It systematises the cause-and-effect relationships of the problematic lacunas of the Russian-Ukrainian war. It highlights the substantive and criteria-based scaling of the Russian-Ukrainian war. The methodological significance of the phenomenology of wars for the objective handling of problematic gaps in the Russian-Ukrainian war is clarified. The influence of the context of the world order crisis on the specifics of the course of the Russian-Ukrainian war is outlined. The significance of the principle of realism as a criterion for victory in war is revealed. The significance of the idea of the European choice as an ideological tool for Ukraine`s confrontation with Russia is generalised. The specifics of information warfare as an essential component of classical warfare are analysed. The policy of ending the war is understood as an important area of interdisciplinary knowledge. The significance of a discursive environment, organised on the principles of deliberative democracy, for the needs of generating effective strategies and tactics for Ukraine`s confrontation with Russia is conceptualised. The target audience of this research is social and political scientists, teachers of higher education institutions, politicians, executives, and students.</jats:p>
