I'm not so convinced you can even talk about a "transition". Fascism and its nazi derivation, brewed and rised within democratic countries. And, lo and behold, they are still among us in our democracies so much so that they are ruling a number of countries.
Fascist Spain is Spain. Fascist Italy is Italy. Fascist Japan is Japan and Nazi Germany is as clearly just Germany.
Denying that is dangerous and doesn't give you the tools, as a country, to change.
