Argentina Declares Iranian Charge d'Affaires Persona Non Grata

The government of Javier Milei resolved on Wednesday, April 2, 2026, to take a step of maximum diplomatic hardness and declared the chargé d'affaires of the Embassy of Iran in Argentina, Mohsen Soltani Tehrani, persona non grata, ordering him to leave the country within a 48-hour period. The decision, communicated by the Ministry of Foreign Affairs, International Trade and Culture led by Pablo Quirno, abruptly raised tension with Tehran and left the bilateral relationship at one of its most delicate moments in recent years. The measure came as a direct response to the harsh pronouncement of the Iranian regime against the Argentine decision to declare the Islamic Revolutionary Guard Corps a terrorist organization. In the government, they interpret that it was not just a diplomatic disagreement, but a direct affront from a state that, furthermore, drags a persistent refusal to collaborate with the Argentine Justice in the AMIA case and to comply with the Red Notices of Interpol regarding several of the accused. In this context, the expulsion of Mohsen Soltani Tehrani also has strong internal political value. In an increasingly tense international scenario, the expulsion of the main Iranian diplomat in Buenos Aires marks a point of no return in a relationship that carried deep wounds and, as of this Thursday, entered an openly confrontational phase. In the reading of the Casa Rosada, the Iranian reaction was not a simple diplomatic protest but a new attempt to politically pressure a country that, under the current administration, resolved to harden its stance against international terrorism and against the actors that the Argentine Justice links to the attacks that struck the country in the nineties. The background of the conflict is not minor. The decision also deepens the international alignment of Milei with the United States and Israel, a line that the Casa Rosada had already been exhibiting in foreign policy matters, but which now translates into a concrete measure of extremely high institutional and symbolic impact. The resolution also reopens a fundamental discussion about Argentine policy towards Iran. The regime qualified the Argentine measure as illegal, improper, and functional to the interests of the United States and Israel, and even went so far as to warn of possible consequences on the bilateral and international plane. Just two days before, the Office of the President informed that Argentina had incorporated the Islamic Revolutionary Guard Corps into the registry of terrorist organizations, a political and juridical definition of enormous weight that the Government linked to the advances in the investigations of the attack against the AMIA and the attack on the Embassy of Israel in Buenos Aires. It was that tone that ended up triggering the reaction of the Argentine Chancellery, which decided to expel the main Iranian representative in the country. The libertarian administration seeks to transmit that it will not tolerate intimidations or speeches from a regime that it holds, together with Hezbollah, responsible for the two largest terrorist attacks suffered on Argentine soil. Now, the Government bets on breaking with that logic and showing itself in a position of open confrontation before a regime that it considers hostile, covering up, and alien to any real will of judicial cooperation. According to the official argument, those judicial files and intelligence works allowed to sustain that there was the participation of high-ranking officials of the Iranian regime and of operatives linked to that structure. In that key, the expulsion of the Iranian head of mission does not appear as an isolated episode, but as part of a broader sequence: classification of the Revolutionary Guard as a terrorist organization, vindication of the memory of the victims, and political sign that the relationship with Tehran will no longer be administered with the caution that predominated in other periods. It remains to be seen now what will be the response of Iran and to what extent this new crisis will escalate. But in Argentina, the official signal was already sent with all firmness. Milei decided to tense the rope with a regime that he accuses of having systematically failed to comply with its international obligations and having hindered for decades the advance of the truth and justice. For years, the relationship was traversed by judicial advances, diplomatic setbacks, ambiguous gestures, and stages of frank paralysis. From the Chancellery, they maintained that the communiqué issued by Iran contained “false, offensive, and improper accusations” against the Argentine Republic and its highest authorities, in addition to constituting an unacceptable interference in internal affairs. With that decision, the Milei administration sought to show a line of action without nuances before an organization considered central in the scaffolding of regional projection of the Iranian power. The response of Tehran was immediate and loaded with virulence.
