Last week, President Donald Trump announced that the United States military completed an operation – a lethal strike on a boat traveling through international waters carrying 11 Venezuelans. The Trump administration claims that those onboard the boat were drug smugglers and members of Tren De Argua, a Venezuelan gang, with the president going so far as to refer to them as “terrorists.” The administration has not, at least publicly, provided evidence to substantiate their accusations. Nor did they brief any members of Congress on their intentions prior to the attack.
Information about the strike is still trickling out, and in some cases it is shifting. Secretary of State Marco Rubio initially stated the vessel was likely headed to Trinidad and Tobago or another Caribbean nation, yet dropped this claim after Trump said it was headed towards the U.S. The New York Times now reports that the boat had turned around prior to the strike after those on it spotted military aircraft. Senator Rand Paul informed The Intercept that the military carried out the attack via drone strike, and the same outlet reports that follow-up strikes killed survivors of the initial attack. Senator Jack Reed, the ranking democrat on the Senate Armed Services committee, said that the Pentagon has “offered no positive identification that the boat was Venezuelan, nor that its crew were members of Tren de Aragua or any other cartel,” following a Congressional briefing.
Many have criticized this act as violating both national and international law. To put it bluntly, the U.S. military killed 11 foreign citizens based on an accusation of wrongdoing. Part 8 of the United Nations Convention on the Law of the Sea establishes that international waters shall be utilized for peaceful purposes, and force should only be deployed as a last resort. While the U.S. is not a signatory to the convention, as the senate never formally considered the treaty, the military’s position across several administrations has been to comply with its parameters. The strike likely violates the charter of the U.N., as the vessel did not appear to be engaged in an attack against the U.S. Article 6 of the International Covenant on Civil and Political Rights – to which the U.S. is a signatory – affirms that the right to life is protected by law and no one shall be killed arbitrarily. Furthermore, U.S. code labels the murder of civilians as a war crime, even if those civilians are in the midst of lawbreaking. So, the act appears illegal even according to U.S. law for wartime conduct.
However, I am not a lawyer. So I cannot assess legality beyond mere appearance. But I am an ethicist! The law and morality often diverge; one may have legal permission to do morally abhorrent things, while other times righteous actions may be illegal. So, instead I want to assess whether this operation can be morally justified.
I have elsewhere critiqued actions undertaken by this administration without due process and argued for the moral importance of this concept to punishment. I will not repeat that argument here, other than simply to emphasize the following. Without due process, no one’s rights are safe; the mere accusation that one is a member of some group purported to be engaged in illicit activity becomes sufficient for punishment. We should adopt a stance of serious moral skepticism toward any punishment doled out without a process intended to ensure the accusations are correct.
So, for our purposes let us set aside concerns about process and instead focus on outcome. Suppose that all of the administration’s accusations are true: the ship was occupied by gang members, intent on smuggling drugs into the U.S. Would this justify the use of lethal force?
Members of the administration have argued that the attack was a matter of national defense. Rubio declared that the U.S. has the right “to eliminate imminent threats” and Vance claimed that attack “kill[ed] cartel members who poison our fellow citizens” while praising this as the “highest and best use of our military.” During 2023, there were 105,007 (31.3 per 100,000 people) documented drug overdose deaths in the U.S. according to the CDC. But for the presence of those drugs, those people would presumably be alive. Thus, according to this argument, those who smuggle drugs into the U.S. pose potentially lethal threats to American citizens. So, the act of striking the alleged smugglers was an attempt to pre-emptively save the lives of those who would otherwise die of an overdose.
To assess the merit of this justification, we must consider some general features of the morality of defense. Just war theorists, those who study the moral justification of military force, often analyze considerations about national defense by determining first what justifies the use of lethal defensive force in the context of self-defense.They then attempt to “scale up” that justification to the level of a nation.
To avoid some of the complexities of this case – that the individuals killed are not members of a uniformed military, that the U.S. is not in a declared war against enemy combatants, that the strike occurred in international waters rather than within a nation’s borders – let us leave the analysis at the level of self-defense. My assumption is that, if the argument from individual self-defense fails here, then it will certainly fail when the waters are muddied with even further details which analyze this as a military act.
