It makes perfect sense to me that if you're a European conservative in the vain of those trying to bring back Otto Von Bismarck style traditionalist authoritarian glory that you'd support Russia achieving ultranationalist goals under a certain banner held up by Putin.
I'd refer to something like: https://en.wikipedia.org/wiki/Ultranationalism#Background_concepts_and_broader_context
What is Putin trying to achieve? The advancement of the Russian race. The purity and cleansing of the Russian race. The destiny of the Russian race as a classification of people given its inherent strength and ability due to their higher intelligence, stouter courage, tougher determination, better physical endurance, and the like is to achieve a massive Empire across both Europe and Asia as respective of the God-given destiny given to this tribe with such excellent literature, artwork, music, and the like. The rejection of corruptive elements such as Judaism, homosexuality, feminism, transsexuality, pornography, Islam, and the like that pervert a white Christian people from its destiny is logical.
As conservatives in Vichy France put it, **Travail, famille, patrie** Work, family, homeland. As conservatives in the Kaiserreich put it, **blood and soil**. That's the mindset.
If you're, say, a European conservative looking to create what you think is the idea theocratic ethnostate existence for the native Ayran race in Europe, why not look to Putin? Why not see him as hero? He's upholding Bismarck's legacy.
To me, I should say, this is genocidal madness of the worst kind. Yet I admit that extreme national pride is a powerful thing. It's like a spiritual form of heroin addiction, I suppose. Terrible yet agonizingly appealing in the pleasure you feel.
