U.S. President Donald Trump declared that American forces are ready to start ground war operations targeting drug cartels within Mexican territory, a startling escalation of Washington’s campaign against transnational crime that has caused a stir in diplomatic circles throughout the Americas.
“We are going to start now hitting land with regard to the cartels,” declared President Trump, claiming that the cartels control Mexico. However, he did not provide any operational details or a timeline.
The president’s remarks are in line with his larger plan to disrupt drug trafficking networks, which he has identified as serious threats to U.S. national security, and they come after the recent U.S. military action in Venezuela, where forces apprehended the country’s overthrown leader. 
Legal and diplomatic experts warn that unilateral military operations on Mexican territory—one of the United States’ closest allies and largest trading partners—would be against international law without Mexico’s consent.
Such “ground war” actions may also raise constitutional concerns regarding executive war powers in the absence of clear authorization from Congress.
President Claudia’s administration in Mexico has vehemently rejected the idea of American forces operating inside its borders, insisted that any cooperation respect Mexican sovereignty, and continuously opposed foreign military presence on Mexican soil. Despite her opposition to direct intervention, she has also advocated for increased security coordination.
The Sinaloa Cartel and the Jalisco New Generation Cartel, the two most potent criminal groups in Mexico, control a large area and have been connected to tens of thousands of violent deaths.
Although Mexico denounced the decision as a threat to national sovereignty, Trump’s earlier 2025 designation of several cartels as foreign terrorist organizations caused controversy and raised the possibility of increased U.S. operations.
It is currently unclear how formal bilateral agreements might influence the next stage of the U.S. anti-cartel strategy, as well as whether the administration will seek Congressional approval for increased military action.
