Fighting the cartels goes international
Trump’s National Security Strategy is bearing fruit in the Western Hemisphere.

Secretary of War Pete Hegseth stepped away from overseeing Operation Epic Fury to host the hemispheric defense conference, where the focus was forging a more unified regional security strategy with neighboring nations. In his March 5, 2026 remarks at the Americas Counter Cartel Conference (A3C) in Doral, Florida, Hegseth emphasized plans to expand bilateral and multilateral cooperation to coordinate military operations, security partnerships, and contingency response across the region overseen by the United States Southern Command (SOUTHCOM) which is also headquartered in Doral. Notably, just days before the conference, the United States and Ecuador engaged in their first joint military ground operation against South American drug cartels, the very kind of coordinated action Hegseth urged in his remarks.
Hegseth described a kind of “neighborhood watch” writ large, where sovereign nations work to “prevent external powers from threatening our peace and independence in our shared neighborhood,” expressly recalling the Monroe Doctrine framework and referring to it as the Trump Corollary of the Monroe Doctrine, while jokingly calling it the “Donroe Doctrine.”
Representatives from 17 countries attended the conference, which was described as the first gathering of its kind “in more than 30 years.” The participating leaders signed the Joint Security Declaration, a foundational document committing their governments to deeper cooperation on border security, countering narco-terrorism, trafficking, addressing other shared threats, and protecting critical infrastructure across the Western Hemisphere.
Consistent with Trump’s National Security Strategy (NSS) and the administration’s designation of cartels as terrorist organizations, Hegseth cast cartels and narco-terrorism as military threats, not simply law enforcement challenges. His remarks echoed secretary of State Marco Rubio’s Feb. 14, 2026 address at the Munich Security Conference (MSC), but with a sharper emphasis America’s own hemisphere. Under the Trump administration, regional leaders, Hegseth said will no longer “accept the status quo to co-exist with narco-terrorism or [rely solely on a] law enforcement-alone approach that [has] failed to deter and dismantle threats.” He made clear that the Trump administration has made the issue a core national defense mission. Hegseth also stressed that the U.S. military was deployed to the border and said the 101st Airborne’s command structure was involved in operational control there.
Citing Operation Southern Spear, Hegseth referred to an offensive posture in the region, one that has moved from surveillance and interdiction to offensive maritime action. Operation Southern Spear is an interagency mission that began in January 2025 as a 4th Fleet effort to use “Robotic and Autonomous Systems (RAS) to support the detection and monitoring of illicit trafficking” in the SOUTHCOM theater.
According to the Jan. 28, 2025 press release from the U.S. Naval Forces Southern Command,
Operation Southern Spear will deploy long-dwell robotic surface vessels, small robotic interceptor boats, and vertical take-off and landing robotic air vessels to the USSOUTHCOM AOR. 4th Fleet will operationalize these unmanned systems through integration with U.S. Coast Guard cutters at sea and operations centers at 4th Fleet and Joint Interagency Task Force South. Southern Spear’s results will help determine combinations of unmanned vehicles and manned forces needed to provide coordinated maritime domain awareness and conduct counternarcotics operations.
By late 2025, it had expanded into a Joint Task Force Southern Spear campaign under U.S. Southern Command involving kinetic strikes, maritime interdictions, and tanker seizures carried out with support from the USS Gerald R. Ford and the Amphibious Ready Group. In a Dec. 2, 2025 press conference, Pentagon press secretary Kingsley Wilson told the media there were “to date, a total of 21 kinetic strikes in U.S. Southern Command’s area of operations ... resulting in 82 suspected narco-terrorists having been killed.”
Official Pentagon and SOUTHCOM statements portray it as an interagency mission with DHS, the Coast Guard, and DOJ aimed at crushing illicit activity, defending the homeland, and restoring security in the Western Hemisphere. An important part of Southern Spear is its “quarantine” of sanctioned vessels in the Caribbean, with the U.S. declaring that “the only oil leaving Venezuela will be oil that is coordinated properly and lawfully.” It is a broad regional security and coercive maritime enforcement mission.
Hegseth went on to say that fentanyl flows are down 56 percent, calling fentanyl a “weapon of mass destruction.” He boasted of Maduro’s and his wife’s capture in January, alluding to the difficulty of the operation.
The Trump administration is committed to a much larger mission than merely snuffing out narco-terrorists. Hegseth, Rubio, and Trump’s NSS address a larger civilizational and ideological framework, whereby these nations are offspring of Western civilization, sharing a more ordered Christian worldview, one that contrasts with a more violent and chaotic worldview dominated by “narco-communism, narco-tyranny, mass migration, and globalism.”
The Trump doctrine is broadly geostrategic. In that vein, Hegseth warned of adversaries that control ports, infrastructure, and choke points like the Panama Canal. Calling upon America’s neighbors to “embrace our shared geography,” he said that these are
the same adversaries that threaten our shared heritage, threaten our shared geography as well. They seek to displace the historic “North-South” relationship that we’ve always shared with some sort of a new “Global South” that excludes the United States and other Western nations but includes non-Western powers and other adversaries.
The answer to our challenge, Hegseth continued, is not to ignore our geography in the name of global interests, but to embrace our shared geography in the name of national interests. That is why President Trump has drawn a new strategic map from Greenland to the Gulf of America to the Panama Canal and its surrounding countries.
Hegseth also signaled a likely institutional shift at U.S. Southern Command, moving from more effete support systems to the rugged operational support needed “for this robust mission ahead.”
One of the great mistakes of the past was that our leaders didn’t provide the U.S. Southern Command with the support that it needed. It was a command chock full of lawyers, social workers, NGOs, [and] law enforcement. That’s changing.
Trump’s national security Cabinet members are on message. They share a muscular vision that treats cartel violence, porous borders, and foreign malign influence as interconnected national security threats requiring sustained regional action, not symbolic diplomacy. The Trump administration views the Western Hemisphere as a strategic neighborhood that must be defended through burden-sharing, operational coordination, and a renewed expectation that partner nations will direct resources toward shared threats and objectives in defense of their own territory and sovereignty.
