- Internal Distractions Mexico's armed forces are overwhelmingly tethered to domestic anti-cartel operations, severely capping any external force projection capabilities.
- Cyber Vulnerabilities Mexico's recognized structural lag in cybersecurity could be actively exploited by Argentina's advanced domestic technological sectors (INVAP) to disrupt command and control.
