The reality is that both sides are laying out unrealistic terms for surrender right now.... and that's fine. The start of a negotiation is always to start with a stated position and go from there. This war will end at the negotiation table... at least we hope it does becuase unconditional surrender won't come from Russia, but it could come from Ukraine.
The real question is have both sides suffered enough for a negotiated end to this war? Look, it sucks, but that's the truth of it. It would be good to see an end to the fighting and dying in Ukraine. Wars suck. The only side winning in this war is the US. They/we spend a pittance of money and watch Russia burn their future generation, military reputation, and global standing to the ground. That's the #2 political opponent the US has in the world, and it's acting as a great example for to show China (the #1) why it should behave itself over Taiwan. Win win!
But wars suck. It's easy to sit on the sidelines, but there a lots of people fighting and dying over there who have nothing to do with make the decisions for war. Yes Putin's demands are ridiculous, but so are Ukraine's. That's fine. Put them in a room and hopefully they can figure out way to end the killing that's in between the two.