Back in August, Matthew Silk discussed justified conditions for self-defense in the context of Canadian law. Among the conditions that Silk raised is the idea that self-defense generally must be an appropriate response to the threat. He gives the example of responding to someone pushing you by striking them with a tire iron as an egregious case. While Silk considers the reasonability of this response, as Canadian law codifies it, philosophers discuss this idea in terms of proportionality: that the force with which you respond ought to be of a similar magnitude to the threat you face.
I agree with Silk that responding to a push with a weapon is unreasonable and disproportionate. But I want to mine Silk’s example further. Notice that while a push is hardly a severe assault, it is still potentially lethal. There is a chance, however remote, that one could die from a push – annually, several thousand people in the U.S. die from traumatic brain injuries caused by falls.
Nonetheless, striking a pusher with a tire iron would be too much. The remote chance of death does not justify a disproportionate response. This case does help illuminate, though, that threats we face are all a matter of risk. Suppose a stranger shouts that he wants to kill me and pulls out a gun. At this moment, it is still a matter of chance that I even suffer injury; perhaps this is some kind of sick joke, he may miss the shot, the gun could misfire, etc. However, even though it is not guaranteed that I suffer harm, I’d still be justified in drawing my own gun and firing to defend myself (provided I’m a quicker draw than the Waco Kid). The stranger is liable to lethal defensive harm on my part because of the magnitude and severity of the risk he imposes upon me. The pusher, however, is not liable to the same defensive harm; although a push could be lethal, the chances of its being so are quite low.
With this in mind, we can reassess the risk posed by the alleged drug boat to American citizens. The earlier figure of overdose deaths was due to all drugs in the United States. To be clear, each of these deaths is an avoidable tragedy. But it is not clear that a single drug smuggling operation is sufficient to significantly raise the risk of death for any specific person – for each of the last three years, U.S. Customs and Border Patrol reports that it seized between 550,000 and 660,000 pounds of drugs. Keep in mind that these are drugs seized; the amount that enters the U.S. is likely an order of magnitude greater. Given the scale of the operation, a speedboat containing 11 people and the scope of drug use in the U.S., it seems unlikely that the risk imposed here is sufficient to make lethal force proportional. It is analogous to destroying a cargo ship and its crew who are knowingly importing faulty, aftermarket brake pads; it has the potential to contribute to a larger problem, in this case automobile deaths, but the risk of death is small and distant enough that we would not be justified in using lethal force to prevent it.
However, even if one believes that the risk of harm posed by additional drugs arriving in the U.S. would be sufficient to justify lethal force, this is only one part of the moral calculus. Proportionality is a necessary condition to justify lethal force, but so is necessity. Suppose in my earlier case that the man trying to kill me was the victim of reverse-Manchurian candidate style programming, where speaking an activation word causes him to fall unconscious. Suppose further that I know the activation word. If my options are to utter it and make him fall unconscious, or shoot him dead, it seems I am no longer justified in shooting him. Once there are viable non-lethal options available to remove a threat, the use of lethal force is no longer morally justified.
And it is here that the moral justification of the attack unravels. To strike the vessel, the administration must have been tracking its movements. If it were traveling to the U.S., they could have been aware of the precise moment when it entered U.S. territorial waters. At this point then the U.S. Coast Guard would have the authority to intercept the ship.
There is much to find deeply troubling about this act. The process by which this course of action was decided upon has been wholly opaque. Its legality is, at best, highly dubious. Further, even if we take every claim by members of the administration at its word, the act fails to meet even the most basic standards of moral justification. The lethality of the threat posed by these individuals was both small and remote while there were non-lethal means available to eliminate the threat. Transnational drug smuggling operations, and the cartels that manage them, do pose a serious risk to the safety of innocents throughout the world. But our solution to dissolving these threats should not involve abandoning our moral standards.
