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.
Evaluating Large Language Models' Abilities to Process and Understand Technical Policy Reports
English Summary
This RAND report details the development of a specialized benchmark to accurately evaluate Large Language Models (LLMs) on complex, technical policy reports. The authors found that standard LLMs perform poorly (48-54% accuracy) on nuanced policy claims, demonstrating that out-of-the-box solutions are insufficient for high-stakes decision support. To improve reliability, the report recommends moving beyond binary truth assessments, utilizing multi-category truthfulness metrics to capture partial inaccuracies and inferred reasoning. Strategically, while LLMs hold promise for synthesizing policy findings and identifying evidence gaps, their deployment requires significant domain-specific fine-tuning and rigorous testing before they can be trusted by public decision-makers.
中文摘要
這份RAND報告詳述了開發一套專門的基準評估工具，用於準確評估大型語言模型（LLMs）在複雜、技術性政策報告上的表現。作者發現，標準LLMs在處理細LLM的政策論點時表現不佳（準確度為48-54%），證明了現成的解決方案不足以用於高風險決策支援。為提高可靠性，報告建議超越二元真值評估，轉而利用多類別真實性指標，以捕捉部分不準確性和推論推理。從戰略角度來看，儘管LLMs在綜合政策發現和識別證據缺口方面具有巨大潛力，但其部署必須經過大量的領域特定微調和嚴格測試，才能讓公眾決策者信任。

This RAND report assesses how energy and water technologies can sustain rapid, agile U.S. Air Force operations in contested environments. The analysis finds that near-term operational resilience is achievable through advancements in existing systems, such as improved batteries, vehicle-to-grid integration, and atmospheric water harvesting. While transformational solutions like fusion power or microreactors are progressing, they remain early stage and face significant regulatory challenges. Strategically, the findings imply a dual focus: immediate investment in maturing current technologies for deployability, alongside sustained R&D into advanced systems to ensure long-term military energy and resource independence.

The RAND report argues that China's massive Strategic Petroleum Reserve (SPR), estimated at 1.1–1.4 billion barrels, represents a potential geoeconomic tool far exceeding its function as a mere energy security buffer. Key to this leverage is the state's unique control over both government and commercial reserves, allowing for flexible intervention during global supply shocks. This capacity could enable Beijing to influence international oil markets, project power, or punish adversaries by strategically releasing or withholding reserves. Policymakers must therefore anticipate scenarios where China utilizes its energy assets not just for domestic stability, but as a primary instrument of foreign economic policy and geopolitical leverage.

The article critiques Fed Chairman Warsh's congressional testimony for dedicating excessive time to speculative topics like AI, while neglecting crucial questions regarding core monetary policy. Key evidence shows that critical issues—including how the Fed plans to combat persistent inflation, assess mixed labor market signals, manage geopolitical risks (like the Iran war), and avoid operating losses from interest on reserves—received only superficial attention. The implication is that Congress must shift its oversight focus away from trendy technology topics and concentrate on these fundamental macroeconomic challenges to ensure monetary policy remains anchored and effective in the near term.

5.Examining the Impact of Senate Bill 1160 on Utilization Review and Medical Treatment in California Workers' Compensation (RAND)
This RAND report evaluates whether California's Senate Bill 1160 successfully reduced administrative burdens and improved timely care in workers’ compensation by limiting utilization review (UR) requirements for certain treatments within the first 30 days of injury. Using large-scale claims data, the analysis assesses changes in UR approval rates, adherence to medical guidelines, and time-to-treatment before and after the law's implementation. Initial findings indicate that UR approval rates remained consistently high across both periods, suggesting the impact on authorization processes may be minimal for certain treatments. Overall, the study provides critical empirical data intended to guide policymakers (like the California Department of Industrial Relations) in refining workers’ compensation policy to balance timely medical access with necessary oversight.
