This is pure wishfull thinking. It doesn't matter what you or I want or would like to happen, a country that is decisively winning a war wont just stop and go home before having secured a peace deal from the other side. This idea that Russia could simply leave is not realistic. Russia would suffer a net loss if they withdrew for no reason like this, and the Russian politicians obviously wont chose that when they already realized most of their military objectives. Ukraine on the other hand has litteraly no reason to keep fighting. It can't be overstated: they are losing. Dispite all of the military aid from the US and EU and all the economic sanctions on Russia, the frontline has bearly moved since the strikes on Kiev; even being so generous that you ignore the fact that Russia hasn't commited nearly has much to the war as Ukraine did proportionally, the situation could only be described at best as a standstill. Now, after almost two years of war, Russia has successfully wiggled out of western sanctions, now selling/buying to India and China most of what they used to sell/buy to Europe, Western aid to Ukraine have dwindled hard, with the US's contribution, Ukraine's biggest supplier until recently, being now a pitifull fraction of what it was in 2022. Not to mention that multiple western countries have admited that they ran out of things to send to Ukraine and are starting to shift their attention away from it anyway with the Israel stuation. With all of that and the failure of the 2023 counteroffencive Ukraine definitely lost any chance of winning the war.

At this point, all Ukraine is doing by continuing to send soldiers to the meatgrinder is increasing the deathtoll for nothing. The war will end with Russia taking The Donbass, Luhansk, and possibly the whole coast, regardless of how many zeros the Ukrainian deathtoll has. The only REALISTIC thing that can put an end to the war is a peace deal on Russia's terms. Now matter how much you say that "Russia could just stop", that's not happening.

It's also importent to be aware that there would never have been a war in the first place without western meddleing. As soon as the maidan coup happened the region was doomed for conflict, the west stirred up conflict on purpose with the hope of weakening Russia without them having to fight directly. Russia tried to propose deals with Ukraine that would only impose them to stay neutral and not get involved with NATO, Ukraine often showed iterest in signing, but every time, some western politician flew to where the talks were happening and for some reason Ukraine changed their mind just after. Pretending that only Russia is at fault is ignorant of the geopolitical situation in the region, as expected from westerners who probably didn't even know Ukraine existed before 2022.

So you're just going to ignore the fact that this all started as a simultaneous result of the Five-Eyed Empire blatantly flouting the Minsk Accords multiple times, and then couping the last Ukranian president to install a neonazi regime; all to the end of letting NATO encircle and exterminate Russia. You're literally worthless to discuss geopolitics with if you just approach from a settler's tabula rasa.
