Would help to arrange an immediate CEASE FIRE.
Ukraine keeps the land that it presently holds.
Russia keeps the Crimea.
Otherwise:
a) Russia maintains Kherson territory east of the Dnieper River
b) the remaining, presently contested Ukrainian terrority along the border with Russia, that Ukraine has not able to hold, becomes a DE-MILITARIZED ZONE where the Ukraine citizenry can return to, for agricultural activity and support
c) a “shortest route possible land bridge” strip thru Kherson, thence directly to Russia, agreed upon by Ukraine and Russia, connects Crimea and Russia
d) administration and governance of the UKRAINE DE-MILITARIZED ZONE becomes the work of both Ukraine and Russia as neighbors, helping each other to learn how to get along
e) Ukraine does not join NATO
f) Russia withdraws from Georgia and from all land that Russia seized from Georgia, since the Russian invasion of 2008.
There is not a Ukrainian citizen who would agree to those terms, and if one did, they would be shot, hung, blown up.
The Ukraine Presidential Administration run by Andre Yermark would agree in an instant to those terms to please his bosses in Moscow, but knows he’d be dead the next minute.
