On December 20, 1989, the United States launched a large-scale military operation in Panama, marking one of the final major U.S. military actions of the Cold War era. Known as Operation Just Cause, the invasion aimed to remove Panamanian leader Manuel Noriega, secure the Panama Canal, and protect American citizens living in the country.
At the time, Noriega, once an ally of the United States, had become increasingly hostile and was accused of drug trafficking, election interference, and human rights abuses. Tensions escalated throughout 1989, particularly after Noriega annulled national election results and declared that Panama was in a state of war with the United States. The killing of a U.S. Marine officer at a Panamanian checkpoint further heightened the crisis.
In the early hours of December 20, U.S. forces began coordinated attacks across key military and strategic targets. Approximately 27,000 U.S. troops, supported by airpower, were deployed alongside thousands already stationed in the Panama Canal Zone. The operation targeted the Panama Defense Forces, airfields, command centers, and government facilities.
Within days, U.S. forces overwhelmed Panamanian defenses. Noriega went into hiding before eventually seeking refuge in the Vatican embassy, where he surrendered on January 3, 1990. He was transported to the United States, tried on federal drug charges, and later convicted.
While the U.S. government stated that the operation sought to restore democracy and uphold international agreements regarding the Panama Canal, the invasion was controversial. Civilian casualties and damage to urban areas, particularly in Panama City, sparked international criticism and debate over the legality and human cost of the intervention.
In Panama, December 20 is remembered as a national day of mourning, honoring civilians who lost their lives during the invasion. In the United States, the operation is often viewed as a decisive military action that demonstrated rapid deployment capabilities and reshaped U.S. military doctrine entering the post Cold War era.
More than three decades later, the U.S. invasion of Panama remains a significant and complex chapter in both nations’ histories, reflecting the geopolitical tensions, strategic priorities, and human consequences of late 20th-century military intervention.
