Stepan Bandera isn't active today, he was a Nazi collaborating fascist that the nationalists in Ukraine that make up the majority of the current political climate generally uphold as good. This leads me to believe that you aren't really familiar at all with Ukraine's history, at which point you're better off not trying to get it drip fed from me, but instead read up on it and then come to your own analysis before engaging online.

That being said, because you did directly ask, there have been many far-right celebrations of Bandera and have been happening for decades. I even deliberately avoided Israeli sources, because the Zionists in control of Israel often label pro-Palestinian protestors as anti-semetic, but the Ukrainian neo-nazis are the real deal.

The article also mentions that in 2014, Azov was incorporated into its armed forces in an official capacity. This wasn't a brigade that became Neo-Nazi later, it was added after. The government deliberately and knowingly incorporated them.

I really do recommend you do your own research on this, though, as it's clear that you don't have a firm grasp of Ukraine's history, or what has gradually led up to the Russo-Ukrainian war.
