Congress has significantly expanded presidential tariff authority by passing the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, allowing the executive to impose up to 100% tariffs on key buyers of Russian energy and sanctions enablers. The article argues that this legislation represents a dangerous abdication of Congress's Article I authority, as it grants the executive vast, discretionary power without specifying criteria for enforcement. Historically, the executive could claim tariffs were its own doing; however, by writing and passing this new authority, Congress now owns the resulting trade policy and its economic consequences. This shift implies that future tariffs will be viewed by the public as a direct legislative action, potentially undermining the administration's credibility and creating political vulnerability.
Global trade 2026
English Summary
Chatham House argues that global trade is entering a structurally unstable phase in which economic security, geopolitical rivalry, and nationalism increasingly override traditional free-trade norms. The conference framing points to major drivers: a reoriented US trade posture under the second Trump administration, mounting pressure on the WTO and rules-based system, securitized supply chains, and intensified competition over technology and critical materials. It also highlights uneven regional adaptation, with Asian economies seeking growth opportunities while European governments struggle to balance competitiveness, resilience, and domestic political pressures. The strategic implication is that governments and firms should prioritize risk management, supply-chain resilience, and coalition-based rule-setting, while preparing for deeper fragmentation if multilateral mechanisms continue to weaken.
中文摘要
查塔姆研究所（Chatham House）指出，全球貿易正進入一個結構性不穩定階段，經濟安全、地緣政治競爭與民族主義日益凌駕於傳統自由貿易規範之上。該會議的分析框架指出了主要驅動因素：第二屆川普政府下美國貿易立場的重新定向、世界貿易組織（WTO）與規則導向體系所承受的壓力升高、供應鏈安全化，以及圍繞科技與關鍵原材料的競爭加劇。報告亦強調區域調適的不均衡：亞洲經濟體積極尋求成長機會，而歐洲各國政府則在競爭力、韌性與國內政治壓力之間艱難權衡。其戰略意涵在於，政府與企業應優先強化風險管理、供應鏈韌性與以聯盟為基礎的規則制定能力，並在多邊機制持續弱化的情況下，為更深層的碎片化預作準備。

Cuba is on a trajectory toward an accelerating state and economic collapse, risking a point of no return. The state is deteriorating into "authoritarian anarchy," retaining its capacity for political repression but losing the ability to provide basic public services like health and safety. Economically, while the private sector is growing, this expansion is highly unequal, fueling cronyism and widening class gaps between the elite and the poor. If the current trend continues, the country risks calcifying these defects into a dysfunctional baseline, severely diminishing the chances of a stable, democratic transition.

The article argues that China's ongoing purges are not signs of weakness, but rather a sophisticated, historically rooted process of 'rectification' that strengthens the CCP's grip on power. This mechanism requires cadres to submit mandatory self-criticisms and build permanent, detailed personnel files (dossiers). This system of record-keeping is the CCP's primary source of resilience, creating profound, internalized discipline that controls internal dissent. Policymakers must recognize that the regime's durability stems from this deep internal control mechanism, making succession—rather than internal purges—the ultimate strategic vulnerability.

The analysis argues that contemporary warfare is marked by a return to great power competition, often fueled by strategic hubris and historical overconfidence. A key failure across modern conflicts is the 'short-war fallacy'—the assumption that overwhelming military force guarantees a quick, decisive victory. This mindset blinds policymakers to the need for sustained resource mobilization and complex political outcomes. Consequently, effective strategy requires linking military objectives with clear, comprehensive political goals, rather than pursuing rapid, decisive regime changes or military victories in isolation.

The report argues that the rapid integration of AI creates novel and complex risks—such as deepfakes, misinformation, and intellectual property disputes—that do not fit within existing insurance lines, challenging the technology's overall insurability. Evidence shows that while lawsuits center on IP, the scope of harm is expanding into privacy and product liability, and insurers are responding unevenly with a mix of exclusions and limited coverage. Policymakers must therefore focus on managing systemic, correlated AI risks, including shared model dependencies and universal attacks, to prevent market failure and guide necessary regulatory oversight.
