English Summary
Robert Kagan argues that U.S. foreign policy is frequently misunderstood as isolationist when it is historically defined by constant global engagement. He refutes the myth of American neutrality, asserting that history shows continuous expansion and interaction with great powers, driven not by external threats but by internal forces. These persistent outward pulls include economic necessity (as a trading nation), universalist ideological values, and the natural consequence of accumulating power. The key implication for policy is that strategic planning must recognize this deeply ingrained pattern of global involvement—rather than viewing it as an occasional deviation from domestic isolationism—to accurately predict future American actions.
中文摘要
羅伯特·卡根論述，美國的外交政策經常被誤解為孤立主義，但其歷史定義卻是持續的全球參與。他反駁了「美國中立」的神話，指出歷史證明美國與大國之間存在著持續的擴張和互動，而這些驅動力並非來自外部威脅，而是源於內在力量。這些持久的外向拉力包括經濟需求（作為一個貿易國家）、普遍主義的意識形態價值觀，以及累積權力的自然結果。對政策而言，關鍵的啟示是：戰略規劃必須認識到這種根深蒂固的全球介入模式——而非將其視為偶爾偏離國內孤立主義的例外情況——才能準確預測美國未來的行動。

The CFR and Belfer Center launched a high-level Task Force asserting that U.S. long-term security hinges on three interconnected pillars: reliable domestic energy access, global leadership in emerging energy technologies, and sustained geopolitical leverage. The project aims to analyze how these factors interact to determine national strength in the modern era. By synthesizing expert insights, the Task Force will generate actionable policy recommendations designed to strengthen America's position within the global energy system. This signals a strategic imperative for policymakers to prioritize integrated initiatives that advance both technological innovation and U.S. leadership in clean energy markets.

This analysis reviews pivotal U.S. foreign policy decisions over 250 years, ranking them by their historical impact on global stability and American leadership. Key successes—such as the Marshall Plan, the creation of NATO, and the establishment of the Bretton Woods system—are attributed to proactive diplomacy and institutional building that stabilized post-war international order. The findings suggest that effective U.S. strategy relies heavily on establishing multilateral frameworks and managing geopolitical risks through careful statecraft. Ultimately, the article implies that historical analysis guides policy by emphasizing the necessity of strategic alliances and economic cooperation to maintain global influence.

Chinese AI models are rapidly closing the capability gap with U.S. frontier models, demonstrating high performance in coding and agent tasks through open-weight releases. This rapid progress is fueled by techniques like knowledge distillation and the decentralized nature of the open-source community, allowing Chinese labs to achieve competitive models at lower costs than closed US APIs. Strategically, this forces the United States to shift its focus from merely leading in model capability to ensuring global adoption of the 'American AI stack.' To maintain global leadership, U.S. policy must prioritize building trust and reducing pricing barriers, as foreign actors will diversify away from unpredictable or expensive American providers.

This CFR project analyzes two and a half centuries of U.S. foreign policy decisions, arguing that historical patterns offer crucial lessons for current strategic challenges. The core finding, derived from surveys of leading historians, identifies the Marshall Plan as the consensus best decision due to its stabilizing role in post-WWII Europe and its humanitarian impact. These findings imply that successful long-term U.S. strategy often involves large-scale diplomatic investments aimed at rebuilding key international partners or promoting regional stability. Policymakers should view historical success not just through military action, but through sustained efforts to stabilize global systems.

Despite critics labeling it a disaster for eliminating wind/solar credits, Trump's One Big Beautiful Bill Act may offer a clean tech silver lining by preserving incentives for less mature energy sources like advanced nuclear and geothermal power. The analysis argues that while expanding mature technologies has limited global impact, funding the high initial costs of emerging solutions allows them to benefit from a 'learning curve,' making them globally affordable later. These reliable, non-variable sources complement existing renewables and could establish a foundational clean energy capacity for the US. Strategically, this development provides a potential counterweight to China's current dominance in global clean energy supply chains.
