The White House (via OMB) strongly protests Congressional efforts within the FY 2027 NDAA to prohibit the purchase of warships from foreign shipyards. The Administration argues that these restrictions undermine national security by limiting flexibility and hindering its strategy of leveraging allied yards, such as in the 'Finland model,' to drive investment into U.S. shipbuilding capacity. This signals a significant policy shift toward integrating international partners into advanced naval construction, suggesting the Pentagon is prepared to bypass traditional domestic build requirements for future combat vessels.
AI, 7-OH, and the Illusion of Scientific Uncertainty
English Summary
This article argues that large language models frequently project unwarranted certainty about contested scientific questions, particularly in public health debates. Using 7-hydroxymitragynine (7-OH), an alkaloid in kratom, as a case study, the author demonstrates how AI systems confidently describe it as a highly potent opioid with serious overdose risks, while recent scientific literature reveals ongoing debate about its pharmacology and safety profile—with evidence suggesting more complex, atypical receptor signaling and rare fatal overdoses. LLMs are trained to provide confident syntheses rather than distinguish between settled science and ongoing controversies, risking the amplification of moral panics around emerging substances. The author argues against regulatory approaches to resolve scientific disagreement and instead advocates for transparency about uncertainty, continued open debate, and scrutiny of confident claims from all sources. Policymakers considering substance restrictions should recognize that today's scientific controversy may become tomorrow's accepted therapy.
中文摘要
本文論述大型語言模型（LLMs）在處理爭議性科學問題，特別是在公共衛生辯論中，經常會呈現出不必要的確信。作者以克拉托姆（kratom）中的鹼化合物7-羥基米特拉庚質（7-OH）為案例，展示了人工智慧系統如何自信地將其描述為具有嚴重過量風險的高度效力鴉片類藥物。然而，最新的科學文獻卻揭示了其藥理學和安全性方面仍在持續爭論——證據顯示其可能存在更為複雜、非典型的受體訊號傳導，且致命過量案例極為罕見。LLMs的訓練目的在於提供自信的綜合性描述，而非區分已定論的科學事實與正在進行的爭議，這有時會導致圍繞新興物質產生道德恐慌的放大化。作者反對以監管方式來解決科學分歧，反而主張應提高關於不確定性的透明度、維持持續的公開辯論，並對所有來源的自信聲明進行嚴格審查。對於考慮實施物質限制的政策制定者而言，必須認識到，今日的科學爭議，可能就是明日被接受的療法。

The Western Pacific remains a highly active theater defined by sustained U.S.-led military exercises and escalating great power competition. Key evidence includes continuous joint operations, such as RIMPAC 2026 in Hawaii and the deployment of CSGs into the South China Sea, juxtaposed with increased naval activity from both China (PLAN task groups) and Russia near Japan's critical straits. These movements underscore a strategic push by non-allied powers to assert presence and challenge regional norms. Policy implications dictate that allied nations must maintain robust multilateral cooperation and interoperability to safeguard freedom of navigation and manage escalating tensions in the Indo-Pacific.

The article argues that the post-Cold War era of U.S. unipolarity, established by the perceived invincibility demonstrated during the Gulf War, has ended. This decline is driven by globalization and technological diffusion, which have democratized advanced military capabilities, allowing regional actors to challenge major powers. Consequently, policymakers must prepare for a more volatile international order marked by frequent crises, heightened costs for securing global trade chokepoints, and reduced predictability from American power. The new rules dictate that great powers can no longer effortlessly impose their will through force.

The article argues that current market borrowing costs are rising independently of the Federal Reserve's policy stance, challenging the assumption that the Fed controls all rates. Evidence shows significant increases in key rates—such as 2-year Treasuries and mortgages—even while the effective federal funds rate remains steady. This divergence occurs because market rates reflect complex factors like inflation expectations, credit risk, and geopolitical volatility, which are outside the central bank's direct control. Policymakers should therefore recognize that sustainable rate moderation requires credible disinflation and disciplined government budgets, rather than relying solely on Fed intervention.

Mini cities are temporary, child-run educational models—originating in Germany and Austria—that simulate real civic life by having children manage businesses, elect officials, pay taxes, and handle legal disputes. The core argument is that these hands-on experiences provide a superior learning environment compared to conventional schooling because children learn through the natural consequences of their actions rather than abstract grades. Policy implications suggest expanding this model from temporary summer programs into permanent, year-round structures that blur the line between play and real economic activity, potentially serving as a comprehensive 'launching pad' for future adult careers.
