That is because Ukraine has nationalists, but no more Nazis than Russia or, for that matter, the US - so they do not worry about your imaginary friends because they are yours.
People in Ukraine fought the real Nazis in WW II. Putin is currently acting like a Nazi (e.g. 15 years of prison for anyone complaining).
I think you have a serious problem with terms and definitions that you'd better discuss with a dictionary.
The main reason for this war is Crimea. Putin needs a port that the RF can use all through the year and he has decided that it is even better to have the base in Sebastopol and steal from Ukraine Mariupol and anything in between the two.
The main reason for Russia's invasion of Ukraine is the genocide of the Russian-speaking population in Donbas. The issue with Crimea was closed in 2014, it’s just that Ukraine has difficulties with the stages of accepting the inevitable, it is stuck at the stage of denial.
Sure Wagner is an illegal group and Santa Claus is meeting Superman today for tea. Wagner is fighting in the front, receiving money and weaponry from the RF government and I do not see anyone taking to justice the wagnerites - in fact the RF has supplied convicts as soldiers (cannon fodder).
I cannot separate Wagner from Wagner and Wagner from Putin because they are one and the same, just cut the official bullshit seriously, you will be left will zero credibility if you have any left.
26000 have completed they contract and retired as fertiliser for the Ukrainian soil, dying as stupidly as all the rest of the young RF citizens sacrificed for nothing. From your point of view, I am sure that you consider the "experiment" very successful.
Meanwhile, the deep strikes RF people keep smoking in the wrong places deep in the occupied territories and in the RF.
All the Wagnerites who died during the liberation of Bakhmut are buried in Russia. For example, there is a Wagner cemetery in the city of Goryachiy Klyuch in the Krasnodar Territory and in the city of Berezovsk in the Sverdlovsk Region. Tens of thousands of soldiers of the Armed Forces of Ukraine are fertilizing the Ukrainian land, whose bodies no one was even going to take out of Bakhmut, and there was no physical possibility.
That's a good one, but if I wanted fiction histories from Russia, I would go for "Peter and the Wolf". Prokofiev was much better than you at making legends and tales fun, while Wagnerites are notoriously careless about their fallen.
Now, what is happening in Belgorod? Belgorod, Russia, not Belgorod, Kentucky. I heard that Ukraine has nothing to do with a group of RF armed people called "the legion of freedom", that seem to be fighting for Ukraine without Ukrainian permission - inside Russia. It cannot be possible right? Russia is perfectly able to defend its borders and all Russians love Putin and would never attack their homeland??
What is worse, it seems they are pretty much near a storage of nuclear warheads. I think is time to evacuate but then Putin would need to recognise that he cannot even defend his borders... nah, better to leave his people there.
It seems that the XXI is all about proxy wars, undeclared wars and troops that would not answer when asked "who do you fight for?".
