The violence spilling into Puerto Vallarta and across Jalisco makes clear that the drug cartels are not merely criminals operating in the shadows, they are a cross-border threat that demands decisive action. This piece argues that a president—especially one committed to securing the border—has both the authority and the responsibility to strike cartel infrastructure abroad, explains the constitutional and historical precedents that back such action, addresses the War Powers Act limits, and points to recent operations that show the administration is already treating cartels as an international security problem.
Cartels have turned large swaths of Mexican territory into zones of de facto control, collecting “taxes,” dictating movements and intimidating officials until local authority collapses. They have trafficked deadly synthetic opioids and flooded American communities with addiction and death, which is why treating this as a law enforcement problem alone misses the point. This is a security threat with clear cross-border implications, and Republicans believe we must respond with the full range of national power.
President Trump’s record on the border shows a willingness to treat cartels as a national security emergency rather than a mere crime wave, and that stance is rooted in the Constitution. When borders are breached by armed groups and when mass trafficking of lethal drugs is deliberate and systematic, the president has long exercised authority to protect Americans. The Framers designed the executive to act when swift force is necessary to defend the nation and its citizens.
History supports this approach. Early in the republic, Thomas Jefferson sent the Navy “to the shores of Tripoli” to stop pirates who were attacking American shipping and extorting tribute, acting before Congress formally authorized force. In the early 20th century, Woodrow Wilson sent forces after Pancho Villa under a claim of “hot pursuit,” conducting a “punitive expedition” when Mexican authorities could not or would not stop cross-border attacks. Those examples show that presidents have deployed military power against non-state actors abroad when American lives and commerce were threatened.
The War Powers Act is often cited by opponents as a legal roadblock, but its practical limits are modest. It requires notification to Congress within 48 hours and restricts engagements to 90 days without authorization, not an absolute bar to action. Presidents of both parties have launched operations in places like Haiti, Bosnia, and Libya without prior congressional declarations, and courts have never squarely rejected the executive’s authority to use force in circumstances like these.
It is important to be candid about the stakes: synthetic opioids like fentanyl and carfentanil are weapons in every sense when trafficked intentionally across the border, and cartel networks have enriched themselves at the cost of American lives. When non-state groups behave like armed sovereigns and export violence, the line between criminality and aggression blurs. Conservatives insist that the state must meet aggression with power instead of waiting passively for the next wave of victims.
Operation Southern Spear and other recent moves show an administration ready to target smuggling networks at sea and beyond our shores, striking vessels and logistics chains before lethal shipments reach U.S. neighborhoods. Those operations mirror past decisions to confront threats where they originate, not after they have already reached American soil. A proactive posture buys time and saves lives by disrupting the supply and leadership of criminal networks.
Legal and historical precedent gives the president room to act, but strength must be matched with clear objectives and accountability. Targeted strikes and interdictions should be designed to break trafficking networks, protect U.S. citizens, and pressure foreign partners to restore territorial control. Republicans believe that defending the homeland sometimes requires confronting enemies where they plan and launch harm, and that the Constitution and history support that duty of the executive.
