The problem is that, if the Russian people aren't pressurised internationally then they won't take down Putin and this business won't end satisfactorily for anyone if Putin isn't removed as leader of Russia. Let's say for example, that he completes his annihilation of the Ukrainian nation, how is he going to hide the truth of what has been done from the Russian people? He can't and so he will need to keep them scared of him and they will be heavily oppressed from now on. Under Putin how will Ukraine re-build itself after he has finished crushing it into the dust? It will take billions, there is no chance the west will pay for it if Ukraine settles with Russia and the Russians won't be able to after having spent a fortune on the munitions to do the damage. It's also unlikely that, even if Zelensky does a deal with Putin that the people of Ukraine will not accept it now and so there will be a continual war of attrition against the occupying Russian forces. In short the only endgame that stops the Russian people and the Ukrainians suffering a whole hell of a lot worse than they already are is if they themselves pull down Putin and all his lackeys. I read that the Turks are claiming that a deal between Russia and Ukraine is getting closer but, if you were a Ukrainian, would you trust Russia after what they have done?
Putin has made the biggest goddamn mess of this business and there isn't really any way that he can extricate himself. He wants glory but whatever happens now he will not achieve that so he will either be destroyed or he will become the most awful tyrant that Russia has ever known in a long line of tyrants.
Personally I would like to see the Russian nation smashed utterly to bits. They ain't much use to the world and they have been a royal pain in the ass for a hundred years.
Even in WWII they were not our allies, we simply had a common enemy and if Russia hadn't been turned on by Germany then Stalin would have enjoyed watching the West burn.
