English Summary

The article argues that global population aging and shrinking working-age populations will fundamentally constrain the capacity of major states to wage war, leading to a potential 'geriatric peace.' This theory is supported by demographic trends, such as China's projected dramatic decline in its working-age population, which limits both resources and manpower for conflict. While acknowledging that demographic factors are not deterministic—citing Russia's invasion of Ukraine as a counterexample—the analysis suggests that these limitations will dampen the pressures for large-scale great power conflict, particularly between the US and China. Policymakers should factor demographic decline into long-term strategic planning, recognizing it as a structural brake on military escalation.

中文摘要

本文提出,全球人口老齡化和勞動人口萎縮將從根本上限制主要國家發動戰爭的能力,從而可能導致一種潛在的「老年和平」(geriatric peace)。該理論得到人口結構趨勢的支持,例如中國預計的勞動人口急劇下降,這限制了衝突所需的資源和人力。儘管文章承認人口結構因素並非決定性因素——並以俄羅斯入侵烏克蘭作為反例——但分析指出,這些限制將減緩大國發生大規模衝突的壓力,特別是美中之間。政策制定者應將人口結構下降納入長期戰略規劃,將其視為限制軍事升級的結構性制動。

    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.
