English Summary

The U.S. Navy established two new commands at HMAS Stirling in Western Australia—Submarine Squadron 3 and Naval Support Activity Stirling—to support Submarine Rotational Force-West (SRF-West), a trilateral AUKUS initiative enabling U.S. and U.K. nuclear submarines to operate from Perth beginning in 2027. This infrastructure will maintain up to five rotational submarines while building Australia's indigenous maintenance workforce and supporting its development of a sovereign nuclear-powered attack submarine fleet under AUKUS Pillar 1. The arrangement enhances U.S. submarine readiness and regional presence in the Indo-Pacific while reducing burden on U.S. shipyards, as demonstrated by recent successful maintenance of HMS Anson using local Australian suppliers and advanced manufacturing techniques. This model establishes sustainable trilateral submarine operations aligned with non-proliferation standards and accelerates Australia's capability to own, operate, and maintain its own SSNs.

中文摘要

美國海軍在西澳的HMAS Stirling設立了兩個新司令部——潛艇中隊3和海軍支援設施Stirling——以支持「潛艇輪調部隊-西部」(SRF-West)。這是一個三邊合作的AUKUS倡議,將使美國和英國的核動力潛艇從珀斯開始運營,時間為2027年。此基礎設施將能夠維護多達五艘輪調潛艇,同時建立澳洲本土維護人才,並支持其根據AUKUS第一支柱發展自主的核動力攻擊潛艇艦隊。此安排提升了美國的潛艇戰備狀態和在印太地區的區域存在感,同時減輕了美國船廠的負擔。這體現在近期成功利用本地澳洲供應商和先進製造技術維護了HMS Anson。此模式建立了一種符合不擴散標準的可持續三邊潛艇運營機制,並加速了澳洲擁有、操作和維護自身SSN(核動力攻擊潛艇)的能力。

    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.
