English Summary

Analysis of post-1945 conflicts suggests that war is historically ineffective for achieving lasting security, wealth, or status, as states initiating conflict tend to fail their objectives. The primary driver for continued military action, however, is not material necessity but rather political miscalculation. Leaders often succumb to psychological biases and overconfidence, leading them to overestimate their chances of success despite available evidence of failure. This persistent desire among great powers for elevated status and prestige remains the most significant predictor of future conflict, regardless of the high costs involved.

中文摘要

對戰後1945年以來的衝突分析顯示,戰爭在實現持久安全、財富或地位方面,歷來是徒勞無功的。因為發起衝突的國家往往無法達成其既定目標。然而,持續進行軍事行動的主要驅動力,並非物質上的必要性,而是政治上的誤判。領導人常受心理偏差和過度自信的影響,導致他們即使面對失敗的證據,仍會高估自身成功的機率。這種大國對於提升地位和聲望的持續渴望,無論其代價多高,仍是預測未來衝突最關鍵的指標。

    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.
