There aren't really any Nazis anymore, aside from scattered groups of neonazi hate groups, which got me thinking. After the defeat of the Nazis in WW2, why did the Nazi party and Nazi ideology as a whole disappear?
I was thinking of this in context of recent radical groups in the middle east such as ISIS. The goal of defeating groups like this is to also defeat their entire ideology so that a new group doesn't just spring up when one is defeated.
So how was it done that Germany managed to rid itself of the whole notion of Nazism and become productive members of the global community once again?
The SINUS study on right-wing extremism, performed in 1980 in Germany, suggested that 13% of the population still had a "closed extreme right-wing mindset". This mindset was defined as a composite of authoritarianism, nationalism, xenophobia, chauvinism, antisemitism and pro-nazism. The study was repeated again in 2002, and had mitigated, but similar findings.
Thus, I deem your question rather suggestive, as the passing on of Nazi ideas within the German population is traceable till today. The ideas were not eradicated. However, the Nazi cult and its structures actually dissappeared, due to legal prohibition.
