Revisiting Operation Just Cause: A Historical Blueprint

Conducted in December 1989, Operation Just Cause saw the United States deploy roughly 26,000 troops into Panama to remove the military dictator General Manuel Noriega from power. A key justification included perceived threats to canal neutrality. Noriega was accused of destabilizing the region and jeopardizing safe passage through the canal. Under the broad interpretation of Article IV, the U.S. invoked the Neutrality Treaty to legitimize its military intervention.

“When the canal’s security and neutrality are in jeopardy, the U.S. has the right to act,” declared a Department of Defense official at the time.

The precedent is clear: The U.S. has previously utilized the Neutrality Treaty to justify a large-scale military incursion. Critics of Trump’s remarks who claim such an action “can’t be done lawfully” overlook this legal and historical context. While Operation Just Cause remains controversial—sparking debate at the United Nations General Assembly and among international observers—it legally hinged upon the very treaty provisions that are now being thrust back into the spotlight.

Alleged Violations Under Article IV: China and Panama

Trump’s talk also surfaces deeper geopolitical anxieties: the growing influence of China in Latin America. Chinese-based enterprises, including CK Hutchison Holdings (formerly Hutchison Whampoa Limited), have secured significant port concessions at both ends of the canal. Meanwhile, new Chinese-backed infrastructure projects continue to pop up across Panama.

From extensive port operations in Balboa and Cristobal to large-scale investments in bridges spanning the waterway, China’s footprint has never been larger. Detractors argue that Panama risks bending the neutrality clause by allowing a foreign power de facto control over these critical chokepoints. If China wields outsize leverage on canal operations—especially if its political and economic interests could overshadow universal access—the spirit and the letter of the Neutrality Treaty may indeed be threatened.

In my view, “If the Panamanian government, swayed by Chinese investments, undermines the equality of transit or toll rates, then we have a tangible case for a breach of Article IV obligations.” – Samuel A. Lopez

Looking Ahead: Could Another Operation Just Cause Happen?

If the Panamanian government’s fees become severely burdensome or it appears that Chinese influence is compromising the canal’s neutrality, the legal path for U.S. intervention—albeit drastic—still exists. That doesn’t mean the United States will or should march troops into Panama tomorrow, but it underscores that critiques of Trump’s statements as purely empty posturing may be misguided.

With increased tension around the globe and economic competition heating up, especially involving major powers like China, the Panama Canal remains a flashpoint worth watching. History shows that the U.S. government has not hesitated to exercise what it perceives as its rights under the Neutrality Treaty. Only time will tell whether Trump’s recent comments serve as a symbolic warning shot or the harbinger of a new, more confrontational approach.
