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.
Standards-Aligned Instructional Materials Use and Science Practices in K–12 Schools: Findings from the Spring 2025 American Instructional Resources Survey
English Summary
K-12 science teachers are significantly less likely to use standards-aligned instructional materials (10-24% adoption) compared to ELA and math teachers (49-66%), driven by a critical shortage of quality-rated science curricula and greater teacher autonomy in material selection. The supply gap is stark: only 2-5 green-rated science materials are available per grade level versus 26-35 for ELA/math, forcing many teachers to rely on self-created or unvetted materials. While science teachers using standards-aligned materials report greater student engagement in recommended science and engineering practices, they also perceive these materials as too challenging and routinely modify them, potentially reducing implementation fidelity. Expanding the supply of rated science curricula, establishing district-level guidance on material adoption, and providing professional development on standards-aligned instruction could address these systemic gaps and improve science achievement nationally.
中文摘要
K-12科學教師使用符合標準的教學材料的可能性遠低於英語文學藝術和數學教師(採用率分別為10-24%對49-66%)，這主要由於高品質評等的科學課程嚴重短缺，以及教師在教材選擇上擁有更大的自主權所致。供應缺口顯著：每個年級級別僅有2-5種綠色評等的科學教材，而英語文學藝術和數學教材則為26-35種，迫使許多教師依賴自行編製或未經審驗的教材。雖然使用符合標準教材的科學教師反映學生在推薦的科學與工程實踐中的參與度更高，但他們也認為這些教材過於困難，並經常對其進行修改，可能降低實施忠實度。擴大評等科學課程的供應、建立地區層級的教材採用指導，以及提供符合標準教學的專業發展，可以解決這些系統性缺口，並改善全國科學成就。

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.

Despite recent trade setbacks, the U.S. retains fundamental structural economic leverage over China, particularly in high-tech sectors and intermediate goods. While Beijing can temporarily weaponize specific resources like rare earths, these chokepoints are vulnerable to diversification efforts by the West. The article argues that the most effective strategy is not unilateral action but coordinated multilateral pressure from U.S. allies across Asia and Europe. Washington must therefore coordinate its economic statecraft with partners to maximize damage to China’s export-dependent model.
