- Argentina blacklisted Iran’s Islamic Revolutionary Guard Corps in March following U.S. pressure on allies.
- Iran retaliated by designating Argentina’s navy and air force as terrorist groups.
- Buenos Aires cited the Guard’s backing of Hezbollah, which it blames for two deadly 1990s bombings.
- Iran acted under a 2019 law targeting nations that follow Trump’s original terror designation of the Guard.
- Argentina now faces Iranian reprisal for siding with Washington’s campaign.
In a diplomatic spat that shows how Washington's pressure campaign can drag faraway nations into Middle Eastern feuds, Iran's Foreign Ministry announced Wednesday that it has designated Argentina's navy and air force as terrorist groups. The decision, a direct tit-for-tat response to Buenos Aires' March blacklisting of Iran's Islamic Revolutionary Guard Corps, demonstrates how the Trump administration's push for allies to take tougher stances against Tehran is creating unexpected blowback for nations like Argentina on the other side of the globe.
Argentina's March decision followed U.S. pressure on allies
The drama began on March 31 when Argentine President Javier Milei, a staunch Trump ally, officially designated Iran's IRGC as a terrorist organization. That move came after weeks of pressure from the Trump administration for allied nations to take a harder line against Iran, particularly following the outbreak of the U.S.-Iran war in late February.
Buenos Aires justified its decision by pointing to the IRGC's support for Hezbollah, which Argentina blames for the 1994 bombing of the AMIA Jewish community center in Buenos Aires that left 85 people dead and injured hundreds more. That attack remains the deadliest terror attack in Argentina's history. Argentina also cited the 1992 bombing of the Israeli Embassy, an incident that killed 29 people. Iran has denied involvement in both cases.
Tehran responds under 2019 law allowing reciprocal designations
Iran's Foreign Ministry leaned on a 2019 law, passed after Washington blacklisted the IRGC, that allows payback against any country following America's lead. Citing the principle of reciprocity, the ministry said in a statement that Tehran now considers Argentina's air force and navy to be terrorist organizations. Notably, the designation did not extend to Argentina's army.
The ministry added that "the responsibility for all consequences arising from this matter will lie with the Argentine government," though it did not elaborate on what specific actions might follow. For now, the move seems to be largely symbolic, as Tehran did not attach any sanctions or penalties to the label.
Pattern mirrors recent actions against Western allies
Wednesday's move is part of an escalating pattern of reciprocal designations by Tehran. Less than two weeks before targeting Argentina, Iran slapped the same label on Britain's Royal Navy and Royal Air Force, retaliating for London's move in July to outlaw the IRGC using a new state-threats law. In February, Iran went after the navies and air forces of every EU member state not long after Brussels formally put the IRGC on its terror list, while Canada's navy was given the same treatment in December 2025. Each of these designations follows the same pattern: a U.S. ally moves against Tehran, and Iran responds by targeting that nation's military branches under its 2019 reciprocal law.
Argentina pays a price for siding with Washington
This latest diplomatic confrontation highlights an uncomfortable reality for nations that align themselves with Washington's aggressive posture toward Iran: once you pick a side, Tehran will not forget it. Argentina, a country separated from the Middle East by thousands of miles, now finds its military formally labeled as a terrorist entity by a major regional power after Buenos Aires answered a call from the White House.
The IRGC remains an elite force that answers directly to Iran's supreme leader and controls vast swaths of the Iranian economy, and the United States and European Union list it as a terrorist organization, while the UK has outlawed it as a national security threat. But for Argentina, the question now is whether this symbolic designation carries real-world consequences... and whether the benefits of standing with Washington were worth the risk of being dragged into a war that is not its own.
