The central question investigated is how the United States can effectively utilize its unprecedented economic, cultural, and military dominance to address complex global challenges that require international cooperation. Joseph S. Nye Jr., a distinguished scholar and former government official, utilizes his extensive background in international relations theory to analyze the limitations of unilateral power. He argues that the modern landscape of global threats—ranging from terrorism to environmental degradation—necessitates a shift toward a more cooperative engagement strategy. By examining the nature of power in the 21st century, Nye provides a framework for understanding why traditional military might is insufficient for solving contemporary transnational issues.
