My read on the situation is that Zelensky is willing to make any deal for lasting peace. Meaning, if a deal is made and Russia ignores the ceasefire or continues its invasion in a month or year, what will happen to them? This is literally what he asked because Russia has violated all of the previous agreements in the same way.

What Trump was offering was to take a chunk of their resources for another temporary peace offer. Which as noted above, will almost certainly be violated in the near term by Russia again. So Ukraine is not only back where they started, but also lost a chunk of their resources. Why would Zelensky agree to that?
