Also “ethnocentric”. But as usual, we first need to have a shared definition of fascism. If we use Eco’s Ur-fascism, many aspects are there (the moral and cultural decadence of the West, which is both too strong and too weak)
For not being fascist, the propaganda and general 'optics' and messages coming out of Russia sure look a lot like Germany in the 1930s, and Ukraine is basically the same playbook as Sudetenland - both started with a claim that a suppressed German/Russian minority must be protected from atrocities by the Czechoslovakian/Ukrainian 'aggressors' by integrating those lands into the 'Reich'. Thankfully Putin is by far not as successful bringing a much smaller country to its knees than Hitler was.
the guiding intellectual stream of the Russian government is Dugan, as best exemplified in Foundations of Geopolitics.
Dugan is unambiguously hard right and has intellectual ties to other openly fascist types. His ideology is explicitly ethno-centric and has a strong resemblance to classical Fascism (in the Ur-Fascism sense), and a looser one to German-style National-Socialist thought, esp. as it relates to Russian ethnic domination of Europe
I agree with the general sentiment though!
