It’s easier for a Communist country to flip and become a Fascist one instead of a Democracy. This is what I think has happened in China and Russia.
These days it seems as if 'Fascist' is simply used as an epithet. Russia is becoming (has become?) an authoritarian state w/the trappings of a democratic one. It is not (yet) a Fascist state. Nor is it clear to me why Putin wants to move in this direction, although he certainly has been doing so. Cui bono? I can't see it.
