Introduction: A World at a Legal Crossroads
In the space of barely two weeks in early 2026, the United States launched a joint military campaign against Iran without congressional authorisation, captured a sitting foreign head of state and transported him to American soil, and convened a handpicked coalition of Latin American nations at a private golf resort to sign a declaration pledging lethal military force against drug cartels. These are not the plot points of a geopolitical thriller – they are the documented, headline-grabbing events of the first quarter of a year that legal scholars are already describing as potentially the most consequential for the rules-based international order since 1945. This blog argues that 2026 represents not merely a period of geopolitical turbulence, but a deliberate, structural challenge to the architecture of international law – one in which the prohibition on the use of force, the doctrine of state sovereignty, and the constitutional limits on executive war powers are being simultaneously tested, reframed, and in some cases openly discarded.
The two events at the heart of this analysis: the Shield of the Americas initiative and Operation Epic Fury are connected not merely by their proximity in time but by the same underlying philosophy: that the United States reserves to itself the unilateral right to define threats and deploy lethal force in response, regardless of whether such actions are sanctioned by Congress, the United Nations Security Council, or the foundational norms of the UN Charter. Understanding why this matters requires both a clear-eyed account of what has happened and a sober assessment of what the international legal community may or may not be capable of doing about it.
The Shield of the Americas: A Monroe Doctrine for the Military Age
- What happened at Doral?
On March 7, 2026, President Donald Trump convened a summit at Trump National Doral Miami, gathering leaders from seventeen nations across the Western Hemisphere. The gathering, branded the ‘Shield of the Americas’, culminated in the signing of the Doral Charter – a proclamation establishing the Americas Counter-Cartel Coalition and committing member states to the use of lethal military force against transnational criminal organisations. Attendees included Argentina’s Javier Milei, El Salvador’s Nayib Bukele, Ecuador’s Daniel Noboa, and Chilean President-elect José Antonio Kast – a curated roster of ideologically aligned, right-leaning leaders who have embraced hardline positions on crime, migration, and state authority. Conspicuously absent were the region’s three largest economies: Brazil, Mexico, and Colombia.
The summit was not merely symbolic. Days earlier, on March 3, 2026, U.S. Special Forces had already deployed in Ecuador, advising and supporting Ecuadorian commandos in raids against drug trafficking organisations Los Choneros and Los Lobos groups the Trump administration had designated as Foreign Terrorist Organisations. Trump told assembled leaders at Doral that the United States stood ready to fire precision missiles at cartel leaders if partner nations simply identified the targets. ‘You want us to use a missile,’ he said. ‘They’re extremely accurate. Right into the living room. That’s the end of that cartel person.’ That a sitting U.S. president could offer precision airstrikes as a counter-narcotics service to foreign governments with apparently no legal framework governing such actions is a development whose gravity it is easy to underestimate.
- The Trump Corollary and the Monroe Doctrine Redux
The White House has explicitly framed the Shield of the Americas initiative as a ‘Trump Corollary’ to the Monroe Doctrine – the nineteenth-century policy by which the United States declared that European powers had no business intervening in the affairs of the Western Hemisphere. The Trump Corollary updates this logic for the twenty-first century: it is not European empires but Chinese economic encroachment, Iranian-linked militias, and narco-terrorist organisations that the United States now claims the right to neutralise, with or without the consent of the nations most directly affected. The administration’s 2025 National Security Strategy articulates an ‘enlist and expand’ approach, identifying ideologically compatible governments and deepening bilateral security arrangements that effectively subordinate regional sovereignty to American strategic objectives.
Critics have been pointed in their assessments. Scholars of inter-American relations noted that the original Summit of the Americas – a 34-nation multilateral forum built on consensus, inclusion, and carefully negotiated agendas was replaced by what one professor at the University of California, San Diego, described as a ‘hastily convened mini-summit’ that ‘conjures a crouched defensiveness, with only a dozen or so attendees huddled around a single dominant figure.’ The legal implications of the Doral Charter remain deeply ambiguous. Does a commitment to use ‘lethal military force’ against non-state actors within sovereign third-party states constitute a lawful collective security arrangement, or does it amount to an agreement to conduct what international law would ordinarily classify as unlawful armed interference in the domestic affairs of states like Mexico whose president was pointedly not invited and whose government has explicitly rejected U.S. military assistance?
