It is very easy to end the conflict, it is just that the only realistic scenario for ending the conflict does not suit either Kyiv or Washington.
I think you're wrong, Putin's death suits Kyiv just fine. Not sure about Washington, he's been dead for a while so probably has no strong opinions about this.
If Stalin were alive in Ukraine, he'd be happy with Putin's death, too. Of course, maybe Zelensky is the new Stalin. But, he has a long way to go to catch up to Stalin's murders.
