>Wars don’t end by one party saying they are wrong and turning back. The only way for it to end is through negotiated settlement.

Negotiation is ongoing. That's what wars are, negotiation. It's up to Ukraine and Russia to decide when the cost is too high, and there's absolutely nothing wrong for Ukrainian allies to make sure that cost is tilted as heavily against Russia as possible.

Russia already committed genocide against Ukraine once (Holodomor). Russia (at least Putin) already announced the intention to erase Ukrainian identity (also a genocide). So let me ask you this, how high a price would you pay to not get killed or enslaved? Or would you want someone on your side to make sure the cost to enslave you is high enough for those wishing to enslave you that they go home?

That's ultimately what this war is about, Ukrainian wishing not to be enslaved, and their allies supporting that wish. And every negotiated settlement will have to include Russia no longer have a chance to enslave Ukrainians.
