English Summary
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.
中文摘要
中國AI模型透過開放權重發布，在編碼和代理任務等領域展現出高性能，正迅速縮小與美國前沿模型的能力差距。此快速進展得益於知識蒸餾等技術，以及開源社群的去中心化性質，使得中國實驗室能夠以低於封閉式美國API的成本開發出具競爭力的模型。從策略角度來看，這迫使美國必須將重點從單純領先的模型能力，轉移到確保「美國AI堆棧」在全球範圍內被採用。為維持全球領導地位，美國政策必須優先考慮建立信任和降低定價門檻，因為外國參與者將會分散投資，避開不可預測或成本過高的美國供應商。

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.

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.

While the US has opted not to renew the USMCA for a full term, triggering an annual review process until 2036, this non-renewal does not signal the end of North American integration. The continued economic dependence—which supports trillions in trade and millions of jobs—makes withdrawal highly unlikely despite political tensions and tariff threats. Strategically, businesses must prepare for prolonged uncertainty and protracted negotiations across multiple sectors (e.g., auto rules, digital trade). Policymakers should focus on managing the ongoing review process to mitigate supply chain disruption and address shared concerns regarding Chinese overcapacity in the region.
