When the West Says What the Arab World Already Knew: The Iran War and International Law

German President Frank-Walter Steinmeier called the war against Iran "völkerrechtswidrig" in March 2026. In Arab capitals, the reaction was not surprise but recognition. Legal scholars at Cairo University, the International Islamic University in Malaysia, and the Organisation of Islamic Cooperation had articulated the same legal assessment since the first strikes. The significance of Steinmeier's statement lies not in its novelty but in its origin: a sitting Western head of state validating a position the Global South has held from the outset.

This article examines the legal case as constructed from within Arab and Islamic legal scholarship, the institutional positioning of the Arab League and the OIC, and the structural reasons why Western and Arab legal communities arrived at the same conclusion through different analytical paths.

The Arab League and OIC: Institutional Responses

The League of Arab States convened an emergency session within days of the first strikes against Iran. The session produced a resolution condemning the military action as a violation of the UN Charter and calling for an immediate cessation of hostilities. The resolution passed with near-unanimity; only Bahrain abstained, reflecting its particular security alignment.

The Organisation of Islamic Cooperation, representing 57 member states, issued a parallel statement from its Jeddah headquarters. The OIC statement went further than the Arab League resolution, explicitly invoking Article 2(4) of the UN Charter and referencing the ICJ's jurisprudence on the use of force. The OIC also called for an emergency session of the UN General Assembly under the "Uniting for Peace" procedure.

These institutional responses were swift but unsurprising. Both organizations have a consistent record of opposing unilateral Western military action in Muslim-majority countries. What distinguished the Iran case was the degree of specificity in the legal argumentation. The OIC statement cited Nicaragua v. United States and the Oil Platforms case by name, signaling that the legal assessment was not merely political opposition dressed in legal language.

The Gulf Cooperation Council's position shifted dramatically after Iran retaliated against the initial US-Israeli strikes by hitting US bases and civilian infrastructure across Gulf states. Bahrain, Kuwait, Qatar, the UAE, Oman, and Jordan all suffered Iranian strikes. The GCC co-sponsored UN Security Council Resolution 2817 (2026), which condemned Iran's "egregious attacks" against neighbors and was adopted 13-0-2, with 135 co-sponsoring states. Saudi Arabia and the UAE, both of which have their own security concerns about Iran's regional influence and nuclear ambitions, found themselves in the paradoxical position of condemning both the initial Western strikes and Iran's retaliatory attacks on their soil.

Arab Legal Scholarship: A Different Starting Point

Western legal debate on the Iran war has centered on whether Article 51 self-defense can be stretched to cover anticipatory or preventive action against a nuclear-threshold state. The question is framed as a tension between the Charter's text and evolving security realities.

Arab legal scholarship begins from a different premise. Scholars at institutions including Al-Azhar University, the University of Jordan Faculty of Law, and the Qatar Faculty of Islamic Studies have emphasized that the prohibition of force in the UN Charter is not merely a technical rule but reflects a fundamental principle of sovereign equality. The history of Western military intervention in the Middle East, from Suez 1956 through Iraq 2003 to Libya 2011, provides the interpretive backdrop against which Arab legal scholars read Article 2(4).

Ahmed Abou El Wafa, professor of international law at Cairo University and a member of the Institut de Droit International, has argued that the pattern of Western states invoking self-defense to justify military operations in Muslim-majority countries has eroded the credibility of Article 51 as a legal norm. In his assessment, the Iran strikes represent not a novel legal question but the continuation of a pattern in which self-defense serves as legal cover for strategic objectives.

Mohammed Bedjaoui, the Algerian jurist and former president of the ICJ, argued throughout his career that the Charter's prohibition on the use of force must be interpreted with particular attention to the interests of developing nations, which bear the disproportionate burden of military interventions. His intellectual legacy shapes how a generation of Arab and African legal scholars approach cases like the Iran war.

This perspective does not produce a different legal conclusion. Western and Arab scholars largely agree that the strikes lack sufficient legal basis. But the analytical framework differs: where Western scholars ask whether the law permits an exception, Arab scholars ask why exceptions always seem to apply in one direction.

Islamic Law and the Prohibition of Aggression

Islamic legal tradition (fiqh) contains its own framework for evaluating the legitimacy of armed conflict. While international law and Islamic law operate in separate normative systems, their intersection matters in the political discourse of Muslim-majority states and within the OIC.

