Putin has always been a dictator, but he hasn’t always been a fascist. He started his career as a moderate technocrat that happened to have incredible access to KGB resources. Very handy if you’re in the market to be forever president. As time went on he’s been mixing and remixing his stances and aims.

As far as NK, I’m not sure they’ve ever been fascist. They’re just a vanilla authoritarian police state.

A major component you can use to point out fascism specifically out of the rogues gallery of evil ideologies is the notion that a fascist government specifically derives its power from endlessly designating and promising to destroy out-groups. If it lasts long enough to run out of targets, it goes on to consume itself.
