When did the Neo Nazi regime start?

In a way, Neo-Natzism began immediately after the demise of Hitler's army in World War II; however, as a true and open movement, it began at different times in different countries. In Eastern Europe, Neo-Natzis began making headlines in 2003-4. In postwar Germany, the movement came out of the underground during the 1960's. In the US, the prevalence in overt Neo-Nazism came to its fruition during the 1980s.
