English Summary

The article argues that Russia's prolonged war in Ukraine and the U.S.'s 2026 Iran conflict have revealed the limits of superpower dominance, as both Putin and Trump's military miscalculations have trapped them in costly, unwinnable conflicts that are undermining their global credibility. Ukraine and Iran, despite being militarily weaker, have inflicted massive casualties and costs on their attackers, forcing both superpowers to recognize they cannot impose their will and are losing traditional allies seeking independent security arrangements. The simultaneous distraction of both superpowers is accelerating a shift toward decentralized global security, with Europe recognizing Ukraine as a credible military asset and developing independent defense capabilities rather than relying on American guarantees. The article recommends that regional groupings like the Joint Expeditionary Force take a leading role in security coordination and that Europe facilitate an end to the Russia-Ukraine war independent of U.S. involvement.

中文摘要

本文論述,俄羅斯在烏克蘭持續的戰爭以及美國預計於2026年發生的伊朗衝突,已揭示了超級大國主導地位的極限。由於普丁和川普兩人的軍事誤判,他們被困於成本高昂且難以取勝的衝突中,這正在削弱其全球公信力。烏克蘭和伊朗儘管軍事力量較弱,卻對攻擊方造成了巨大的傷亡和經濟損失,迫使兩大超級大國意識到,它們無法強加自己的意志,並且正在失去傳統盟友,這些盟友正尋求獨立的安全安排。兩大超級大國同時分心,正在加速推動全球安全模式向去中心化轉移。歐洲正在將烏克蘭視為一個可信的軍事資產,並發展獨立的國防能力,而非依賴美國的保證。本文建議,像聯合遠征部隊(Joint Expeditionary Force)這樣的區域性集團應在安全協調中發揮主導作用,並且歐洲應促成一場獨立於美國參與的俄烏戰爭終結。

    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.
