.
Not mentioning the scientists serving in the USSR and the US after the war, in the US the hunt for "Nazi" scientists was called "Operation paperclip".
They even continued german programs of testing vaccines against Malaria on american prisoners, with thousands dieing

Old joke: A peasant draws small fruits out of the soil, when a US sergeant asks him what he's doing.
The peasant answers "De-nazification ! I pull out the small ones, so the already big ones get fatter."
