English Summary

The 2026 assessment argues that the U.S. faces a complex and unpredictable terrorism landscape, moving away from a single paramount threat. Key evidence points to growing strength among formal al Qaeda and ISIS affiliates in the Middle East and Africa, while the domestic threat stems primarily from loose networks and lone actors motivated by niche ideologies. Policy implications suggest that counterterrorism strategies must adapt to this varied threat profile, especially as the U.S. simultaneously reduces overall investment in the field.

中文摘要

2026年的評估報告指出,美國面臨一個複雜且不可預測的恐怖主義格局,其威脅已遠離單一的首要威脅。關鍵證據顯示,中東和非洲地區的正式隸屬於基地組織(al Qaeda)和伊斯蘭國(ISIS)的分支機構正在增強實力;而國內的威脅則主要源於受利基意識形態驅動的鬆散網絡和單人行動者。政策啟示表明,反恐戰略必須適應這種多樣化的威脅態勢,尤其是在美國同時減少對該領域整體投資的背景下。

    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.
