What would the peace negotiation would be??
Talked about this a thousand times. Both side wants stuff that the other will not give.
I mean do you think Russia would accept Ukraine NATO membership. Or do Ukraine accept dropping NATO claim?
I don't see how each side dropping the term on their specific requirement for peace. Russia did not threaten Ukraine enough for Ukraine to stop fighting and accept Russian term, meanwhile Ukraine did not recover enough ground for Russia to just let go.
I mean, what can peace mean, if both sides are not going to settle with each other term?
You have to deal with reality, that is why.
Unless they can militarily defeat Russia, which they by fact of their size and military strength they can't. They are going to have to give up some of the historically Russian regions of the area in the first place
