English Summary

The IISS paper argues that cloud computing is becoming essential for national-security and defence functions in the Asia-Pacific, and that states can combine commercial cloud benefits with sovereign control. Using case studies of Japan, the Philippines, Singapore, and Thailand, it shows each country adopting hybrid or phased models to handle growing data demands, improve military interoperability, and strengthen decision-making under complex cyber and geopolitical pressure. The analysis highlights that reliance on dominant hyperscalers, especially US providers, creates governance and control trade-offs that governments are managing through tailored technical, legal, and institutional safeguards. Strategically, the paper implies that effective NS&D cloud policy should prioritize secure hybrid architectures, domestic governance capacity, and clear sovereignty mechanisms rather than seeking full digital isolation.

中文摘要

IISS 的論文指出,雲端運算正逐漸成為亞太地區國家安全與國防職能的關鍵基礎,且各國可在運用商業雲優勢的同時維持主權控制。透過日本、菲律賓、新加坡與泰國的案例研究,報告顯示各國正採取混合式或分階段模式,以因應日益增加的資料需求、提升軍事互通性,並在複雜的網路與地緣政治壓力下強化決策能力。分析強調,對主導性超大規模雲端服務商(尤其是美國供應商)的依賴,會帶來治理與控制層面的權衡;各國政府正透過量身設計的技術、法律與制度性防護機制加以管理。就戰略層面而言,該論文意涵在於:有效的國安與國防雲端政策,應優先聚焦於安全的混合式架構、國內治理能力,以及明確的主權機制,而非追求完全的數位孤立。

    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.

    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.
