Can 2025 be the last year of the war? 

How realistic is that?

It is realistic, but only in regard to Ukraine. The global confrontation will continue in any case and is likely to intensify. The contradictions remain unresolved, and there is no reason to believe that positions on a global settlement will even come closer in the near future.

However, Ukraine is already practically destroyed. Its agony may last for some time, but survival is no longer possible—unless someone decides to fully support it, which is unrealistic since it would be too costly and pointless.

Kiev, having exhausted its ability to fight, is not surrendering solely because it hopes for a new escalation in relations between Russia and the West. However, the West appears most likely inclined to abandon Ukraine under conditions favorable to itself and then find a cheaper and more effective platform for continuing the confrontation.
