A 'Treaty of Versailles' type solution is not a good idea for durable peace though, harsh reparations, despite any sense they might be 'fair', seldom lead to both countries returning to be prosperous democratic countries (and to be clear, neither is a capitulation by Ukraine - that would be seen by Putin as locking in its current gains, with no real incentive not to try again for more despite what the treaty might say).

The best outcome for everyone is if Russia ends up being a genuinely pluralistic democracy (i.e. anyone in Russia can have political views, and the public selects its leadership in free and fair elections). Then Ukraine can normalise relations with Russia, and Russia stops being a threat to democratic institutions across the world as a whole.

I think the best way of thinking about it is not that Ukraine has a Russia problem, but rather that Ukraine and Russia have an oligarch problem (with Putin chief amongst them). Therefore, in a fair world, the oligarchs, and not the Russian people, would pay. It is true that Russians (and indeed some Ukrainians in occupied regions) have been radicalised by the oligarchs, so some kind of deradicalisation would be needed even if the oligarchs disappeared.

Solutions that look to negotiate how to reduce corruption and authoritarianism in Russia from the top are therefore the most likely to succeed long term. Shorter term solutions could include a negotiated end to hostilities coupled with agreements for Ukraine to join a defensive alliance that the oligarchs wouldn't consider provoking - which could be followed up by a carrot approach to easing sanctions in exchange for progressive movements towards genuine Russian democracy. This might give oligarchs enough push to take off ramps to cash in what they have plundered already, and slowly be replaced by less corrupt alternatives going forward.

Recovery from oligarchy for Russia might also by costly for Russia though - essential assets plundered from the USSR are now in private hands through crony capitalism; the best solution would be for many of the major ones to go back to or be rebuilt under state ownership, under genuine democratic leadership. But that is likely easier said than done given the state of Russia.

And a 3rd party enforced DMZ on the border.

Okay then the war would go on and on until your government collapsed. A peace agreement is actually good here given that they just showed they were unable to reclaim much land with their counter offensive.

How? Ukraine's made like a few square kilometers of progress with hundreds of billions of dollars of funding while Russia has just fallen back from their low ground territorial gains to the more easily defensible high ground.

What leverage does Ukraine even have for those demands?

Russia can't be accepted back into the international community until Putin is in a jail cell or in the ground.

Slava Ukraini was literally the battle cry of the OUN, which collaborated in the holocaust. Find a different motto.

I'm kind of confused why Prigozhin did what he did, even. He knew Putin was going to try to kill him afterwards, I had assumed he had his own play but I guess not.

Hasn't he had pretty good relations with, like, literally all of BRICS?

If Putin wants to defuse tensions with NATO, he knows what to do.

I personally don't want anyone to die, but it's not like Ukraine asked Russia to invade them, steal their land and kill their people.
