Even in post-war West Germany, "denazification", e.g. excluding ex-nazis from roles in the new German society, was a failed policy that got discontinued after a few years.
For all it's flaws, it was far more successful than reconstruction.
Germany as a whole hates Nazis, both because they were absolute monsters in human skin, and because they brought unprecedented and absolute ruin and devastation to the country.
Any right-thinking southerner should feel the same way about the Confederacy. And yet, a good chunk of them actively think that those animals were some kind of national heroes, unafraid of proudly broadcasting their affiliation with them.
For all the apologists white-washing history, you don't see a lot of elementary schools named after Heinrich Himmler in Berlin.
The world might not have a lot of heroes, but it has no shortage of utterly irredeemable villains.
It got sabotaged by the ex-Nazi West Germans, who realized they could use West German re-armament and NATO membership (which was needed against the Soviets) as leverage to pressure the Allies to drop denazification and look the other way at them pushing the "Myth of the Clean Wehrmacht."
