My suggestions:
armistice
plebiscites for all disputed areas
(voting boundaries in Russian-held areas to be set by Ukraine)
(voting boundaries in Ukrainian-held areas to be set by Russia)
all boundary points of an area not of a front line to be at least two kilometers apart
all areas to end at a front line
front lines to be those of the ISW as of an agreed date (or those of say 14/06/2024) except in cases justly deemed by the UN General Assembly to be off by more than a kilometer
no foreign troops in what is left of Ukraine
no ex-foreign troops in what is left of Ukraine
no Ukrainian membership in NATO
Ukrainian missile warheads limited to 50kg. maximum
Ukrainian missiles limited to 50km. range maximum
Why no limits on Russian missile payloads or ranges?
Who was it who started lobbing missiles at another sovereign state in this conflict, anyway?
