If anything, the Banderite groups worship Wotan and his coterie in Valhalla. Other nationalist groups in Z's government are purely cynical in their use of "Christianity" (shutting down churches they don't like, expropriating monasteries, etc.)
The Teutonic Knights would be embarrassed of Z's inept conduct of this war.
Do you really believe that nonsense or did you find it on some Russian ultra-nationalist’s website?
