Mexico Bolsters Sovereignty Through Constitutional Reform After U.S. Terrorism Designations

Mexico’s Chamber of Deputies approved crucial constitutional amendments with 327 votes supporting, 116 opposing, and zero abstentions. The reforms strengthen national sovereignty and target illegal arms trafficking after recent US actions.

President Claudia Sheinbaum proposed these changes in direct response to the United States designating eight criminal organizations as foreign terrorist organizations.

The list includes the Sinaloa Cartel, Jalisco New Generation Cartel, Cárteles Unidos, Northeast Cartel, Gulf Cartel, La Nueva Familia Michoacana, Tren de Aragua, and Mara Salvatrucha.

Many Mexican officials fear these designations could potentially justify US military intervention on Mexican soil. Trump previously suggested such action during his presidential campaign earlier this year.

The constitutional reform modifies two key articles. Article 19 now adds terrorism to crimes requiring mandatory preventive detention. It also extends severe penalties to nationals and foreigners involved in illegal weapons trafficking or activities threatening Mexican sovereignty.

Article 40 explicitly prohibits foreign interventions, interference, coups, election meddling, and territorial violations. The text asserts that Mexicans “will not accept under any circumstances interventions or interference from abroad.”

Mexico’s Stance on US Terrorism Designations and Sovereignty

Sheinbaum emphasized the unilateral nature of US terrorism designations. “What we want to make clear is that we do not negotiate sovereignty,” she stated during a press conference.

The amendments specifically target the flow of US-manufactured firearms into Mexico. Official data shows between 70% and 90% of weapons recovered at Mexican crime scenes originate from the United States.

Recent tensions escalated after reports revealed US deployment of MQ-9 Reaper drones in Mexican airspace without notification to Mexican authorities. Defense Secretary Ricardo Trevilla expressed concerns about these sovereignty violations.

For implementation, the constitutional changes require approval from at least 17 of Mexico’s 32 state legislatures. This reform joins twelve other constitutional amendments passed since Sheinbaum took office in October 2024.

Sheinbaum maintains Mexico welcomes coordination with the US on security matters but rejects subordination. “This cannot be an opportunity for the United States to invade our sovereignty,” she declared.
