Time has already run out. Russia will now accept nothing but unconditional surrender.
You may be right, assuming that Putin actually wants to be responsible for a broken and bankrupt Ukraine and the humanitarian crisis that will accompany a Russian takeover if Russia chooses to occupy Ukraine post war.
My definition of honorable settlement is Russia has some territorial rights to Eastern Ukraine and the rights of ethnic Russians are respected and guaranteed, Ukraine remains neutral and not part of NATO
An agreement along those lines may still be possible.
One thing for certain, Ukraine is not going to be any position to make demands on much of anything and Ukraine asking for war reparations. repatriation of Crimea and war crimes tribunals for Russian leadership is laughable at this point
