Germany made being a Nazi illegal and everyone is fine with it.

Denazification was something of a joke.

West German President Walter Scheel and Chancellor Kurt Georg Kiesinger were both former members of the Nazi Party. In 1950, a major controversy broke out when it emerged that Konrad Adenauer's State Secretary Hans Globke had played a major role in drafting antisemitic Nuremberg Race Laws in Nazi Germany.

Between Operation Paperclip, the incorporation of the CIA, and the Cold War formation of NATO, Nazis were rapidly reformed and reintroduced to the public sphere over the next decade.

Operation GLADIO in Europe transformed a bunch of the Italy / Greek / Belgium / France WW2-era fascists into cartel bosses and arms dealers spread all across the continent. Fascist ideology, in the wake of WW2, was returned to its original Communist roots and was justified as a means of compelling Europeans to stay true to their nationalist roots and not fall victim to the Soviet Internationalism sweeping through the Middle East, Latin America, and Africa.
