Why Iran’s strikes in response to U.S.–Israeli aggression are lawful selfdefense
TEHRAN – Iran has invoked its right to self-defense under Article 51 of the United Nations Charter following large-scale joint military strikes by the United States and Israel on its territory, asserting that its response is firmly grounded in international law and the principles governing the use of force between states.
According to the Iranian Red Crescent Society, nearly 800 people have been killed in the attacks, which struck military, and civilian areas. Iranian officials have described the strikes as unprovoked acts of aggression carried out without authorization from the United Nations Security Council, violating Article 2(4) of the UN Charter, which prohibits the use of force against the territorial integrity or political independence of any state.
While Iran has formally invoked Article 51 as the basis for its actions, international law analysts emphasize that the right of self-defense allows a state to respond not only to attacks on its territory but also to military forces and installations that are directly involved in the aggression, even if they are located abroad. This interpretation underlines the legitimacy of Iran’s strikes on U.S. military facilities in the Persian Gulf region, including bases in Qatar, Kuwait, Bahrain, and Iraq, which Iranian authorities contend were used to launch or facilitate the attacks on Iranian territory.
Legal experts note that under customary international law and the jurisprudence of the International Court of Justice, particularly the Nicaragua case, lawful self-defense must satisfy the principles of necessity and proportionality. Necessity requires that the defensive force be used to repel or prevent further attacks, while proportionality requires that the response remain limited to legitimate military objectives. Analysts argue that Iran’s retaliatory operations meet these criteria, as they were directed specifically at Israeli positions and U.S.-linked military facilities directly involved in the aggression, rather than civilian areas or the broader region.
Iranian officials have also pointed out that some host states had previously assured that their territories would not be used for attacks against Iran. Once U.S. bases in these countries were employed in the strikes on Iranian soil, analysts say they assumed the status of lawful military objectives, and Iran’s targeting of them falls within the framework of self-defense. Tehran insists that its measures were calibrated to deter further attacks rather than escalate the conflict unnecessarily.
Tehran has formally notified the UN of its actions, describing them as lawful, necessary, and proportionate defensive measures. Iranian authorities argue that the initial U.S.–Israeli strikes lacked any legal justification, as no Security Council mandate was obtained and no imminent threat from Iran against the United States or Israel was publicly demonstrated prior to the attacks.
Analysts further highlight that repeated U.S. and Israeli interventions, especially during the administration of U.S. President Donald Trump, normalized unilateral military operations outside the UN framework. From this perspective, Iran’s response is defensive: it is aimed at enforcing its sovereignty and deterring future aggression rather than seeking expansion or escalation.
Legal scholars stress that the right of self-defense is well-established in international law; the debate focuses on proportionality, necessity, and targeting. By striking only the military assets used in the aggression, Iran’s actions are consistent with both the UN Charter and customary international law.
As tensions rise, Tehran continues to frame its military response not as escalation but as enforcement of its lawful right to defend national sovereignty, ensuring that the initiators of force are held accountable while respecting the international legal framework. Analysts conclude that Iran’s actions, grounded in Article 51, underscore the distinction between lawful defensive measures and unlawful aggression, reaffirming the principles of state sovereignty and the rule of law in international relations.
