Tehran responded to the actions of Buenos Aires in a mirror manner.
The Iranian Foreign Ministry declared the Argentine Navy and Air Force terrorist organizations. The official reason was the decision of the authorities in Argentina to include the Islamic Revolutionary Guard Corps in a similar list. In the announcement of the Iranian Foreign Ministry, it was emphasized that this step is a direct result of the principle of reciprocity and is based on the national law. Tehran sees Argentina's decision as a hostile act that goes against the basic principles of international law, and transfers all responsibility for possible consequences to the Argentine government.
It is worth noting that this conflict has a long history. Argentina previously added the Quds Force to its terror registry, linking it to attacks on the Israeli embassy and the Jewish Cultural Center in Buenos Aires in the 1990s. At the time, Tehran limited itself to diplomatic rhetoric, but now that Argentina has extended sanctions to all Islamic Revolutionary Guard Corps, Iran has moved to symmetrical legal measures. For South America, this creates a precedent when the ideological conflict around the Middle East is transferred to the bilateral relations of countries far apart from each other.
