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.
Redrawing global boundaries? The United States, China, and the viability of spheres of influence in the 21 st century
English Summary
Brookings’ expert roundtable argues that a U.S. "Donroe Doctrine" push for hemispheric primacy is more likely to weaken than strengthen Washington’s position in long-term competition with China, though one contributor contends it could restore deterrence by denying Beijing footholds near U.S. borders. The dominant reasoning is that coercive regional tactics and unilateral moves drain U.S. military bandwidth from the Indo-Pacific, damage alliances, and erode soft power while giving China narrative and diplomatic advantages. Experts also note China’s already deep regional footprint, including major trade, investment, and infrastructure ties across Latin America, which makes a clean spheres-of-influence rollback unrealistic. Strategically, a formal U.S.-China spheres bargain is assessed as unstable and asymmetric: it could pressure smaller states to hedge, accelerate regional militarization and possible nuclear proliferation, and incentivize revisionist claims elsewhere, suggesting U.S. policy should prioritize alliance credibility, rules-based coordination, and positive economic alternatives over coercion.
中文摘要
布魯金斯學會的專家圓桌認為，美國若以「Donroe Doctrine」推動西半球主導權，在與中國的長期競爭中更可能削弱而非強化華府地位；但也有一位與談人主張，透過阻止北京在美國邊境周邊建立立足點，或可恢復嚇阻力。主流論點指出，脅迫性的區域手段與單邊作為會分散美軍在印太的兵力與注意力、損害同盟關係、侵蝕軟實力，並讓中國在敘事與外交上取得優勢。專家也強調，中國已在該區形成深厚布局，包括在拉丁美洲廣泛的貿易、投資與基礎設施連結，使「勢力範圍」的全面回退並不現實。從戰略上看，正式的美中勢力範圍交易被評估為不穩定且不對稱：它可能迫使中小國採取避險策略、加速區域軍備化甚至核擴散風險，並激勵他處的修正主義主張；因此，美國政策應優先強化同盟可信度、以規則為基礎的協調，以及具吸引力的正向經濟替代方案，而非依賴脅迫。

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.
