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.
Spheres by Default
English Summary
The article argues that the concept of great power spheres of influence has evolved beyond traditional military boundaries, now manifesting in functional domains like critical technology and digital infrastructure. This shift allows powerful states, such as China, to consolidate an 'open sphere' by leveraging economic and technological influence, particularly if the United States makes unilateral concessions or is strategically distracted. The author warns that the U.S.'s willingness to make policy concessions regarding Taiwan and its diminishing reliability as a security guarantor could hasten China's consolidation of influence in the Indo-Pacific. Strategically, this necessitates that Washington update its understanding of modern spheres to prevent a major geopolitical division that could escalate into conflict.
中文摘要
本文論述「大國勢力範圍」的概念已超越傳統的軍事邊界，現已體現在關鍵技術和數位基礎設施等功能領域。這種轉變使得像中國這樣的強權國家，能夠透過經濟和技術影響力，鞏固一個「開放領域」，特別是當美國做出單邊讓步或在戰略上分心時。作者警告，美國在台灣問題上願意做出政策讓步，以及其作為安全保障提供者可靠性的下降，可能會加速中國在印太地區的勢力鞏固。從戰略角度來看，這要求華盛頓必須更新其對現代勢力範圍的理解，以避免導致可能升級為衝突的重大地緣政治分裂。

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.
