The emerging conflict in the Persian Gulf has evolved into a confrontation between the formidable conventional military capabilities of the United States and Israel on one side and the government of Iran on the other. The Iranian strategy reportedly focuses on disrupting maritime oil shipments and destabilising the global economy by threatening critical shipping corridors such as the Strait of Hormuz. This confrontation represents not only a military contest but also a legal and economic struggle over the control of maritime routes that sustain the global energy system. The Persian Gulf remains one of the most significant regions in the international trading network because a large share of the world’s petroleum exports travels through its narrow waterways. Any attempt to obstruct shipping routes, therefore, raises profound legal questions concerning maritime law, the regulation of armed conflic,t and the protection of global commerce. From the perspective of international law and global governance, the conflict highlights the vulnerability of strategic maritime corridors when geopolitical tensions escalate into open confrontation.
Legal status of the Persian Gulf shipping lanes
The Persian Gulf contains several waterways that fall under the legal classification of international straits used for navigation between bodies of high seas. The legal framework governing these routes derives largely from the United Nations Convention on the Law of the Sea. Under this legal regime, ships from all nations possess the right of transit passage through international straits. This principle guarantees that vessels may navigate through these corridors without obstruction, provided their passage remains continuous and does not threaten the security of coastal states. The Strait of Hormuz represents the most critical example of such a waterway. Iran controls the northern coastline while Oman occupies the southern side. Although both states exercise sovereignty over their territorial seas, international law limits their ability to impede maritime traffic. If hostilities result in the obstruction of shipping lanes through mine deployment or naval attacks, the situation could constitute a challenge to the principle of freedom of navigation that underpins global maritime law.
Iranian asymmetric strategy and the law of naval warfare
Iran’s military doctrine has long emphasised asymmetric tactics designed to offset the technological superiority of conventional military forces such as those fielded by the United States and Israel. These strategies often include the use of sea mines, anti-ship missiles, and fast attack craft capable of operating in confined maritime environments. International humanitarian law does not entirely prohibit naval mines or other maritime weapons, but it regulates their use through the principles governing armed conflict at sea. These rules require belligerent states to direct attacks only against legitimate military objectives and to avoid actions that create disproportionate harm to civilian shipping. Deploying mines in heavily trafficked shipping lanes such as the Strait of Hormuz would raise serious legal concerns because commercial vessels transporting energy resources represent civilian objects under international law. Even if such tactics provide strategic leverage against adversaries, their use must comply with the principle of proportionality.
The prohibition on the use of force and collective self-defence
The broader legality of the conflict must also be evaluated within the framework of the United Nations Charter. Article two of the Charter prohibits the use of force against the territorial integrity or political independence of any state except under limited circumstances. States may lawfully resort to military force if they are acting in self-defence in response to an armed attack or under authorisation from the United Nations Security Council. In practice, determining whether these conditions have been satisfied often becomes the central issue in international legal debates concerning armed conflict. The involvement of Israel alongside the United States could be interpreted as an example of collective self-defence if both states argue that Iranian actions constitute a direct threat to their security interests. Such claims would inevitably face scrutiny from international legal scholars examining whether the threshold for lawful defensive action has been satisfied.
Economic warfare and global energy security
Beyond the legal framework governing armed conflict, the Persian Gulf confrontation illustrates how economic warfare can influence geopolitical strategy. By threatening oil shipments, Iran may seek to exert pressure on global markets and compel international actors to intervene diplomatically. Energy supply disruptions in the Gulf have historically triggered immediate volatility in global oil prices. Because many economies rely heavily on petroleum imported from the region, even temporary interruptions in shipping can produce widespread economic consequences. International energy markets, therefore, respond quickly to military developments affecting Gulf shipping routes. Insurance costs for tanker vessels often increase sharply during periods of heightened risk, while energy traders adjust supply forecasts based on geopolitical developments. The strategic significance of these economic consequences ensures that maritime security in the Gulf remains a matter of global concern rather than a purely regional issue.
Strategic imbalance and escalation risks
The military imbalance between the conventional forces of the United States and Israel and the Iranian armed forces does not necessarily translate into strategic simplicity. Asymmetric tactics can enable smaller powers to disrupt larger military forces by targeting critical vulnerabilities such as supply routes and logistical infrastructure. The narrow geography of the Strait of Hormuz provides an environment where relatively small naval forces can influence the movement of much larger fleets. This geographic reality has long shaped the strategic calculations of both regional and global military planners. Escalation in such an environment could rapidly expand beyond initial military objectives and produce unintended consequences affecting global trade and diplomatic relations.
International law and the protection of global commons
The conflict ultimately highlights a broader legal principle concerning the protection of global commons. Strategic maritime corridors such as the Persian Gulf function as shared infrastructure upon which the international economy depends. International law attempts to preserve these routes through rules designed to guarantee freedom of navigation and limit the disruption of civilian commerce during armed conflict. Yet the effectiveness of these rules depends heavily on the willingness of states to respect them even during periods of intense geopolitical rivalry. The unfolding confrontation, therefore, represents not only a military struggle but also a critical test of the resilience of the international legal order in safeguarding the stability of global trade.
