Demilitarisation is an absolute non-starter, I don't see how any sovereign nation could ever agree to that. I assume Russia are putting it on the table so it can be traded away for something else. If what you say is true about Ukraine being willing to trade away Crimea and the eastern territories, then I don't think an agreement is necessarily that far away. Your initial demands in a negotiation are rarely your red lines. The most contentious point (again, assuming you are correct that Ukraine is willing to cede the above-mentioned territories) will be bloc membership. Zelensky could possibly give some informal guarantee that he has no interest in NATO membership, but having your own foreign policy is a fundamental part of being a sovereign state, so being coerced into promising they will never join this or that bloc is kind of incompatible with Ukrainian statehood. And down the line they will definitely be eyeing EU membership. Personally I would be sad to see territory ceded to Russia as it would reward their brutal and criminal tactics. I am also highly sceptical of Russia's willingness to abide by its obligations under any peace agreement. However, I appreciate that for Ukrainians especially, ending the bloodshed is the most important thing.
