The problem is that an end of the war means thousands of unemployed men with actual war experience running around in Russia. If Putin can not show what he gained in the last two years, during which a lot of those men lost their friends and maybe family, those men might get some ideas. Wagner marched on Moscow after all.
So Putin just gambles that the West gives up on Ukraine. That is the only way he can actually show something.
Doubt the Israel plan. Syria and Sudan are pretty good places to show morality is relative. At least with some propaganda.
