For a while it was a brutal, communist, authoritarian, and imperialistic. After the end of the USSR it dropped the communism - which was mostly just a pretext anyway - but kept the rest.

It's essentially a medieval monarchy, with oligarchs as courtiers/barons and Putin as would-be emperor, with the difference that the excuse for military adventures is racist and homophobic psychological projection - terror of passivity, enfeeblement, and forced domination - and not religious nonsense about god being onside.

As is normal for fascism, the racism, mysticism and death worship are tinged with a miasma of nostalgia in a way that doesn't quite fit with the medieval world view.
