English Summary

The Supreme Court recently upheld the constitutional guarantee of birthright citizenship in the United States, rejecting executive efforts to restrict it under the Fourteenth Amendment. This ruling affirms the long-standing *jus soli* principle, which grants U.S. citizenship to nearly anyone born within the nation's territory. While critics argue that this practice encourages unauthorized migration, legal experts caution that repealing birthright status would require a difficult constitutional amendment and could counterproductively worsen immigration flows. Consequently, policy attempts to restrict citizenship at birth may fail legally and undermine existing legal pathways for current residents.

中文摘要

最高法院近期重申了美國憲法的出生公民權保障，駁回了行政部門試圖根據《第十四修正案》限制此權的努力。此裁決肯定了長期存在的「屬地原則」（jus soli），即授予在國土內幾乎任何出生者的美國公民身份。儘管批評者主張此做法會鼓勵非法移民，但法律專家警告稱，廢除出生公民權需要進行艱難的憲法修正案，且可能產生反效果，反而惡化移民流動。因此，試圖限制出生公民權的政策，在法律上可能會失敗，並損害現有居民的合法居留途徑。

CFR and Belfer Center Launch New Task Force on Energy Security, Technological Innovation, and American Leadership (CFR)

2026-07-06 | energy | 2026-W28 | Topics: China, United States

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.

What to Know About Chinese AI Models (CSIS)

2026-07-06 | tech | 2026-W28 | Topics: AI, China, Cybersecurity, Trade, United States

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.

How the Past Can Inform the Future of U.S. Foreign Policy (CFR)

2026-07-06 | diplomacy | 2026-W28 | Topics: China, Climate, Europe, Indo-Pacific, Middle East, NATO, Nuclear, Russia, Trade, United States

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.

A Year Later, Trump’s Big Beautiful Bill Act Has a Clean Tech Silver Lining (CFR)

2026-07-06 | energy | 2026-W28 | Topics: China, Climate, Nuclear, United States

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.