Operation Epic Fury: War without Authorisation, Law without Enforcement
- The Strikes and Their Legal Context
On February 28, 2026, the United States and Israel launched nearly 900 joint military strikes against Iran in the first twelve hours of what the Pentagon designated Operation Epic Fury. The campaign targeted Iranian missiles and air defences, military infrastructure, leadership figures, and nuclear facilities. Iran’s Supreme Leader Ali Khamenei was killed in the opening salvos. More than 160 people perished when a strike hit a girls’ primary school adjacent to a naval facility in Minab. The Red Crescent later reported over 600 civilian deaths within days, with the Human Rights Activists in Iran citing an even higher toll. The strikes came just two days after Oman’s Foreign Minister had declared that a diplomatic breakthrough was ‘within reach’ a revelation that revealed the gap between the administration’s public posture and its private operational planning.
The legal vulnerabilities of Operation Epic Fury are numerous and, according to leading scholars, largely undeniable. Former Air Force Lt. Col. Rachel VanLandingham, who previously served as chief of international law at U.S. Central Command, stated plainly that the operation violated international law ‘in numerous respects’ as well as the U.S. Constitution and the 1973 War Powers Resolution. Under Article 2(4) of the UN Charter – the cornerstone of the post-1945 international legal order – the threat or use of force between states is prohibited except in cases of self-defence against an armed attack or with the authorisation of the UN Security Council. The Trump administration advanced no serious legal argument that either exception applied in this instance. The Centre for International Policy characterised the strikes as not an aberration but ‘the latest and most severe instance in a deliberate, escalating pattern’ of treating the prohibition on the use of force as optional.
- The Constitutional Dimension
Domestically, the constitutional controversy is equally acute. Article I of the U.S. Constitution vests in Congress the power to declare war – a provision that the framers placed in the legislature precisely because they feared the propensity of executive power to wage wars on personal or political impulse. The International Crisis Group described Trump’s unilateral launch of Operation Epic Fury as ‘a dramatic usurpation of Congress’s war powers even by the standards of recent decades of unilateral executive military action.’ Analysts at the Stimson Centre were blunter still, calling the operation ‘unconstitutional, unwise, and a betrayal’ of the president’s promise to prioritise the American people’s interests. Senator Tim Kaine introduced a joint resolution opposing the war, and Democratic members of Congress called on Speaker Johnson to reconvene the House to pass a War Powers Resolution though the measure faced uncertain prospects amid divided support.
The broader significance here is not simply one administration’s conduct but the gradual normalisation of an executive legal doctrine under which the president claims ‘vast discretion to use military force unilaterally to advance self-identified national interests,’ as the Crisis Group analysis put it. This doctrine has no endorsement from the courts or from Congress, yet it has accumulated power across successive administrations – Democrat and Republican alike through the precedent-setting effect of operations in Libya, Syria, and Yemen. Operation Epic Fury is best understood, in this light, as the most consequential expression to date of an executive war powers framework that has been quietly under construction for decades.
The Pattern: Venezuela, Maduro, and the Expanding Doctrine
Operation Epic Fury and the Shield of the Americas did not emerge from a vacuum. They are the latest expressions of a doctrine that began taking coherent shape in 2025. In September of that year, the United States conducted lethal strikes against vessels in the Caribbean, framing them as law enforcement operations – a legal sleight of hand designed specifically to avoid triggering the War Powers Resolution. In January 2026, U.S. forces conducted a military raid into Caracas, capturing then-Venezuelan President Nicolás Maduro and his wife and transporting them to the United States to face drug conspiracy charges. The administration publicly announced it would ‘run’ Venezuela until a new government was installed. The Centre for International Policy described this reframing of manifest armed force as a domestic law enforcement action as ‘not merely legally incorrect’ but ‘a deliberate attack on the conceptual architecture that makes international law legible.’
This sequence: Venezuela, Iran, Ecuador, and the institutionalisation of the cartel coalition reflects a coherent strategic logic, even if its legal foundations are fragile. The Trump administration is constructing, piece by piece, a new operational norm: that the United States, as the world’s pre-eminent military power, is accountable to no external legal authority in defining what constitutes a threat or what response is appropriate. The accumulation of these precedents matters enormously. Each action that goes unchallenged or that is challenged but ultimately tolerated makes the next action easier to justify and harder to condemn. The international community’s response to the Venezuelan raid set the table for the indifference that greeted the launch of Epic Fury; how the world responds to Epic Fury will shape whatever comes next.
What International Law says and why it is struggling to respond
- The UN Charter and Its Structural Limits
International law is not silent on the events of 2026. The UN Charter’s prohibition on the use of force is unambiguous, and the targeted killing of a head of state raises further questions under international humanitarian law, customary international law, and the Vienna Convention. The civilian deaths at Minab school engage the fundamental principles of distinction and proportionality under the laws of armed conflict. The capture and removal of Maduro from Venezuelan territory implicates the most basic norms of state sovereignty and the prohibition on forcible regime change that the international community has, at least in principle, upheld since the founding of the United Nations. Yet the international legal system’s structural limitations are nowhere more painfully apparent than in moments like these when the state most capable of breaching its norms is also the state whose cooperation is most indispensable to enforcing them.
