English Summary

Analysis of post-1945 conflicts suggests that war is historically ineffective for achieving lasting security, wealth, or status, as states initiating conflict tend to fail their objectives. The primary driver for continued military action, however, is not material necessity but rather political miscalculation. Leaders often succumb to psychological biases and overconfidence, leading them to overestimate their chances of success despite available evidence of failure. This persistent desire among great powers for elevated status and prestige remains the most significant predictor of future conflict, regardless of the high costs involved.

中文摘要

對戰後1945年以來的衝突分析顯示,戰爭在實現持久安全、財富或地位方面,歷來是徒勞無功的。因為發起衝突的國家往往無法達成其既定目標。然而,持續進行軍事行動的主要驅動力,並非物質上的必要性,而是政治上的誤判。領導人常受心理偏差和過度自信的影響,導致他們即使面對失敗的證據,仍會高估自身成功的機率。這種大國對於提升地位和聲望的持續渴望,無論其代價多高,仍是預測未來衝突最關鍵的指標。

    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.
