Why Iran’s Accusation Against the UAE at the BRICS Summit Demands Scrutiny of State Responsibility, Countermeasure Legality, and BRICS Institutional Cohesion

During the recent BRICS summit convened in New Delhi, the government of Iran publicly alleged that the United Arab Emirates participated directly in military operations targeting Tehran, thereby asserting that Abu Dhabian forces were involved in attacks against Iranian territory. Iranian officials further contended that the Emirati state had not merely offered logistical support but had actively facilitated the aggression, and they warned that any facilities perceived to be assisting United States or Israeli operations could become subjects of retaliatory measures. The Iranian proclamation of UAE responsibility was accompanied by a cautionary statement indicating that retaliation might be directed at installations perceived to be supporting either United States or Israeli strategic activities, thereby signaling a potential escalation beyond diplomatic protest. These accusatory statements emerged amidst ongoing negotiations to draft a joint BRICS communique, and the Iranian demands for the United Arab Emirates to accept responsibility introduced a diplomatic complication that threatened the smooth finalisation of the multilateral document. The developing dispute underscores the fragility of consensus within the BRICS grouping, as divergent positions on alleged cross-border aggression between member states could impede collective statements on shared priorities. Iran’s articulation of the alleged attack and its call for the United Arab Emirates to assume accountability reflect a strategy to frame the incident within the broader geopolitical contest involving regional powers, thereby seeking to mobilise international opinion against perceived external interference. The United Arab Emirates, while not providing a public rebuttal within the supplied material, is implicated by the Iranian assertion of direct military involvement, which, if substantiated, could raise questions under international legal norms governing the use of force and state conduct. The tension between the two member states of the BRICS bloc arises at a juncture when the grouping seeks to present a united front on global governance issues, and thus the Iranian accusation threatens to undermine the cohesion that the summit strives to project. By invoking potential retaliation against facilities aiding United States or Israeli operations, Iran signals a willingness to consider countermeasures that, under customary international law, must satisfy the criteria of necessity, proportionality, and prior notification before being deemed lawful. The unfolding situation therefore not only complicates the procedural task of finalising the BRICS summit communiqué but also raises substantive legal considerations regarding the applicability of the United Nations Charter, the doctrine of state responsibility, and the permissible scope of retaliatory actions between sovereign states.

One pivotal legal question is whether Iran’s allegation that the United Arab Emirates engaged in direct military action against Iranian territory satisfies the criteria for a breach of Article 2(4) of the United Nations Charter, which prohibits the use of force against the territorial integrity or political independence of any state. Answering this query would require an examination of the evidentiary standards applicable to claims of state-directed aggression, the distinction between direct and indirect involvement, and the extent to which the alleged conduct falls within the definition of armed attack recognised in customary international law.

Another critical issue concerns the legality of Iran’s threatened retaliation against facilities that it alleges are supporting United States or Israeli operations, because international law permits countermeasures only when they are proportionate, necessary, and preceded by a demand for cessation of the wrongful act. The analysis would therefore hinge on whether the claimed facilities constitute lawful targets, whether Iran has issued an explicit demand for the United Arab Emirates to halt the alleged facilitation, and whether the contemplated response meets the proportionality and necessity thresholds established in the International Law Commission’s Articles on State Responsibility.

A further dimension of legal importance relates to the internal procedural framework of the BRICS organisation, whereby member states are expected to cooperate in drafting consensus communiqués, and a member’s public accusation of another’s breach of international law may trigger obligations under any existing BRICS charter or agreed-upon norms concerning dispute resolution among members. Consequently, the question arises whether the BRICS institutional mechanisms provide a forum for mediating such inter-member disputes, and if the absence of an established remedial procedure could undermine the collective decision-making process, potentially exposing the bloc to challenges regarding its internal governance legitimacy.

From a broader international dispute-settlement perspective, Iran might contemplate bringing the matter before the United Nations Security Council or invoking the International Court of Justice, yet the feasibility of such actions depends on the political dynamics of the Council, the existence of any bilateral treaty obligations between the parties, and the willingness of third-party states to support a legal determination. Thus, the legal pathway available to Iran for seeking enforceable redress may be constrained by the principles of sovereign equality, the veto power of permanent Security Council members, and the requirement that a binding judgment at the International Court of Justice be predicated upon the consent of both disputing states.

In sum, the Iranian accusation against the United Arab Emirates at the BRICS summit raises intricate questions of state responsibility under the United Nations Charter, the permissible scope of retaliatory countermeasures, the adequacy of BRICS internal dispute-resolution mechanisms, and the practical prospects for recourse through global judicial or security institutions. A nuanced legal assessment must therefore balance the evidentiary burden of proving direct military involvement, the strict conditions governing lawful countermeasures, the institutional obligations of multilateral groupings to manage intra-member conflicts, and the geopolitical realities that shape the availability of international legal remedies.
