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.
Chokepoints and coercion: Iran’s challenge to maritime openness
English Summary
Iran has introduced politically conditioned access to the Strait of Hormuz by selectively granting passage to vessels from allied nations (Russia, China, Pakistan) while charging tolls and requiring detailed information about ownership and crew nationality, directly challenging the 400-year-old principle of freedom of navigation. This represents a significant precedent for using maritime chokepoints as geopolitical leverage that could spread to other critical waterways like the Strait of Malacca and Taiwan Strait. Such politicization would harm smaller, trade-dependent countries most severely and shift global commerce from economically-determined to geopolitically-determined criteria, requiring major powers to sustain open transit through credible deterrence, transparency mechanisms, and resistance to competing systems of privileged access. The implications extend beyond immediate energy disruptions to fundamentally reshape how states use control of critical infrastructure for coercive purposes in an era of intensifying geopolitical rivalry.
中文摘要
伊朗透過選擇性地向盟國（如俄羅斯、中國、巴基斯坦）船隻提供霍爾木茲海峽的通行權，同時收取過路費並要求提供詳細的船隻所有權和船員國籍資訊，實行了政治條件化的海峽進入權。此舉直接挑戰了數百年來確立的航行自由原則。這代表著一個重大的先例，即將海域咽喉點作為地緣政治籌碼，其影響可能擴散至馬六甲海峽和台灣海峽等其他關鍵水道。此類政治化行為將最嚴重損害小型、依賴貿易的國家，並將全球商業的決定標準從經濟因素轉移至地緣政治因素。這要求主要大國必須透過可信的威懾、透明化機制，以及對競爭性特權通行體系的抵抗，來維持開放的過境權。其意涵不僅限於即時的能源供應中斷，更將從根本上重塑國家在日益激烈的地緣政治競爭時代，利用關鍵基礎設施進行強制性目的的手段。

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.
