That is the only way to stop it, kill & destroy until they have had enough. I often wonder where people get the idea wars have rules? Z boy is their leader, he could have stopped this long, long ago, his leadership is his country's & peoples path. All the blood & destruction is on his hands after any point, he rejected peace. If his people what to follow his ass off the cliff that's on them, as they could smoke his ass,... and stop it all at any time.
The ultra-nationalists in Ukraine who have previously openly threatened Zelensky's life for talking about potential peace would never allow it.
