Globalization has resulted in a deeply interdependent international system. Strategists and policy makers must understand globalization and its effects on multiple aspects of social interaction in order to provide well informed national security policy recommendations. Of particular importance is globalized economics. A nation#65533;s economic strength is the foundation of its national power and lends credibility to the diplomatic, military and economic actions and policies a nation undertakes in the international environment. A nation#65533;s weakening economy will inevitably lead to a loss of national power and to a declining influence in the international system. Given the stagnant United States economy and the dynamic growth in emerging economies around the world, most notably China, how should the United States respond in order to maintain its position of leadership in the international system? This research paper examines the nature of economic globalization, the shift from a unipolar to multipolar international environment, and the potential impact on United States#65533; national security. It draws its conclusions from an extensive review of current literature covering globalization, political economics, and grand strategy. It examines William Scheuerman#65533;s four characteristics of the globalization phenomenon, globalization#65533;s effect on economics, and the interrelatedness of economic vitality and national strength, and concludes that a liberal internationalist approach is the best path forward for United States grand strategy. Because of interdependency brought about by globalization, cooperative global governance must replace the coercive democratization approach the United States has followed over the last decade. If pursued with the same vigor the United States demonstrated in Iraq and Afghanistan, the United States can rebuild its economic foundation and ensure a peaceful transition to a multilateral world order.
