The article outlines how a successful modern foreign policy career requires blending traditional diplomatic expertise with private sector acumen. Juster's career trajectory—from international law to high-stakes diplomacy (e.g., the Gulf War) and subsequently to the technology sector—demonstrates this synthesis. Key evidence includes his work managing complex negotiations under duress and his involvement in co-founding the U.S.-India High Technology Group. The implication for policy is that effective geopolitical strategy must actively integrate private sector knowledge and technological considerations to manage modern economic and security challenges.
US foreign policy
English Summary
Chatham House argues that US global influence remains substantial but is increasingly perceived as declining, particularly in economic terms, as China, India and Russia gain weight. The analysis points to policy volatility and experimentation across major dossiers, including the Trans-Pacific Partnership, the Paris climate accord, the Iran nuclear deal, and relations with the EU, Russia and North Korea. At the same time, persistent transnational challenges such as trade, climate change, nuclear risk and terrorism are presented as areas where US engagement is still indispensable. The strategic implication is that Washington’s credibility will depend less on unilateral dominance and more on consistent, coalition-based leadership in managing shared global risks.
中文摘要
研究所認為，美國的全球影響力仍然可觀，但外界愈發認為其影響力正在下降，尤其在經濟層面；與此同時，中國、印度與俄羅斯的分量上升。分析指出，美國在多項重大議題上的政策呈現波動與試驗性調整，包括《跨太平洋夥伴協定》、巴黎氣候協定、伊朗核協議，以及與歐盟、俄羅斯和北韓的關係。與此同時，貿易、氣候變遷、核風險與恐怖主義等持續性的跨國挑戰，仍被視為美國參與不可或缺的領域。其戰略意涵在於：華盛頓的可信度將較少取決於單邊主導，而更取決於能否以一致且以聯盟為基礎的領導方式，管理共同的全球風險。

The analysis suggests that Russia's ability to sustain its war effort in Ukraine is facing increasing internal and external pressures. Key evidence points to a tightening economic crisis, evidenced by widespread blackouts and a noticeable scaling back of traditional military displays. Furthermore, the discussion highlights Putin's increasing isolation and micromanagement, suggesting that the strategic initiative may be slipping out of Moscow's control. Policymakers should monitor these signs of internal strain, as they indicate potential vulnerabilities and a possible shift in Russia's military and geopolitical calculus.

The Brookings report argues that closing long-term fiscal deficits cannot be achieved solely by taxing high earners or corporations. Analysis shows that the required savings necessitate broad-based tax increases that would significantly impact middle and lower-income families, as targeted taxes on the wealthy are insufficient. The report notes that high-tax OECD nations achieve high revenues through broad consumption taxes (like VAT) rather than exclusively through highly progressive taxes on the rich. Consequently, any major tax-funded deficit solution would impose a substantial burden on the working class, potentially without the comprehensive social benefits enjoyed by European counterparts.

The analysis concludes that China will hold the upper hand at the upcoming Trump-Xi summit, leveraging its dominance over critical minerals, rare earths, and magnet supply chains. This geopolitical leverage, combined with global instability (such as the Iran conflict), allows Beijing to dictate terms and buy time to consolidate its technological and industrial self-sufficiency. Strategically, the U.S. must avoid granting China a managed equilibrium by maintaining 'maximum pressure' on key sectors like AI and tech, rather than seeking broad agreements that could undermine American leadership.

The article argues that the ongoing Iran War has triggered a severe global hunger crisis, exacerbated by U.S. aid cuts and policy neglect, pushing millions to the brink of starvation. Key evidence includes the termination of U.S. support in countries like Afghanistan, Somalia, and Yemen, coupled with supply chain disruptions and massive cost increases across the region. Policy recommendations are urgent: the U.S. must immediately deploy its $5.4 billion in unspent humanitarian funds, establish a humanitarian corridor through the Strait of Hormuz, and reinstate life-saving aid to critical nations.
