This war will indeed end in negotiations. Neither side is capable of dictating peace on the steps of the other's capitol. To date, Putin has been unwilling to even enter into a ceasefire unless NATO and Ukraine recognize Russia's annexation of Donetsk, Luhansk, Zaporizhzhia and Kherson. Russia does not even hold the capitals of Kherson and Zaporizhzhia, and does not have complete control of any of the four. That would not be entering negotiations, that would be forcing a Ukrainian surrender. They have fought the Russian army to a standstill and the correlation of forces, particularly with the arrival of modern combat aircraft and renewed US aid is again swinging Ukraine's way. Putin's only realistic hope for a victory is that a Trump administration will force a negotiated solution in Russia's favor.
I think there are few other factors worth mentioning.
On the beginning of this war I mentioned that this will turn in a war of will of the two nations and cause humanitarian disaster.
And it looks like resources are running short. (probably on both sides, but not with the same dynamics)
One is political.
Presidential term of president Zelensky has expired. While this can keep ongoing for sometime in Ukraine, In Russia (some kind of) election has been done, Putin term is just fresh.
In WW2, both UK and USA had elections before the end of war. Same thing during Croatian war of independence. (it is not impossible)
So, delaying elections on account of war, can not drag for too long, and keep credibility.
Any election held in Ukraine in this situation can be difficult, if administration changes, as with administration change policy towards the war can change as well. (from uncompromising fight till kick the Russians out - to - negotiate with some territorial trade acceptance) .
Actually we dont know what eventual present opposition would say, and where do they stand now.
(Nobody is thinking about Ukrainian political opposition at this moment)
Thus I found DW article quoted above, interesting, in overall media control in Ukraine.
Just as it was interesting when general zaluzhny gave interview in the economist, which some time later resulted in his releif from position, when he strayed away from official govt policy (strategy?).
Next is economy.
Russia is facing serious problems, but still functioning.
Ukraine: When watching last congressional debate in US, when republicans temporary blocked aid to Ukraine, it came to my attention, that US Govt, pays for Ukranian administration and public service costs.
To me this means, Ukrainian economy and infrastructure is in ruins.
While this system of financing can go on for some time, it is not sustainable for long term.
On the battle front, not much progress either side, mostly frozen lines.
I dont see planned strategy or winning tactics on either side, my guess is Russians see time is on their side, and just keep the pressure. War of will, or war of attrition. Which on the end will depend on the will of Ukrainian people to fight or negotiate, and the poll results show by now some willingness for negotiations, and in this situation most likely negotiations will be with territorial trade. (more and more I see there North and South Korea situation).
Providing of course, that Nato does not engage directly.
