Argentina has expelled an Iranian diplomat and formally designated Iran's Islamic Revolutionary Guard Corps as a terrorist organization, marking the most significant deterioration in bilateral relations since the 1994 AMIA bombing that killed 85 people.
The dual measures, announced by the Foreign Ministry, represent a dramatic escalation in tensions between Buenos Aires and Tehran nearly three decades after the attack on the Argentine Israelite Mutual Association building that remains Latin America's deadliest terrorist incident.
President Javier Milei's administration cited "persistent Iranian non-cooperation" with international investigations into the AMIA bombing and recent intelligence assessments warning of continued Revolutionary Guard activities targeting Argentine Jewish institutions. The expelled diplomat, whose identity was not disclosed, has been given 72 hours to leave Argentine territory.
The designation places Argentina alongside the United States, Saudi Arabia, and Bahrain among nations that officially classify the Revolutionary Guard as a terrorist entity. The move grants Argentine authorities expanded powers to freeze assets, monitor financial transactions, and prosecute individuals with Guard connections operating within the country.
In Argentina, as across nations blessed and cursed by potential, the gap between what could be and what is defines the national psychology. The AMIA bombing epitomizes this frustrated promise. Despite multiple investigations, international arrest warrants, and decades of diplomatic pressure, not a single person has been convicted for the attack that devastated the heart of Buenos Aires' Jewish community.
Argentine prosecutors have long maintained that senior Iranian officials, including former intelligence minister Ahmad Vahidi and former Revolutionary Guard commander , who was killed in a drone strike in 2020, orchestrated the bombing through Lebanese Hezbollah operatives. has consistently denied involvement while refusing to extradite suspects named in Argentine and Interpol arrest warrants.
