After the end of the Cold War, NATO's strategies for various issues have experienced many changes based on the dynamic nature of the structure and global distribution of power, as well as the rapid political, military and security developments in the international environment. In this regard, we have seen that during the past decade, when relations between Moscow and Kyiv have entered a phase of conflict and tension, NATO as a Western military institution has played a more significant role in this. In fact, we should note that the crisis in Ukraine has caused widespread fear among Western players that the Russian Federation may once again become a big and interfering power in the international arena. In this regard, and in order to manage Moscow's power and prevent the maximization of the increasing power of this Eastern European power, many Western countries have tried to prevent Moscow from achieving its pre-designed goals through NATO. Influenced by the mentioned concept, the author of the present work has tried to answer the questions of why NATO became an active actor in the Ukraine crisis after the February ۲۰۲۲ crisis with a descriptive-analytical approach and using the conceptual framework related to NATO's strategic culture. has it been the hypothesis raised in front of the mentioned question is that due to Ukraine's strategic position in the conflict and competition of NATO members with the Russian Federation, NATO has become an active player in the Ukraine crisis through intelligence, military and diplomatic support from Kiev.
