English Summary

Robert Jervis's scholarship argues that in an anarchic international system, state cooperation is inherently difficult because foreign policies are frequently shaped by deep uncertainty, misperception, and psychological biases. Rooted in realist theory, his work emphasizes the challenge states face in accurately understanding one another's intentions and capabilities. Crucially, however, Jervis was not a pessimist; he maintained that political leaders possess the capacity to learn from historical mistakes and pursue enlightened self-interest. For policy strategists, this suggests that while misperception is constant, diplomatic efforts must focus on institutionalizing mechanisms for mutual understanding and promoting continuous learning among global actors.

中文摘要

羅伯特·傑維斯(Robert Jervis)的研究指出,在一個無政府的國際體系中,國家間的合作本質上極為困難,因為外國政策經常受到深度不確定性、誤判和心理偏見的影響。他的學說植根於現實主義理論,強調了各國在準確理解彼此意圖和能力方面所面臨的挑戰。然而,傑維斯並非悲觀論者;他主張政治領導人具備從歷史錯誤中學習的能力,並能夠追求開明的自身利益。對於政策戰略家而言,這意味著儘管誤判是常態,外交努力仍必須聚焦於建立制度化的機制來促進相互理解,並推動全球行為體之間的持續學習。

    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.
