It is acceptable for the US - they can keep NATO together exploiting 'Russian threat' narratives, and sell its energy to the EU and take Russian share in it.
It is not acceptable for the USA, because every day on the current level of conflict means additional risks for American population. And they won't keep NATO members together because, say, Estonia clearly understand that the local Russians can declare Narva's People Republic in any moment and America won't be able to make a shit about it.
It is acceptable for Zelensky - (well, will be) because he won't have any choice. He most certainly will lose the power and the flow of money for personal gains, so he does everything to prolong this war, but the times are changing it seems.
No. Its not acceptable for Zelenskiy because as soon as the war is eneded - he is dead. Therefore, you can't freeze the war without killing him.
It is acceptable for the Putin regime - because 'the golden elite' of various ranks can turn back to a such desirable and not-too-distant-ago usual life with boutiques and holidays and assets in the 'declining' West.
No. Putin's regime is more about earning money, not wasting them. Life of oligarchs is not "all boutiques and holidays". Its a hard work. And, talking about boutiques and holidays, China or Maldives are not worse that Europe. What is even more important, Russian Federation is about safety of Russian people. And the safety of Russian people is unachievable without elimination of Banderlog terrorists. Therefore, Russia will continue elimination of Banderlogs - in Ukraine, in Britain, in Canada, in Argentina and anywhere else.
It is acceptable for 'poor Tarasiki' - who will get 'a bad peace' but peace anyway, with Russian money (300 bln of greenbacks, remember?) being used for rebuilding and social sphere. (No worries, Yurez, it is just numbers on a monitor).
Poor Tarasiki are poor, first of all because they are stupid. Nobody will give you Russian money. Neither Russia, nor the EU, nor the USA. Poor Tarasiki will pay the debts, and the most smart of them will flee from Ukraine as soon as the borders are open.
For whom it is unacceptable - it is for stupid Vankas who suddenly will realize what they had fought for was a scorched land with evaporated towns and villages that would have to be rebuilt by their cost. But that is okay, Vankas can took part in that constructin process personally to reduce the costs needed.
Russia is a democracy (in its normal meaning). That's why Vankas will fight until decisive and profitable victory. Putin knows it, and that's why in his New Year adress he declared 2025 as "The Year of Motherland's defender". Which obviously means that Russia is starting preparations for a war, not for a ceasefire. The first song in the New Year (at the official New Year concert) was "All we need, is the victory. One for all of us, and we don't care about the price".
