Amnesty International is an absolute dumpster fire of a source. I have personally seen their bias on display during my time in the Balkans. Not to mention they are riddled with FIEs.
Far right and Nazi are two words that do not belong in the same sentence. NAZI is actually an acronym. Nationalsozialistische Deutsche Arbeiterpartei to be exact. Translated to English it means National Socialist German Workers party. How many far right organizations have socialist anywhere in their name or party stance?
As far as the Azov battalion and other interesting Ukrainian entities, the term Ethnic Extremest Group (EEG) would be a bit more accurate, and play less into certain IO narratives. EEG was used to describe similar entities in the Balkans. Or EG would work as well. Them claiming to be Nazis is about as ridiculous as Frankie Faison's character in the 1996 film Mother Night claiming to be the "Black Führer of Harlem". After all didn't the actual Nazi's consider Russians and Ukrainians to be untermench?
Regardless of all that, this is a conflict we should not be supporting and a result of really, really, really bad decisions made by both the Ukrainians and our government in the 90s. And if Brandon, the EU, and NATO had done a better job this would not be happening.
