Now it is difficult time for negotiations due to Russia being in a favourable position and being able to demand more. While Trump needs to fulfill his promise to "end the war in the first day", Russia doesn't have to hurry although it wants to end the war too (after all, it was supposed to last just several weeks).
A good time for negotiations was in 2022, but it is lost.
> I doubt any peace negotiated will last decades
I think Russia doesn't want the second war like this because it was supposed to last several weeks but ended up lasting several years.
