WASHINGTON, D.C. — The White House issued a stern ultimatum to Mexican criminal organizations on Tuesday, warning of a “swift and harsh” military response should American citizens be targeted in the violent wave of retaliation following the death of Nemesio “El Mencho” Oseguera Cervantes.
The warning comes as Mexico remains gripped by chaos. Since Sunday’s high-stakes military operation in Tapalpa, Jalisco, which resulted in the death of the Jalisco New Generation Cartel (CJNG) leader, the country has seen over 250 roadblocks, torched vehicles, and pitched battles between cartel gunmen and security forces across 20 states.
White House Press Secretary Karoline Leavitt confirmed that while the operation was executed by Mexican Special Forces, it was made possible through “critical intelligence support” provided by the United States. She emphasized that the Trump administration now views the CJNG not merely as a criminal enterprise, but as a foreign terrorist organization.
“Let the message be clear to those thinking they can strike at Americans or our interests in the wake of this operation,” Leavitt stated during a morning briefing. “Under President Trump’s leadership, any harm brought to U.S. citizens will be met with a response that is both immediate and overwhelming. We are no longer playing by the old rules of engagement.”
A Nation on Edge
The U.S. Embassy in Mexico City has maintained a “shelter-in-place” order for government personnel and citizens in high-risk zones, including Guadalajara, Puerto Vallarta, and Tijuana. The State Department has warned that the “decapitation” of the CJNG has created a volatile power vacuum, increasing the risk of collateral violence for tourists and residents alike.
In Mexico, President Claudia Sheinbaum has attempted to project a sense of returning order, claiming on Monday that “the country is at peace” and that most blockades had been cleared. However, the death toll tells a grimmer story: at least 25 members of the Mexican National Guard and dozens of cartel operatives have been confirmed killed in the last 48 hours.
Escalating Tensions
The elimination of “El Mencho,” a man with a $15 million U.S. bounty on his head, is being hailed in Washington as a landmark victory in the war on fentanyl. Yet, it also serves as a flashpoint for U.S.-Mexico relations. President Trump, taking to social media, urged Mexico to “step up” its efforts, reiterating his previous threats of direct military action on Mexican soil if the flow of drugs and violence does not subside.
The “Open Chronicle” has learned from senior administration sources that contingency plans for “kinetic options” are being reviewed should the cartels fulfill threats to target U.S. diplomatic or civilian hubs in retaliation for the intelligence sharing that led to El Mencho’s demise.
For now, thousands of American travelers remain stranded as flight disruptions continue across western Mexico. The White House maintains that while it seeks to respect Mexican sovereignty, the protection of American lives remains its “absolute and non-negotiable” priority.
