The dynamic nature of the international order and distribution of power has transformed the international environment into an arena of rapid political, military, and security developments. The establishment of NATO was also the result of one of these developments, including rapid expansion of Soviet's military and geopolitical power. The organization has faced many challenges throughout its life, one of the most important of which was the collapse of the Soviet Union and the disappearance of its founding philosophy. But in the post-Cold War era of international relations, NATO not only sustained its life by relying on its strategic concepts, using Russia's in its domestic power transition, as well as highlighting emerging threats such as terrorism, but also increased its members from 16 countries -before the collapse of the Soviet Union- to 30 countries in 2020. Despite NATO's high level of adaptation to international developments, the global distribution of power is changing rapidly, posing fundamental challenges to the organization. The present study seeks to address three key issues, including the challenges and threats facing NATO in assessing the international political and security environment, NATO's strategy for dealing with these threats, and finally its consequences. Using a descriptive-analytical method, while extracting the system of threats facing NATO, this article deals with some of the most important pillars of NATO's strategy for implementation until 2030. Finally, the global implications of NATO's new strategy are analyzed as well.
