Can’t be sure they are wrong but putins flirtations with war were mostly focused on limited war. My guess is the same holds true here and he will declare victory when the ukraine army in the donbas surrenders plus some opportunistic gains elsewhere as the fortunes of the conflict allow.
His peace terms i expect will be very imposing. Perhaps full ukraine air overflight. Or concession of some important road junctures. Or dismissal of small, all of the the ukraine gov cabinet. What is your estimate of this ? If you agree with the above, do you think zelensky would acquiesce to this ?
If I were to guess, reversing the effects of the US-supported coup of 2014 will be one of the first things on the agenda. A defensible border will be the second goal. Mountain ranges and big bodies of water often make good borders. In Ukraine, the Dnipro river looks like a good candidate for a Ukraine-Russia border.
