See the books: “Ministry of Illusion”, by Eric Rentschler. And, “Projections of War”, by Thomas Doherty.
As for the rise of the Third Reich, see: “The Rise and Fall of the Third Reich”, by William Shirer, and “The Politics of Cultural Despair”, by Fritz Stern.
The leadership of Ukraine is not Nazi and is not totalitarian. The leadership of Russia is.
I consider your position to be deluded.
EDIT: A thorough rading of Hannah Arendt, such as, “The Origins of Totalitarianism” is in order too.
