Unlike the de-Nazification done in Western States of Germany by America, England and France, the Russians did a poor job of de-Nazification in the eastern States of Germany.
I actualy met (in a bar) an old German deportee from WWII. He was born in Detroit (from immigrant German parents) and was in his teens when he was deported. His story was an interesting one. He was a member of the American Nazi party. Got deported before the War started. In Germany once the war started he said he was "drafted" into the SS. (This is HIS story now, so consider we bought him schnaps to tell it). He said toward the end of the war his squad captured a couple of downed American pilots. He said his SS seargent wanted to shoot them. He said he and his buddy talked the seargent out of the idea, and suggested they could get better treatment when surrendering by turning them in. (I know, but that's the story). So the Americans welcome them surrenduring with two pilot prisoners. He get's offered a job cleaning up German minefields. He survives that and when the war is over he is allowed to enlist in the U.S. Army. He serves in Korea as a demolition engineer. He retires from U.S. Army with his full citizenship back! He drinks schnapps in a bar in San Francisco, that has a large U.S. Naval Aviator following. Great selection of German songs on a CD jukebox. End of Story.
