English Summary

Chatham House argues that the post-1945 international order is under growing strain from renewed interstate aggression, coercive diplomacy, and great-power competition over future global rules. It reasons that credibility gaps—such as perceived Western double standards on Ukraine and Gaza—and a more transactional US foreign policy are accelerating institutional fragmentation. The centre’s approach is to identify which legacy norms can be preserved, where new rules are needed, and how to give greater weight to smaller states, aspiring middle powers, and Global South voices across security, law, digital, and health domains. For policymakers, the implication is that effective strategy now requires pragmatic institutional reform and broader coalition-building, rather than reliance on legacy governance frameworks alone.

中文摘要

查塔姆研究所指出,1945年後形成的國際秩序正日益承受壓力,主因在於國家間侵略行為再起、脅迫式外交,以及大國對未來全球規則主導權的競爭。該機構認為,可信度落差——例如外界對西方在烏克蘭與加薩議題上採取雙重標準的觀感——再加上美國外交政策更趨交易化,正加速制度性碎片化。其研究取徑在於辨識哪些既有規範可予以維持、哪些領域需要新規則,並在安全、法律、數位與公共衛生等面向提升小型國家、崛起中的中等強國與全球南方聲音的權重。對決策者而言,其政策意涵是:有效戰略如今須倚賴務實的制度改革與更廣泛的聯盟建構,而非僅依靠既有治理框架。

    The China-Russia partnership is a highly consequential geopolitical alignment driven by a shared goal of countering U.S. hegemony and reshaping the international order into a multipolar system. While not a formal alliance, this relationship is strengthened by Russia's increasing economic reliance on China following Western sanctions, which allows Beijing to leverage its influence. Policymakers should note that while the partnership projects deep solidarity (as seen in high-level summits), it remains complex and limited by mutual mistrust and competing strategic interests. This enduring alignment poses a significant challenge to U.S. interests and requires continued diplomatic vigilance.

    The Chatham House analysis concludes that the UK's Defence Investment Plan (DIP) will be viewed by NATO allies as a mixed bag, primarily due to its failure to commit to higher GDP spending targets. However, the plan signals critical strategic improvements by emphasizing novel technologies—such as autonomous systems and digital infrastructure—and enhancing readiness. Crucially, the DIP adopts an international focus through major collaborative programs (e.g., AUKUS, GCAP) and establishes a new National Armaments Director Group (NADG). This structural shift toward flexible, portfolio-based collaboration is strategically valuable for NATO allies seeking reliable partners as US conventional forces reduce their European presence.

    The article argues that the U.S., through recent policy signals—such as questioning NATO's value or sympathizing with great-power territorial claims—is inadvertently adopting the core tenets of non-alignment, prioritizing transactional national interests over binding alliances. Historically, while non-alignment allowed developing nations to gain benefits without commitment, the analysis notes that this approach lacks the deep trust and shared obligations necessary for robust security structures. The implication is critical: by undermining established alliances, the U.S. risks losing its greatest strategic asset—the network of mutual commitments—as allies actively seek alternative bilateral or regional defense pacts.

    The roundtable established that implementing generational bans represents a powerful, long-term strategy for tackling deeply entrenched public health crises like tobacco use. Using the UK’s permanent ban on selling cigarettes to those born after 2009 as key evidence, experts analyzed how such policies fundamentally alter market dynamics and consumer behavior over time. These lessons suggest that other nations facing persistent addiction challenges should consider adopting similar age-gating or generational restrictions to accelerate decline and set a precedent for future public health policy interventions.

    The CSIS analysis finds that the U.S. grid's regulatory framework for connecting large loads is severely fragmented and unprepared for the massive electricity demands posed by AI data centers. FERC has mandated significant reforms across six regional operators, requiring them to modernize interconnection studies, prevent cost-shifting, and establish clear tariffs for co-located generation. Evidence shows that most operators fall far short of these new standards, necessitating complex, multi-year policy adjustments rather than simple compliance. Policymakers must coordinate federal regulation (FERC) with state utilities to accelerate grid modernization, ensuring energy affordability while maintaining technological competitiveness.
