This data highlights the longevity of the conflict and its impact on Ukraine's territorial integrity.
The increase in the level of occupation in Donetsk and Luhansk regions indicates the persistence of aggression from Russia. Meanwhile, the static nature of frontline positions in 2025 suggests a possible stabilization of the conflict, although this does not reduce the threat to Ukraine's territorial integrity and its population.
