your post is predicated on the view that it is just a conflict between positions of 2 countries, like say where to put the border. While theoretically "conflict of positions" description is true, the situation here is really different. The position of Ukraine which is its existence and existence of its people is in conflict with the Russian position of "non-existence of Ukraine and Ukrainians" (a bit more on that
https://news.ycombinator.com/item?id=30540609 ). In such situations there is no midway "half-existence". The peace agreement possible here is only like the one in 1945 with Nuremberg 2 for Putin and his clique. As Zelensky has said 20 minutes ago on Ukranian TV "Russians need to start learning the words 'reparations' and 'contributions'".
Lets give it a crack:
1. Immediate ceasefire and withdrawal of Russian forces
2. Russia acknowledges criminal nature of the aggression and gives up the war criminals - Putin, his generals, top political leaders and oligarchs who approved and participated.
3. Russia compensates all the damage to Ukraine.
4. Russia returns Crimea and Donbass (with grace period for the people to relocate who want to stay in Russia and/or Ukraine agrees for Russian language to be a second official language there and some extended autonomy for those regions, may be gradually expiring in say 50-100 years, may be some UN force presence for the next 10-20 years)
5. Russia gives up nuclear weapons and agrees to the limits on military power so it would be suitable and sufficient only for pure defense.
6. Probably some changes to Russian Constitution like hard term limit for President, electability of regional powers, freedom of speech, judicial independence and other measures to make sure that a fascist regime like the current Putin's regime has no chances to arise again.
