In the early months of 2026, the world witnessed a definitive pivot in contemporary history. The geopolitical landscape of West Asia has undergone a fundamental shift, marked by Iran’s emergence as a proactive global maritime power—a transition that has effectively transformed foreign aggression into a strategic failure for the aggressors.
By exercising sovereignty over its territorial waters and invoking the inherent right of self-defence enshrined in Article 51 of the UN Charter, Iran has demonstrated its leverage over the world's most vital economic artery; the Strait of Hormuz. Crucially, this influence has thus far been manifested solely through a policy of non-provision of security for the waterway. Under international law, Iran maintains full sovereign rights over its territorial seas, possessing both the legal legitimacy and the military capacity to regulate or halt transit through the Strait.
This shift from active security provision to a negative security posture has elevated Iran from a regional player to a pivotal global actor—one capable of dictating the pulse of the world economy at will. In contemporary geopolitical theory, this is defined as “chokepoint power” (Farrell and Newman, 2019), a strategic asset that has proven more decisive in the 21st century than conventional or nuclear arsenals. Iran has underscored a singular reality. Global energy security and Iranian national security are two sides of the same coin. Any infringement upon Iran’s territorial integrity strikes directly at the economic stability of industrialised nations and global governance alike.
The costs imposed on the global economy following Iran’s defensive measures speak for themselves. In less than a month, Brent crude surged from approximately $70 to over $120 per barrel (UNESCAP, 2026). US and European stock markets plummeted by more than 10% (McPoland, 2026), while the United Nations warned that the ensuing disruption has pushed an additional 45 million people to the brink of acute hunger (United24 Media, 2026). These figures reflect the undeniable truth that the global economy can no longer afford to bypass Iran’s strategic interests.
In his inaugural public address, Ayatollah Sayyid Mojtaba Hosseini Khamenei, the Leader of the Islamic Republic, affirmed his commitment to the path of his martyred father. He stated that “the leverage to close the Strait of Hormuz must remain a primary tool for exerting pressure against our enemies” (Tabnak, 2026), reinforcing the centrality of Iranian management of the waterway.
The martyred Leader of the Islamic Revolution, Grand Ayatollah Khamenei (RIP), frequently highlighted the Strait's sensitive geopolitical standing. Throughout his leadership (1989–2025), he maintained that regional and global stability are inextricably linked to the security of Islamic Iran. He warned that any miscalculation by adversaries regarding the Iranian people's defensive capabilities would inevitably lead to a fundamental crisis in global energy security.
The following analysis will examine the geopolitical significance of the Strait of Hormuz, the legal basis for Iran’s management of the waterway, and the catastrophic consequences of instability resulting from illegal aggression by the US and Israeli regimes. Furthermore, it will address the legal and moral accountability of the aggressors for the resulting global turmoil.
The Legal and Strategic Foundations of Iran’s Maritime Power
In the framework of international law, a state’s sovereignty over its territorial waters remains one of the most fundamental principles enshrined in the 1982 UN Convention on the Law of the Sea (UNCLOS). The Strait of Hormuz—a strategic artery stretching 90 nautical miles in length and narrowing to just 21 miles at its throat—is divided between the territorial waters of Iran and Oman. What distinguishes this strait from other international waterways is a fact often obscured by misconception: Iran is a signatory to the Convention, having ratified it in 1996 (Better World Campaign, 2025). Consequently, as a coastal state, Iran exercises full sovereign rights over these waters, and all transit through this corridor is subject to the laws and regulations of the Islamic Republic.
Alongside this territorial sovereignty, Article 51 of the UN Charter recognises the “inherent right of individual or collective self-defence” for member states in the event of an “armed attack” (Security Council Report, 2025). The overt military aggression by the American and Israeli regims against Iranian soil in January and March 2026 constitutes a prima facie case of such an attack. These actions not only violated Article 2(4) of the UN Charter but directly targeted Iran’s territorial integrity and national sovereignty. Under customary international law and the jurisprudence of the International Court of Justice—notably the landmark ruling in Nicaragua v. United States (1986)—a state victimised by aggression is entitled to take proportionate and necessary countermeasures to halt such incursions and ensure its own security (Respicio, 2024).
Recent shifts in West Asia demonstrate that Iran has transitioned from a passive actor merely reacting to threats into a proactive power capable of reshaping the global economic calculus. The theory of “complex interdependence,” pioneered by Robert Keohane and Joseph Nye, elucidates the reality that in the modern world, dependency is rarely a one-way street (Blackwill, 2025). Just as the Iranian economy relies on oil revenues, the industrialised and emerging economies of the West and East are critically dependent on the safe, unhindered passage of oil, liquefied natural gas (LNG), and manufactured goods through the Strait of Hormuz.
