English Summary

The conflict in Ukraine demonstrates that modern great-power warfare is characterized by sustained, highly destructive conventional conflict and a fragile, elevated risk of nuclear escalation, rather than quick, decisive outcomes. While Russia's nuclear threats are significant, Ukraine's resilience and ability to strike deep into Russian territory show that nuclear weapons do not guarantee coercive leverage. Consequently, the U.S. must update its defense planning to prepare for protracted wars of attrition with nuclear-armed adversaries, focusing on strengthening deterrence, coordinating with allies, and maintaining readiness for extended, high-stakes conflicts.

中文摘要

烏克蘭的衝突顯示,現代大國層面的戰爭特徵是持續性、高度破壞性的傳統衝突,以及脆弱且升高的核升級風險,而非快速、決定性的戰果。儘管俄羅斯的核威脅極為重大,但烏克蘭的韌性及其深入俄羅斯領土的打擊能力表明,核武器並不能保證強制性的戰略籌碼。因此,美國必須更新其國防規劃,以應對與擁有核武的敵對方進行的長期消耗戰,重點應放在強化威懾、與盟友協調,以及維持應對長期、高風險衝突的戰備狀態。

    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.

    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.

    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.