- The Security Council Paralysis and the Erosion of Legitimacy
The UN Security Council, the body nominally charged with maintaining international peace and security, is structurally incapable of imposing consequences on the United States – a permanent member possessing veto power over any resolution seeking to censure, sanction, or mandate accountability for American military conduct. The same veto architecture that has long frustrated international response to Russian actions in Ukraine and Chinese activities in the South China Sea applies with equal force to American operations in Venezuela, Iran, or Ecuador. What changes is not the legal analysis but the political calculus: when one of the very powers that designed the international legal order uses its structural position to shield itself from accountability, it generates a crisis of legitimacy that no legal instrument alone can resolve.
The crisis is compounded by the reaction or rather, relative non-reaction of traditional U.S. allies. European governments, already navigating the strains of the post-NATO realignment and the ongoing war in Ukraine, have largely confined their responses to diplomatic statements of concern. The International Criminal Court lacks jurisdiction over the United States, which never ratified the Rome Statute. The International Court of Justice could potentially hear a state-to-state case, but enforcement of any ruling remains a political rather than legal question. What emerges from this picture is not a world in which international law has been abolished – it is a world in which international law is increasingly visible, increasingly invoked, and increasingly incapable of constraining the most powerful actors who choose to ignore it.
The Longer View: What gets rewritten, and who does the rewriting?
To ask whether 2026 is the year global law is rewritten is, in one sense, to ask the wrong question. Laws especially international laws, are rarely rewritten in any formal, explicit sense. They are eroded, reinterpreted, and eventually abandoned through accumulated practice, through the failure of enforcement, and through the construction of competing normative frameworks that, over time, come to carry more practical weight than the originals. What we are witnessing in 2026 is precisely this kind of incremental transformation, made more visible and more rapid by the scale and brazenness of the actions involved. The Shield of the Americas creates a precedent for military multilateralism that bypasses established inter-American legal and diplomatic institutions. Operation Epic Fury normalises pre-emptive war without congressional authorisation or UN sanction. The Maduro raid institutionalises the forcible seizure of foreign leaders as a law enforcement tool.
The question of who gets to do the rewriting matters enormously. If the United States can launch wars without congressional authorisation or UN sanction and face no meaningful legal or political consequence, then other powerful states Russia, China, India will draw their own conclusions about the enforceability of norms that were, in practice, always more honoured in the breach. The risk is not simply that American exceptionalism will go unchallenged in 2026; it is that the erosion of the rules-based order by its principal architect provides an irresistible justification for every other state that has ever found international law inconvenient. Legal scholars at the Centre for International Policy have argued that what is needed is a ‘dual-track approach’: constraint from within the United States through Congress and the courts, and constraint from without through sustained multilateral pressure and the development of new accountability mechanisms that do not depend on Security Council consensus.
There is also a deeper jurisprudential question worth raising in a blog aimed at legal readers. The doctrine of effectiveness in international law holds that a norm which is consistently and widely violated, without meaningful sanction, eventually loses its legal status – it ceases to be binding customary law and becomes merely aspirational language. Whether we are approaching that threshold with respect to the prohibition on the use of force, Article 2(4), the cornerstone of the UN Charter is not a question legal academics would have felt comfortable raising twenty years ago. In 2026, it is becoming unavoidable. The post-war legal order was built on the premise that no state, however powerful, was above the law. That premise is being tested in real time, and the verdict, as yet, is far from clear.
Conclusion: The Gavel is in the Air
The events of early 2026 do not represent the death of international law. They represent something in some ways more troubling: international law alive enough to be cited, quoted, and debated but not yet strong enough to restrain those with the greatest capacity for harm. The Shield of the Americas initiative and Operation Epic Fury are, at their core, exercises in norm contestation. They embody a view of international order in which security objectives, unilaterally defined, can supersede multilaterally agreed legal constraints. The legal community domestic and international has not been silent, and the breadth and quality of the legal criticism directed at these operations is itself evidence that the normative framework still matters to a significant portion of the global professional and scholarly community.
But critique, however incisive, is not constraint. Whether 2026 becomes the year that global law was rewritten or merely the year it was most severely tested will depend on whether domestic institutions in the United States, allied governments, international bodies, and civil society can mount a response proportionate to the challenge. The gavel of international accountability is in the air. Whether it falls and on whom remains the defining legal question of our moment. For those of us in the legal profession, watching from chambers and courtrooms and academic offices, the obligation is clear: to name what is happening, to insist on the standards, and to keep making the argument that law even imperfect, contested, and strained is better than no law at all.
