He has been really gentle with it. I think his intention was to do the rational thing and partition the country leaving leaving Kiev in the West to themselves but forcing them to restart the water supplies to Crimea and swear neutrality.I still say Putin has been pulling punches. He underestimated Ukraine and thought it could be taken with the scrubs.
But, he got WEFed. Zelenaky is willing to irrationally sacrifice everything.
At this point Vlad should flatten Kiev before they get all the new toys, especially anti aircraft and jets from the west knowing that leaving anything in the west means it'll become a heavily armed hostile state.
If he's gonna get charged with "war crimes" for Azov blowing up their own civilians he might as well do the war crimes and wrap this up.
