English Summary

The expiration of the New START treaty on February 5, 2026, marks the end of formal limits on U.S. and Russian nuclear arsenals, raising significant risks of a new arms race and strategic miscalculation. Experts warn that the loss of robust verification measures and on-site inspections will erode intelligence precision, likely prompting both superpowers to 'upload' reserve warheads onto existing delivery systems. To maintain stability, U.S. policy must balance necessary modernization—such as reopening submarine missile tubes—with the urgent pursuit of a follow-on agreement that ideally addresses non-strategic weapons and China's growing nuclear capabilities.

中文摘要

《新削減戰略武器條約》(New START)於 2026 年 2 月 5 日到期,標誌著美俄核武庫正式限制的終結,顯著增加了新一輪軍備競賽與戰略誤判的風險。專家警告,強力核查措施與現場視察的缺失將削弱情報精確度,可能促使兩大強權在現有運載系統上「裝載」預備彈頭。為維持穩定,美國政策必須在必要的現代化進程(如重新啟用潛艇飛彈發射管)與緊迫尋求後續協議之間取得平衡,且理想的協議應涵蓋非戰略性武器及中國日益增長的核能力。

    The rapid financing of the AI boom through massive corporate debt issuance is creating significant stress on global financial markets. This influx of private capital forces competition with government Treasury bonds, as AI companies offer higher yields than equivalent sovereign debt, thereby pushing up long-term interest rates. While this signals strong investment demand for AI, it raises concerns about systemic risk and the potential destabilization of core bond markets. Policymakers must navigate the tension between fueling critical technological growth and maintaining stable public borrowing costs to prevent a financial crisis.

    The article argues that while Ratko Mladić was convicted for the Srebrenica genocide, a second alleged campaign targeting Bosnian Muslims in six municipalities during 1992 is crucial to understanding his full criminal scope. Although the main trial judges acquitted him on the 1992 charge due to legal difficulties proving 'specific intent,' two dissenting appeals judges strongly argued that Mladić's high level of command and knowledge implied genocidal intent. This case highlights both the immense challenge in establishing genocide under international law—particularly proving specific intent—and underscores the critical importance of reviewing dissenting judicial opinions for setting future precedents in war crimes accountability.

    The Chatham House report argues that climate change represents Europe's greatest systemic security threat, citing recent extreme heatwaves, droughts, and wildfires that have caused massive economic losses, infrastructure failures, and excess deaths. These environmental shocks disrupt critical services (like energy supply) and increase vulnerability to non-conventional threats, forcing military resources to divert personnel away from traditional defense roles. To counter this, the report mandates a comprehensive security approach: treating climate adaptation as core national security spending, accelerating decarbonization to address root causes, and building robust societal resilience through coordinated civil preparedness.

    Six months after the U.S.-Israel attack on Iran, experts conclude that Washington has suffered a strategic defeat due to underestimating Iran's resilience and capacity for resistance. The conflict has significantly heightened regional instability, fueling sophisticated online propaganda from Tehran that creates a dangerous content advantage for radicalization efforts against U.S. interests. Furthermore, the war is paradoxically benefiting Turkey, which is consolidating its power through new regional security agreements, thus reducing overall U.S. influence in the Middle East. Policymakers must urgently counter Iran's ideological warfare and prepare for a shifting balance of power that diminishes American hegemony.

    The widespread operational embedding of AI in global supply chains creates significant systemic dependencies on shared digital infrastructure, raising novel aggregation risks for the insurance market. These risks are not limited to model failure but stem from common vulnerabilities—such as shared cloud platforms or flawed models—that could simultaneously impact multiple seemingly independent firms. Policy implications require both operators and insurers to shift focus toward managing these interconnected weaknesses by establishing robust controls, including mandatory human oversight, detailed audit trails, and staged deployments. Insurers must update underwriting practices to map systemic technology dependencies across policyholders rather than treating AI exposure as a standalone risk.
