I said they should withdraw both politically and militarily. What that would look like is up to whatever agreement could be reached in peace talks. On the other points you're simply being blind to history, read about peace negotiations and you'll find that the parties involved extend far beyond just the combatants especially in conflicts adjacent to super-powers.

How do you want to achieve that? What path do you see for such a solution?

What you are suggesting ist just not realistic in any way. It’s pure fantasy.
