The article deals with the problem of moral justification of humanitarian intervention by modern just war theorists. At the beginning of the article, we discuss the evolution of the dominant paradigms of the moral justification of war and explain why the theory and practice of humanitarian intervention appears only at the present stage of the development of ethics and the law of war. It is noted that theorization of humanitarian intervention began in the last decades of the 20thcentury. This is due to a significant transformation, a retreat in the legal and ethical studies of war from the position of radical condemnation of aggressive actions and the recognition of the political subjectivity of non-state groups. Thus, there is a rethinking of the long tradition, the Westphalian system of international relations, according to which the state was recognized as the main participant of big politics, and its sovereign right to conduct domestic policy was considered indisputable. Further, we take the works of Michael Walzer as the main source of modern conceptualization of the ethics of humanitarian interventionism, since Walzer repeatedly addressed this topic and formulated a position on this issue that is representative of the entire modern Just War Theory. The arguments of Walzer and his supporters in favor of the moral justification of humanitarian intervention are considered. Among them are the following. First, the argument about the state as an organization which goal is to protect the rights of its own citizens. If this goal is not not achieved, the state shall loose its power over these people and in this territory. Second, Walzer calls for identifying governments and armed forces involved in mass murders as criminal and, therefore, deserving of punishment. Finally, there is, perhaps the most important, demonstrative argument: an appeal to the self-evident impossibility to stand aside in cases of mass violence in any state. This is followed by a critique of these arguments, as well as a demonstration of how the modern Just War Theory can respond to these criticisms.

_A few public actions prepared the way for the Russian invasion of Ukraine, the purpose of which was to define a special military operation as forced, necessary and inevitable. The use of armed force against Ukraine was discussed during those public events. The Russian authorities applied many arguments, and a great deal of attention was paid to the moral justification of war. In this article, I consistently analyze three problems: why did Russian officials use moral language to justify the war, what arguments did they use, and would these arguments retain their effect in the long term. I will examine several addresses made by the President of Russia and the Russian Federation Security Council meeting materials to address these questions. I conclude that Putin's lack of legitimacy forced him to justify the war in moral terms, and the peculiarities of Russian moral discourse allowed him to do that. However, even if this strategy was effective to a certain extent at the beginning of the war, it can hardly be stable and sustainable._ _Keywords_: invasion of Ukraine, Russia, Ukraine, just war, morality.

The article considers the modern meaning of Kant’s doctrine of war. The author examines the context and content of the key provisions of Kant’s concept of perpetual peace. The author also reviews the ideological affinity between Kant and previous authors who proposed to build alliances of states as a means of preventing wars. It is noted that the French revolution and the wars caused by it, the peace treaty between France and Prussia served as the historical background for the conceptualization of Kant’s project. In the second half of the 20th century, there is a growing attention to Kant’s ethical and political philosophy. Theorists of a wide variety of political and ethical schools, pay attention to Kant’s legacy and relate their own concepts to it. Kant’s idea of war is reconsidered by Michael Doyle, Jürgen Habermas, Ulrich Beck, Mary Kaldor, Brian Orend. Thus, Doyle tracks democratic peace theory back to Kant’s idea of the spread of republicanism. According to democratic peace theory, liberal democracies do not solve conflict among themselves by non-military methods. Habermas, Beck, Kaldor appreciate Kant as a key proponent of cosmopolitanism. For them, Kant’s project is important due to notion of supranational forms of cooperation. They share an understanding that peace will be promoted by an allied authority, which will be “governing without government” and will take responsibility for the functioning of the principles of pacification of international relations. Orend’s proves that Kant should be considered as a proponent of the just war theory. In addition, Orend develops a new area in just war theory – the concept of ius post bellum – and justifies regime change as the goal of just war.
