Depends how you consider "quite well" - the total collapse of Russia's military credbility, the insanely high casualty rate, the loss of material, for something that they were already allowed to use in Crimea, and a part of the Donbas?
I wouldn't call that "well" at all. Seems like a completely disaster.
If you've already decided that any criminal cases against him are a "witch hunt" - then how could it ever be proven to you that he did something wrong?
