The article argues that the Federal Reserve's recent rate hike decision, while justifiable on inflation grounds, highlights a critical lack of an underlying, transparent policy framework. The core problem is that the Fed's decisions appear discretionary, leading to market uncertainty because the committee's judgment, rather than clear data, dictates policy shifts. The author proposes that the Fed adopt a formal monetary policy rule—an algebraic formula linking the target rate to indicators like inflation and unemployment—to replace subjective guidance. Implementing such a rule would provide market predictability, enhance transparency, and shield the Fed from political attacks by making deviations from the standard easily quantifiable.
Supply Chain, Energy, and AI Nexus: Evaluating AI Energy Supply Chain Vulnerabilities
English Summary
The rapid expansion of AI data centers creates immense power demands that threaten U.S. grid reliability and capacity. RAND analyzed critical electrical equipment across generation, transmission, and backup systems, finding that supply chain vulnerabilities are a major constraint on meeting future energy needs. The research found that generation components exhibit systematically higher vulnerability scores than standardized transmission parts, with risks varying significantly by specific component (e.g., market concentration vs. volume volatility). Consequently, policymakers must implement highly tailored supply chain resilience strategies and targeted interventions for each vulnerable component to ensure AI development can proceed without critical infrastructure bottlenecks.
中文摘要
人工智慧（AI）資料中心的快速擴張產生了巨大的電力需求，威脅到美國電網的可靠性與容量。RAND 分析了涵蓋發電、輸電和備用系統等關鍵電氣設備，發現供應鏈脆弱性是滿足未來能源需求的重大制約。研究指出，發電組件的脆弱性評分系統性地高於標準化的輸電部件，且風險因具體組件而異（例如：市場集中度與銷量波動性）。因此，政策制定者必須為每個易受攻擊的組件實施高度定制化的供應鏈韌性策略和目標性干預措施，以確保AI發展能夠在不遭遇關鍵基礎設施瓶頸的情況下持續進行。

The ongoing Ebola outbreak in the DRC serves as a critical warning that the global health security system is fundamentally unprepared for future biological threats. The difficulty in containing this outbreak is compounded by the rising risk of emerging pathogens and the growing potential for AI misuse in bioweapon development. Policy must therefore shift from reactive, crisis-driven funding to sustained, proactive investment in resilient public health infrastructure, particularly in conflict zones. Addressing this requires strengthening global surveillance, ensuring consistent international cooperation, and mitigating the intersection of conflict, climate change, and disease spread.

3.A Design Lab Pilot to Inform Strategies for Expanding Access to Medications for Opioid Use Disorder in Community Mental Health Centers (RAND)
Despite MOUD being the standard of care for opioid use disorder, access remains severely limited in Community Mental Health Centers (CMHCs), which serve the primary population with co-occurring disorders. A Design Lab pilot identified payment limitations and regulatory complexity as the chief barriers to implementation. The most feasible and high-impact strategy identified was establishing a structured learning exchange between CMHC leaders and insurers to improve reimbursement understanding. Policymakers and payers are therefore advised to pilot this learning exchange model to initiate broader payment reform and expand evidence-based care for this vulnerable population.

The article argues that modern conflicts are increasingly defined by attrition, driven by three strategic gaps: the difference between nominal military power and usable capacity; the difficulty of achieving breakthroughs in a technologically advanced battlefield; and the detachment of military means from clear political objectives. Evidence from Ukraine and the Middle East demonstrates that sustained logistics, rapid technological adaptation, and proxy networks are now more decisive than sheer military size. For policymakers, this implies a strategic shift away from seeking short, decisive victories toward preparing for prolonged, high-cost engagements, requiring a focus on sustainable supply chains and defining concrete, attainable political end-states.

Congress has significantly expanded presidential tariff authority by passing the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, allowing the executive to impose up to 100% tariffs on key buyers of Russian energy and sanctions enablers. The article argues that this legislation represents a dangerous abdication of Congress's Article I authority, as it grants the executive vast, discretionary power without specifying criteria for enforcement. Historically, the executive could claim tariffs were its own doing; however, by writing and passing this new authority, Congress now owns the resulting trade policy and its economic consequences. This shift implies that future tariffs will be viewed by the public as a direct legislative action, potentially undermining the administration's credibility and creating political vulnerability.
