Argentina Designates CJNG a Terrorist Organization: Milei’s Move and the Emerging Hemispheric Security Architecture
This Buenos Aires Times report covers the Milei government’s formal designation of Mexico’s Jalisco New Generation Cartel (CJNG) as a terrorist organization, adding it to Argentina’s Public Register of Persons and Entities Linked to Acts of Terrorism and their Financing (RePET).
The Argentine Presidency, Foreign Ministry, National Security Ministry, and SIDE intelligence secretariat coordinated the joint decision, which authorizes financial sanctions and operational restrictions targeting the cartel and its personnel. The designation mirrors the February 2025 US decision to classify the CJNG and six other transnational criminal organizations as foreign terrorist organizations, and Buenos Aires explicitly frames the move as a mechanism to strengthen multilateral security cooperation with aligned partner nations.
The article identifies the CJNG as a founding-2010 organization with confirmed presence in more than 40 countries, including Argentina, and as a principal supplier of fentanyl, methamphetamine, and cocaine to US markets. The article also notes that CJNG founder Nemesio “El Mencho” Oseguera was killed the previous month in a US-supported Mexican military operation, and situates the CJNG listing within a broader Milei-era pattern of terrorist designations that includes Hamas, Iran’s Quds Force, and branches of the Muslim Brotherhood.
El Centro’s Counter-Cartel Summit piece documents that a coalition of right-leaning Latin American governments—explicitly including Argentina—committed, alongside the United States at USSOUTHCOM, to employ military force against transnational criminal organizations, framing this alignment within the December 2025 National Security Strategy and the January 2026 National Defense Strategy. Meanwhile, the Criminal Governance piece’s analysis of FTO designations signals an emerging doctrinal reinterpretation of irregular warfare, one in which certain transnational criminal networks are recognized as coercive campaigners capable of shaping state behavior and eroding governance capacity in ways that generate strategically exploitable terrain amid great-power competition.
All of these assessments illuminate why Milei’s government treats the CJNG listing as simultaneously a domestic financial protection tool and a signal of geopolitical alignment with Washington: the designation is both a law enforcement instrument and a declaration of doctrinal solidarity within an emerging hemispheric security architecture.
