There are a number of big issues.
Donetsk: The wishes of the people in the part still held by Ukraine need to be made clear to the world. Ukraine’s need for its defense assets needs to be made clear to the world.
Security Guarantees to Ukraine: Putin doesn’t want foreign forces in Ukraine. The vast majority of Americans don’t want US troops to be placed at risk or to be drawn into a foreign war. Brits and the French probably feel much the same. What I see as possible is funding and tactical defensive weapons provision for Ukraine’s defense.
Place it under UN administration for one year (Russian troops can remain on the line of contact but Russian authorities are to have no role in administration). Allow the original inhabitants (and only the original inhabitants) to return. Restore normalcy to their lives. Hold a UN administered referendum after one year.

What I see is “ demilitarization “, after Vlad is awarded his ethnic Russian provinces. Lughansk ( already 100 percent liberated) and Donetsk a given ( Donetsk still has 25 percent more to go) and no NATO.
As for “ funding”, the Ukies have already wasted away $$$ billions of US taxpayers money….all flushed down the Ukie toilet. No more.
