I don't disagree with the analysis, but we were told initially that Ukraine was a Nazi state (despite Zelensky being of the Jewish faith), so it seems incredible that were that the case any remnant of the Ukrainian state would be allowed to remain standing. I'm afraid Putin and Lavrov have very little credibility in my eyes now, and should similarly be treated as the war criminals Bush and Blair undoubtedly are.
The Ukrainian state that will be left standing will be de-nazified and demilitarised. The nazi language policies etc will be consigned to the dustbin. Putin and Lavrov probably won't lose too much sleep over their credibility in the eyes of indoctrinated westerners. In world wide terms it isn't the Russian leadership whose credibility is shot. The ridiculous notion that being Jewish prevents you from holding Nazi supremacist beliefs is false.
Your comparison of Putin/Lavrov to Bush/Blair is also false but you are at least getting on the right track. Bush/Blair and every US president since and UK PM since their Iraq crimes are also war criminals and have carried on with the same orders. Obama, Trump, Biden, Cameron, Johnson and on and on.
Putin, Xi and Lavrov and co are the antidote to the western criminal governments. It is impossible to honestly compare the actions of Russian leadership with those of the US/UK. Their running dogs in the EU/NATO also warrant a dishonourable mention.
