The end of the cold war and the dissolution of the Soviet Union forced NATO, which was established to ensure the security of the member states, to take a collective stance against international threats, especially the Soviet threat, to be included in out-of-area operations. The international war on terrorism declared by the US, which is NATO's dominant force, following 9/11, has also contributed to NATO’s interest as a global border guard to shift from Europe to countries in the Middle East. At the summits held, NATO decided to update its strategic concept accordingly. The cooperation between the US and other members of the organization has been dramatically affected as a result of the shift to unipolar world order. Relations with allies have suffered from the peremptory stance and one-sided strategies adopted by the US since 9/11. Due to shifting security understanding, NATO has begun to push its partners to develop new security policies. In this study, by comparing the Cold War policy of the organization and the post-Cold War policies The transformation in the perception of security will be tried to be analyzed. In the changing dynamics of the post-Cold War world architecture, the measures taken by NATO to keep up with the “new world order” and their weight in world politics will be scrutinized.
