I haven't looked into Dugin's philosophy or ideology, but did hear him express his opinion about Putin on several occasions. If you know Russian, you can listen to
this video, for example. But there are others. He is a regular guest on this channel. Just search for his surname.
What I was able to understand is that he is a provoslavic patriot. That he is from a heavily patriotic branch, while Putin is actually a "centrist". So according to Dugin, even if Putin did an incredible job and literally saved Russia from destruction, he views Putin's actions as "half cooked".
He said that Putin's actions for the past 20 years is like being gifted with a very high quality and very beautiful shoe. But only one shoe. And what is missing is another shoe like this. And that until now patriots like Dugin are still waiting for the other shoe.
He does acknowledge that Putin constantly has to deal with various factions and that he does his best to protect Russia, but he also makes sure to mention that Putin didn't come from "them", the patriotic faction, but from the liberal one. According to Dugin, swifter and harsher measures should be taken in order to propel Russia toward it's rightful place. And instead Putin continues to keep or tolerate various liberal politicians that have clear ties to the West.
My personal opinion after listening to hs words, that despite his high intellect and proper ideas, he appears to lack adequate understanding of pathology. Especially pathology in power and how incredibly deep and vast it is. I can't say for sure, because I haven't looked into his writings, but this is what is possible to see from what he says.
What gives weight to this hypothesis is what Dugin said himself. According to him, despite his criticism of Putin's "half cooked" actions, he himself doesn't know how to solve the problem of the "deep liberal swamp". He doesn't have any idea how to take Russia to the next level in the factual manner. He obviously can provide an ideological background, but someone else would have to implement it.
Taking all of this into account, in my opinion Putin and his "half cooked actions" is probably the best what we can get. Because he does appear to have a plan and also a deep understanding of the forces he has to deal with. And he does it carefully and gradually. fwiw.
