English Summary

The article argues that the current US foreign policy is undergoing a 'postliberal' shift, moving away from adherence to the rules-based international order and toward a model rooted in raw power politics. This shift is evidenced by the revival of doctrines like the Monroe Doctrine and the emphasis on 'hardnosed realism' in the 2026 National Defense Strategy. The policy signals a preference for unilateral action and power balancing over multilateral cooperation or international norms. Policymakers should anticipate a strategic pivot that prioritizes immediate national power interests, potentially complicating traditional diplomatic alliances.

中文摘要

本文論述當前美國的外交政策正經歷一場「後自由主義」轉變,其趨勢是從遵循基於規則的國際秩序,轉向以原始權力政治為根基的模式。這一轉變的證據包括門羅主義等學說的復興,以及在2026年《國防戰略》中對「堅硬現實主義」的強調。此一政策訊號表明,美國傾向於單邊行動和權力平衡,而非多邊合作或國際規範。政策制定者應預期一場戰略轉向,該轉向將優先考慮眼前的國家權力利益,這可能會使傳統的外交聯盟面臨複雜化。

    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.
