United States forces are carrying out lethal strikes on small boats suspected of smuggling cocaine toward Central and South America, turning a long running drug war into a campaign of targeted killings at sea. Legal experts across the political spectrum say the operation rests on shaky ground, arguing that neither the law of armed conflict nor peacetime human rights rules clearly authorize the use of missiles and machine guns against alleged traffickers. Their criticism has sharpened as details emerge about specific attacks, including a controversial “double tap” strike on survivors in the water.
At stake is more than the legality of a single mission. The Trump administration is testing how far the United States can stretch concepts like self defense, terrorism, and armed conflict to justify military force against non state criminal networks, and whether Washington can do so without accepting the full set of rules that normally govern war.
Escalating firepower against drug boats
The United States has quietly transformed maritime drug interdiction from a law enforcement task into a kinetic military campaign. Under what the Pentagon calls Operation Southern Spear, officials say there have been a total of 21 kinetic strikes in United States Southern Command’s area of operations, resulting in 82 confirmed deaths of suspected traffickers and the destruction of multiple vessels and cargoes. According to a running tally of the 2025 United States military strikes on alleged drug traffickers, at least 87 people have been killed as of early December, with bodies recovered from the sea and repatriated to their home countries.
Unlike traditional Coast Guard chases and boardings, these missions often involve aircraft firing on small boats far from United States shores, sometimes at night and without any apparent attempt to hail or capture the crews first. Reporting on the operation describes attacks on vessels in international waters off Central and South America, with nearly two dozen strikes carried out against alleged drug boats in that region. The Pentagon frames the campaign as a necessary response to transnational cartels that move cocaine and other narcotics by sea, but the choice to rely on missiles and heavy weapons rather than arrests marks a decisive escalation in how the United States wages its war on drugs.
The administration’s shifting legal story
To justify this escalation, the Trump administration has floated overlapping and sometimes conflicting legal theories. Officials have suggested that the United States is engaged in an armed conflict with powerful cartels, that international drug trafficking amounts to a form of terrorism, and that the president can rely on inherent self defense powers to strike boats that might eventually send narcotics toward United States territory. In public and classified briefings, lawmakers have been told that the operation is part of a broader pressure campaign on Venezuela and other regional actors, blurring the line between counter narcotics and coercive diplomacy.
Critics say these arguments do not add up. One detailed analysis of the attacks notes that the administration “wants to call it armed conflict but not follow the rules of armed conflict,” highlighting the contradiction in claiming the benefits of a war footing while rejecting the constraints that come with it. Earlier commentary on Trump’s military pressure on Venezuela warned that labeling drug traffickers as terrorists and tying them to a hostile government risks collapsing the distinction between crime control and war, a concern that has only grown as the White House now tries to rebrand international drug trafficking as “terrorism” to unlock broader military authorities. Members of Congress, including Independent Sen Angus King of Maine on the Senate Armed Services Committee, have pressed for a clearer explanation of the legal basis, but so far the administration has offered only high level references to national security and presidential power.
Why most legal experts see no lawful armed conflict
International law specialists who have examined the strikes almost uniformly reject the idea that the United States is in a genuine armed conflict with maritime smugglers. For the law of armed conflict to apply, there must be sustained, intense hostilities between organized armed groups, not sporadic attacks on unarmed or lightly armed boats ferrying contraband. One expert assessment of Operation Southern Spear concludes that there is “no armed conflict” between the United States and suspected traffickers at sea, and that there is “near unanimity” among law of armed conflict experts on this point. A separate Q&A with scholars of International human rights law similarly finds that the strikes are not part of a recognized war, but instead amount to extrajudicial killings that must be judged under peacetime standards.
William Burke White, a former State Department lawyer, has argued that destroying small boats and killing their crews to prevent possible drug shipments “cannot plausibly be justified” as a form of anticipatory self defense or as lawful conduct under international law. In his view, the fact that these vessels may be carrying cocaine does not transform them into legitimate military targets, particularly when they pose no imminent threat to life. Other commentators emphasize that even if the United States could somehow characterize the situation as an armed conflict, it would still need to show that each person targeted is a combatant or directly participating in hostilities, a threshold that is hard to meet when the individuals are alleged smugglers rather than fighters. The bottom line from these analyses is stark: if the United States is not in a war with these crews, then the killings must comply with human rights law, which allows lethal force only when strictly necessary to protect life, not to enforce drug prohibition.
