English Summary

The publication challenges the concept of 'geriatric peace,' arguing instead for an 'aging security dilemma' in East Asia. As aging populations cause states to fear military weakness, they compensate by rapidly developing advanced weapons and automation, thereby sustaining or intensifying their security posture. This arms race, exemplified by Japan's focus on advanced platforms, increases regional concern and creates a dangerous cocktail of tensions, especially when combined with cyber threats and shifting alliances. Policymakers must analyze how different Asian states adapt their military doctrines and procurement choices to anticipate and mitigate escalating regional instability.

中文摘要

該出版物挑戰了「老年和平」(geriatric peace)的概念,反而主張東亞存在著「人口老化安全困境」(aging security dilemma)。隨著人口老化,各國國家會恐懼軍事上的弱勢,因此透過快速發展先進武器和自動化技術來進行補償,從而維持甚至加劇其安全態勢。這場軍備競賽,以日本對先進平台的關注為例,增加了區域性的擔憂,並在結合網路威脅和不斷變化的聯盟關係時,形成了一種危險的緊張局勢。政策制定者必須分析不同亞洲國家如何調整其軍事學說和採購選擇,以預測並緩解日益升級的區域不穩定性。

    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.
