The article carries out a scientific and practical analysis of the terms used by the legislator in the disposition of Article 436-2 of the Criminal Code of Ukraine, and which, in fact, are an innovation in the science of criminal law of Ukraine. In particular, the author's interpretation of such forms of the objective side of the above-mentioned criminal offense as "justification", "recognition as legitimate", "denial", "glorification" is given. In addition, the authors carried out: substantiation from the point of view of domestic legislation and international law of the facts of the armed aggression of the russian federation against Ukraine, which began in 2014, and the temporary occupation of part of the territory of Ukraine; understanding the general reasons for the criminalization of actions that form the objective side of the criminal offense provided for in Art. 436-2 of the Criminal Code of Ukraine; consideration of the above terms in their general meaning and in the meaning determined by the context of criminal liability.
 The non-acceptance of the obvious fact that the military-political leadership of the russian federation launched an aggressive war against our country and occupied part of the territories, when this fact was established and recognized at the state level and by the international community, in the conditions of martial law, is, on the one hand, a prerequisite for collaborative activities within the state, and on the other hand, to the support of the crime of aggression by representatives of other states. Justification, recognition as legitimate, denial of the armed aggression of the russian federation against Ukraine, glorification of its participants are part of the information war of the russian federation against Ukraine, aimed at leveling the external grounds for repelling the armed aggression of the terrorist country, as well as preventing society from rallying around a national strategy of unity to repel threats to the national statehood, territorial integrity and inviolability of Ukraine.
 Despite the fact that since the introduction of criminal liability for the above-mentioned acts, enough time has passed for the formation of judicial and investigative practice of bringing people to criminal liability, the theoretical basis for the interpretation of certain terms has not yet been created. In general, the scientific conclusions obtained in the article can be the beginning of the formation of such a foundation.
