How the Revealed US Plan to Extract Iran’s Enriched Uranium Raises Complex Issues of International Law and State Responsibility

Former President Donald Trump disclosed that a previously contemplated operation to physically remove Iran’s enriched uranium through military means had been abandoned because he judged the undertaking to involve excessive risk, and he further asserted that the United States possessed the capability to seize the nuclear material, describing it as being stored in a condition he termed entombed and therefore secure from external interference; according to the statement, United States diplomatic representatives engaged in consultations with technical specialists in preparation for forthcoming nuclear negotiations with the Iranian government in Tehran, and these consultations occurred despite the existence of significant divergences among the United States negotiating team members regarding the strategic direction and procedural approach to be adopted in the upcoming talks, while the overall depiction presented by the former president combines an admission of a shelved military option, a claim of latent capability, and an ongoing diplomatic effort that together underscore the complexity of the United States’ policy considerations concerning Iran’s nuclear programme.

One question is whether a planned military operation to extract enriched uranium from Iranian territory would be permissible under the customary international law principles governing the use of force, and the answer may depend on whether such an operation could be justified as an act of self‑defence, a necessity to prevent imminent nuclear proliferation, or a lawful enforcement of United Nations Security Council resolutions pertaining to Iran’s nuclear activities; perhaps the more important legal issue is whether the existence of a credible threat posed by the material could satisfy the extraordinary threshold required for pre‑emptive self‑defence under the Caroline test, which traditionally demands an imminent and overwhelming danger.

Another possible view is that the operation would violate the prohibition on the use of force enshrined in Article 2(4) of the United Nations Charter, which obliges all Member States to refrain from threatening or employing force against the territorial integrity or political independence of another State, unless authorized by the Security Council or justified by self‑defence, and perhaps the procedural significance lies in the requirement that any Security Council resolution authorising such a measure must be adopted under Chapter VII, providing a clear legal basis that would otherwise be absent in a unilateral action.

A further legal question concerns the applicability of the Treaty on the Non‑Proliferation of Nuclear Weapons, which obliges non‑nuclear‑weapon States to pursue nuclear disarmament and for nuclear‑weapon States to prevent the spread of nuclear weapons; extracting enriched uranium without Iran’s consent could be interpreted as a breach of the treaty’s safeguard provisions and may trigger counter‑measures, and perhaps the more important issue is whether the alleged extraction would be deemed a violation of Iran’s sovereign rights under customary international law, thereby giving rise to a right of state responsibility and the entitlement to reparations or other remedial measures.

Another possible view is that the diplomatic consultations described as involving United States envoys and technical specialists create expectations under the principle of good faith in international negotiations, yet they do not, by themselves, generate legally enforceable obligations unless crystallised into a formal treaty or agreement, a nuance that may affect any subsequent dispute resolution mechanisms, and perhaps the legal position would turn on whether any statements made during those consultations could be characterised as unilateral declarations that, under international law, might acquire legal effect if they meet the criteria of clarity, specificity and intention to be bound.

Perhaps the legal position would turn on whether Iran could invoke jurisdiction of the International Court of Justice or petition the United Nations General Assembly for a resolution condemning the threatened extraction, given that both parties are State actors bound by the UN Charter, and whether any provisional measures could be sought to preserve the status quo pending resolution of the substantive legal issues, and another possible view is that even in the absence of an existing treaty dispute, Iran might pursue a claim of illegal use of force before the International Court of Justice, invoking the principle that any breach of the prohibition on force entails a violation of international obligations, thereby opening the door to adjudication and possible remedies.
