The fundamental norms of the United Nations Charter, particularly the prohibition on the use of force and the inviolability of state sovereignty, have been repeatedly challenged in the modern security landscape. The June 2025 military attacks by Israel, with direct support from the United States, on Iranian territory and its safeguarded nuclear facilities represent a critical juncture in this historical context, testing the resilience of the international legal order. This article aims to provide a comprehensive legal assessment of the legality of these actions under international law. Employing a doctrinal legal research methodology, the study conducts a systematic analysis of primary legal sources, including the UN Charter, ICJ jurisprudence, and non-proliferation treaties, integrated with secondary scholarly commentaries and institutional reports. Findings demonstrate that the attacks constitute a manifest act of aggression in violation of Article 2(4) of the UN Charter and the jus cogens rule prohibition on the use of force, as they were undertaken without Security Council authorization or a valid claim to self-defense under Article 51. Furthermore, the targeting of IAEA-safeguarded nuclear facilities breached the NPT and the Convention on the Physical Protection of Nuclear Material, eroding the global non-proliferation regime. The study also concludes that Iran’s defensive response was a legitimate exercise of its inherent right to self-defense. In conclusion, the attacks underscore a profound crisis in the UN collective security system, exacerbated by the Security Council's paralysis. The article ends with normative recommendations for upholding accountability and reinforcing the integrity of international law against unilateral militarism.
