Thanks for the response. As a hypothetical: If we could go back in time, was there ever a point you believe the world or specific nations should've reached out to Hitler to negotiate a ceasefire and to let him have whatever piece of land he gained at that point in time? What are the long-term consequences of permitting such blitzes for territorial control only to be slapped on the wrist and permitting said tyrant to remain in power?
The problem with peace is that it's not without precedent; and that precedent is to say, "the bully gets rewarded." Ultimately, isn't it the victim who has every right to decide how much they're willing to bleed to fight back against the bully? Hence why every voice from NATO has been, "it's up to Ukraine to decide for how long they wish to continue this war."
At this point I don't believe Ukraine is desperate enough to take that bargain. I think they know the wind is in their sails. I also think both sides are holding their breath and long-term decision-making based on the outcome of the US Presidential election. If things somehow went very south for Ukraine and they were at risk of losing significantly more territory (not a +1% gain) and Trump gets reelected and the alliance fragments, then perhaps they'd try to negotiate such a DMZ on the condition that they also get into NATO to ensure Russia will not re-arm and attack refreshed.
