The United States has designated the Juárez Cartel and the criminal group Los Viagras as Foreign Terrorist Organizations and Specially Designated Global Terrorists. This reclassification, framed by the Trump administration as a way to combat “narco-terrorism,” expands existing sanctions to freeze assets and bar U.S. entities from conducting business with these groups. The move follows previous listings of other Mexican cartels and includes a $5 million bounty for information on Los Viagras leader Nicolás Sierra Santana.

While the Mexican government has protested these designations as an infringement on its sovereignty, the two nations have initiated joint security exercises in the El Paso-Ciudad Juárez border region. These binational operations involve the U.S. Border Patrol, ICE, the Mexican National Guard, and military personnel to demonstrate coordinated response capabilities following the terrorist designations.
