Neo-nazis are a curse that is all over the world in many countries. In fact, I challenge Russia to invade the US to get rid of ours. Hell, by their logic, they should be invading much the world. Even themselves?
Now, back to relevancy with additional information: The Azov Brigade in Ukraine did have a high concentration of far right-wing and neo-nazis. (They utilize symbols that are associated with the German SS; some are no longer used but you will still see them from time to time) However, they have been a pain in the ass for Russia since the Donbass conflicts started which is nice. As part of a deal with Ukraine, the Azovs ultimately down-sized and began to reject much of the extremest ideology to become a more formalized political group in Ukraine. That didn’t stop Russia from spreading more propaganda though. Russia needed to degrade support for the Azov group because they were quite effective in battle and needed to fight them in any way possible. (More info: en.m.wikipedia.org/wiki/Azov_Brigade)
Quick note: Russia still spreads fake videos of the Azov Brigade in formation giving Nazi salutes and such. I am not saying that doesn’t happen still, but most of the videos you find “proving” Ukraine is still Nazi are fake. Nazis are still going to Nazi, unfortunately.
