Since the end of the Cold War, the North Atlantic Treaty Organization (NATO) has experienced a profound transformation, evolving from a traditional collective defense pact into a dynamic global security actor. This study investigates the strategic reorientation of NATO, with a particular emphasis on the pivotal role of the United States in directing its post-Cold War agenda. The objectives of the study is to examine the extent and implications of U.S. influence on NATO’s evolving missions, strategic doctrines, and out-of-area interventions. Using a qualitative methodology grounded in historical analysis and policy review, the study adopts a dual-theoretical lens—Neorealism and Liberal Institutionalism. The study concludes that NATO’s continued relevance hinges on recalibrating its strategic objectives to reflect multipolar realities. It recommends a more balanced decision-making framework, enhanced burden-sharing among member states, and a reaffirmation of its foundational principles to sustain legitimacy in an increasingly complex international system