Human rights rules and the problem of “double tap” strikes
The most disturbing allegations involve not only the initial attacks on boats, but follow on fire against survivors in the water. In one widely discussed incident, a small vessel was reportedly destroyed in a “double tap” strike, with a second round of munitions or gunfire directed at people who had already been knocked overboard and were “technically out of combat.” Legal experts interviewed about what the law says regarding killing survivors of a boat strike stress that, outside a lawful armed conflict, shooting at shipwrecked individuals is almost impossible to reconcile with international human rights obligations. Even in wartime, the law of armed conflict protects those who are hors de combat, including wounded or shipwrecked persons who are attempting to surrender or are no longer taking part in hostilities.
Those concerns intensified after Admiral Bradley publicly denied giving an order to fire on survivors during an appearance at the Reagan National Defense Forum, saying “of course” he would not authorize such an action. His denial has not ended scrutiny, however, and the allegations have sparked investigations into whether there was an attempt to surrender and whether crews were targeted despite being defenseless. A detailed breakdown of the legal issues notes that, if international human rights law applies, then the deliberate killing of survivors who pose no imminent threat would qualify as an unlawful deprivation of life. Even analysts who are more sympathetic to aggressive counter narcotics operations warn that “double tap” tactics, familiar from counterterrorism campaigns, are especially hard to square with any plausible legal framework when used against suspected smugglers at sea.
Domestic authority and congressional unease
Beyond international law, scholars are also questioning whether the president has a solid domestic legal foundation for the campaign. The strikes have not been clearly tied to any existing Authorization for Use of Military Force, and there is no new statute that explicitly authorizes lethal force against drug traffickers on the high seas. Some legal commentators argue that the administration is relying on a broad reading of the president’s Article II powers and on general counter narcotics authorities that were designed for interdiction and support missions, not for targeted killings. A detailed review of the operation’s legal underpinnings concludes that if the United States is not bending the law, “it is breaking it,” because the claimed authorities do not stretch far enough to cover repeated missile strikes on non state criminal suspects.
Members of Congress are starting to push back. After reports that the United States has conducted nearly two dozen strikes against alleged drug boats off Central and South America, lawmakers demanded a “full accounting” from the Pentagon and asked whether the president had exceeded his mandate. Some have raised concerns that rebranding traffickers as terrorists and invoking a perpetual global war on drugs could sidestep the legislature’s role in authorizing force. Others worry that the administration’s approach will make it harder to secure cooperation from regional partners, who may see the operation as a violation of their sovereignty or as an invitation to treat their own criminal problems as pretexts for military action. The growing unease on Capitol Hill suggests that the legal debate is moving from academic journals into the core of United States war powers politics.
Rule of law costs and global precedent
For many legal scholars, the most serious consequence of the boat strikes is the damage they inflict on the broader rule of law. Commentators warn that by treating international drug trafficking as terrorism and using that label to justify lethal force, the administration is eroding the carefully built distinction between policing and war. One prominent international law professor argues that the attempt to rebrand traffickers as terrorists “compounds” the danger, because it invites other states to follow suit and to use counterterrorism rhetoric to rationalize attacks on political opponents or ordinary criminals. A detailed commentary on the attacks describes them as part of a pattern in which the United States seeks to expand the category of threats that can be met with military force, while resisting the corresponding expansion of legal constraints.
Analysts at Just Security have gone further, warning that Operation Southern Spear risks normalizing a model in which powerful countries claim a right to kill suspected criminals in international waters without trial, based on secret intelligence and elastic legal theories. Their Collection on Lethal Strikes against Suspected Drug Traffickers highlights the danger that other governments will cite the United States example to justify their own maritime crackdowns, including against migrants or dissidents. If the United States insists that it can unilaterally decide when a smuggler becomes a legitimate target, critics say, it will be harder to object when rivals adopt the same logic. For a country that has long championed freedom of navigation and the law of the sea, that is a steep price to pay for a marginal tactical gain in the war on cocaine.
