The purpose of the research is to reveal the possibilities of inviting Ukraine to the North Atlantic Treaty Organization in the context of the escalation of Russian aggression. The research methodology is based on the principles of historicism, systematicity, scientificity, verification, authorial objectivity, moderate narrative constructivism, as well as the use of general scientific (analysis, synthesis, generalization) and special-historical (historical-genetic, historical-typological, historical-systemic ) methods. The scientific novelty is that for the first time in historiography, the current prospects of Ukraine's invitation to NATO have been considered. Conclusions. Accession to NATO is a constitutionally enshrined main priority of Ukraine, a fundamental condition for its survival. Today, the political elite of Ukraine and Western governments are unanimous on the issue of Ukraine's membership in NATO. The Russian-Ukrainian war acts as an arena in which the political and military strategies of the global West are formed and break into the intentions of those world forces that promote anti-democratic values and, using Western technologies, intend to play a leading role in world civilization. The further development of the world system depends on Ukraine for a long period, and possibly for centuries to come. The need to invite Ukraine to the North Atlantic Treaty Organization is due to the possibility of overcoming the global crisis of international security. In favor of the rapid Euro-Atlantic integration of Ukraine, the uniqueness of the military experience in the large-scale modern war against powerful Russia, the removal of the financial burden from the NATO members, the demonstration of the unity of the Alliance and the ability to respond to modern challenges testify. Ukraine demonstrates commitment to high spiritual values, such as freedom, independence, dignity and self-respect, on which the Alliance is built. Thanks to its armed forces and active civil society, it deserves NATO membership.
