English Summary

Analysis of post-1945 conflicts suggests that war is historically ineffective for achieving lasting security, wealth, or status, as states initiating conflict tend to fail their objectives. The primary driver for continued military action, however, is not material necessity but rather political miscalculation. Leaders often succumb to psychological biases and overconfidence, leading them to overestimate their chances of success despite available evidence of failure. This persistent desire among great powers for elevated status and prestige remains the most significant predictor of future conflict, regardless of the high costs involved.

中文摘要

對戰後1945年以來的衝突分析顯示,戰爭在實現持久安全、財富或地位方面,歷來是徒勞無功的。因為發起衝突的國家往往無法達成其既定目標。然而,持續進行軍事行動的主要驅動力,並非物質上的必要性,而是政治上的誤判。領導人常受心理偏差和過度自信的影響,導致他們即使面對失敗的證據,仍會高估自身成功的機率。這種大國對於提升地位和聲望的持續渴望,無論其代價多高,仍是預測未來衝突最關鍵的指標。

    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.
