The United States military launched a series of airstrikes on small boats operating in international waters in the Caribbean Sea and the eastern Pacific in September 2025. US officials said the vessels were linked to drug trafficking networks, presenting the attacks as part of a tougher counternarcotics campaign.
But as details of the operations came to light, they sparked growing alarm among legal experts, human rights groups, and international institutions.
What happened?
Investigative reporting by The New York Times revealed that the first known strike involved a US aircraft that had been modified to resemble a civilian plane. The aircraft carried no visible military markings, and its weapons were concealed inside the fuselage. From a distance, it was indistinguishable from a non-military aircraft.
That initial attack reportedly killed 11 people aboard the targeted boat. A second strike followed shortly after, hitting survivors who were already in the water. This โdouble-tapโ tactic drew particular criticism because those targeted no longer appeared to pose an immediate threat.
Since September 2025, the US military has carried out dozens of similar strikes across maritime routes in the Caribbean and Pacific. Independent estimates place the death toll at several dozen to more than a hundred, though US authorities have released limited information about those killed or the intelligence used to justify the attacks.
Why are these strikes controversial under international law?
At the center of the controversy is whether the operations comply with international humanitarian law. One of its core principles is that combatants must clearly distinguish themselves from civilians. Disguising a military aircraft as a civilian one to carry out a lethal attack may constitute perfidy, a prohibited act under the laws of war.
Perfidy involves feigning civilian or protected status to deceive an adversary before attacking. Legal experts warn that such practices undermine protections for civilians and erode long-established norms governing armed conflict.
Is the US legally at war with drug traffickers?
The US government has argued that the strikes are lawful because it is engaged in an armed conflict with transnational drug trafficking organizations. Many legal scholars strongly dispute this interpretation. They argue that drug trafficking is a criminal activity, not an armed conflict, and should be addressed through law enforcement rather than military force.
If no armed conflict exists, international human rights law applies. Under those rules, lethal force is permitted only when there is an imminent threat to life. Critics say the US has not demonstrated that such a threat was present in the boat attacks.
What about US law and oversight?
The strikes have also raised questions under US domestic law. Congress has not explicitly authorized the use of military force against suspected drug traffickers at sea. This has fueled debate over presidential war powers and the limits of executive authority.
Reports indicate that some military legal advisers were excluded from the planning process, intensifying concerns about whether the operations underwent sufficient legal scrutiny before being approved.
How has the world reacted?
International reaction has been swift. The United Nations human rights office has condemned the attacks as unacceptable and called for independent investigations, warning that the strikes may amount to extrajudicial killings.
Some Latin American governments have also expressed concern, with at least one country suspending aspects of intelligence cooperation with the United States in protest over the operations.
Why does this matter?
Beyond the immediate loss of life, experts warn that the implications of the US boat attacks could be far-reaching. Treating criminal activity as grounds for military action risks blurring the line between warfare and policing.
More broadly, the use of disguised military assets threatens to weaken international norms designed to protect civilians and regulate armed conflict. Critics warn that such practices could endanger civilian aviation and maritime operations worldwide.
While US officials continue to frame the campaign as a necessary response to illegal drugs, critics argue that the legal, moral, and geopolitical costs may far outweigh its gains. As calls for transparency and accountability grow, the controversy highlights deeper questions about how far states can go in the name of security โ and what happens when those limits are tested.
