Germany and Poland aren't under existential threat from Russia. If your neighbor wants to invade you and has 3x the population, you can't pick and choose who you're going to let defend your country. Therefore the blame for tolerance of Azov is purely on Russian aggression.

Look at Mariupol right now. The only reason it's still standing is because of Azov. This shows that the tolerance of Azov was unfortunately necessary in order to stop Russian aggression. If you are upset by Azov, blame Russia.