Classical Islamic jurisprudence distinguishes between defensive jihad (responding to aggression against Muslim lands) and offensive jihad (a concept whose modern applicability is rejected by the majority of contemporary Muslim legal scholars). The Quran states: "Fight in the way of God those who fight you, but do not transgress. Indeed, God does not love transgressors" (2:190). This verse is widely cited by contemporary Muslim scholars as establishing a prohibition of aggression that parallels Article 2(4).

The Islamic Fiqh Academy, operating under the OIC, issued a resolution in 2026 stating that the military strikes against Iran constitute aggression ("udwan") under both international law and Islamic legal principles. The resolution referenced both the UN Charter and Quranic injunctions against transgression.

This dual-framework approach carries political significance in Muslim-majority countries. It allows governments and civil society to oppose the war on both secular international law grounds and religious legal grounds simultaneously, broadening the coalition of opposition.

The Hypocrisy Gap

Steinmeier's statement was welcomed across the Arab world, but it also highlighted what commentators in the region describe as European hypocrisy. Germany calls the war illegal while the US Air Force coordinates Middle East operations through Ramstein Air Base on German soil. European nations express concern about civilian casualties while continuing arms sales to parties involved in the conflict.

The Al Jazeera Arabic editorial board noted in a March 2026 commentary that Steinmeier's words would carry more weight if accompanied by concrete action: denying overflight rights, suspending military cooperation, or initiating proceedings at the ICJ. Without such steps, the legal assessment remains, in their framing, a statement of fact without consequences.

This critique resonates beyond media commentary. The Arab League resolution explicitly called on European states that have characterized the war as illegal to "align their actions with their legal assessments." The gap between verbal condemnation and material facilitation is a central theme in how the MENA region processes European responses to the conflict.

Egyptian legal scholar Nabil Elaraby, former secretary-general of the Arab League and former ICJ judge, observed in a widely cited interview that international law's credibility in the Global South depends not on the correctness of legal analysis but on whether legal conclusions produce equal consequences regardless of who violates them. When Iraq invaded Kuwait in 1990, the Security Council authorized force within months. When Western states initiate military operations without authorization, the enforcement mechanisms are absent.

The Security Council's Selective Action

The UN Security Council's handling of the Iran war illustrates a pattern that MENA states have observed repeatedly. The Council adopted Resolution 2817 (2026), condemning Iran's retaliatory strikes on Gulf neighbors, by a vote of 13 in favor to none against, with Russia and China abstaining. The resolution passed with extraordinary support: 135 states co-sponsored it. But a separate Russian-drafted resolution calling on all parties to cease military activities was rejected by a vote of 4 in favor to 2 against, with 9 abstentions. The US voted against the ceasefire draft.

For Arab states, this asymmetry is the story. The Council could muster near-unanimity to condemn Iran's retaliatory strikes but could not agree to demand that all parties stop fighting. The initial US-Israeli strikes that triggered the entire chain of escalation were not addressed in any adopted resolution.

The "Uniting for Peace" mechanism, invoked by the OIC, allows the General Assembly to recommend collective measures when the Security Council is deadlocked. General Assembly resolutions lack binding legal force. They carry political and moral weight but cannot compel compliance.

This structural dynamic is well understood in the Arab world, where it is cited as evidence that the international legal order operates on a two-tier system: binding rules for the weak, optional guidelines for the powerful. The Security Council's failure to act on the Israeli-Palestinian conflict, the Syrian civil war, and now its selective action on the Iran war reinforces this perception. Whether or not the characterization is fair as a matter of legal theory, it shapes how the Iran war's legality is discussed in the region.

What Arab Capitals Are Watching

Beyond the legal frameworks, MENA governments are assessing the practical implications of the precedent being set. If military strikes against a nuclear-threshold state are accepted as legal under an expanded reading of self-defense, the implications extend far beyond Iran.

Several Arab states operate civilian nuclear programs or have announced nuclear energy ambitions, including Saudi Arabia, the UAE, Egypt, and Jordan. The precedent that nuclear enrichment capability, even short of weaponization, can trigger military strikes raises security concerns across the region.

The UAE, which operates the Barakah nuclear power plant, has been particularly attentive to the legal framing. While the UAE's program is transparently civilian and under full IAEA safeguards, the principle that a state's nuclear activities could be cited as justification for military action creates uncertainty.

Turkey, straddling Europe and the Middle East, has maintained a carefully calibrated position. Ankara condemned the strikes as disproportionate without using the term "illegal," reflecting Turkey's complex relationship with both the Western alliance and its regional interests.

The legal debate over the Iran war is, for MENA states, not an academic exercise. It is a live question about the rules that govern their security environment and whether those rules apply equally to all.
