Abstract

mations of the international system since the mid-twentieth century, particularly following World War II, throughout the Cold War, and into the post-unipolar era. The research focuses on the intellectual and theoretical foundations of American global hegemony and the political, military, economic, and cultural mechanisms through which Washington consolidated its leadership role. It also highlights the impact of major geopolitical shifts—such as the rise of competing powers like China and Russia, and the emergence of cross-border challenges, including environmental, health, and digital crises—on the effectiveness of U.S. grand strategy. Adopting a historical, analytical, and structural approach, the study provides an integrated reading of the trajectory of U.S. grand strategy, bridging its philosophical roots with its practical applications, while offering a foresight perspective on the future of American leadership in a multipolar international order. The findings conclude that while the United States still retains significant adaptive capacity, this adaptability is increasingly contingent upon its ability to embed smart power instruments into a more flexible vision that accommodates technological, demographic, and geopolitical transformations shaping the contemporary world.
