Sinking a Boat Is Not Law Enforcement

Proportionality at stake

The U.S. Navy recently destroyed a fast boat leaving Venezuela, killing 11 people allegedly linked to the Tren de Aragua gang. Officials described it as a counter-narcotics operation aimed at protecting public health. (US Navy Institute).

While drug trafficking is a serious threat, the use of missiles against an unarmed vessel raises fundamental legal and ethical questions and puts the legal principle of proportionality at stake.

International Law Requires Consent and Cooperation

Under the UN Convention on the Law of the Sea (UNCLOS) and the 1988 UN Drug Trafficking Convention, states must act in cooperation, often requiring flag-state consent before boarding or seizing vessels. The brilliant Prof. Natalie Klein notes that international rules “retain the need for flag-state authorisation.” (Natalie’s book).

These treaties envision inspection, boarding, and arrest – not instant destruction. The law prioritises due process and the protection of life, even for suspected criminals. Hence, this assault puts proportionality at stake.

The “Immediate Threat” Argument

The U.S. administration claims the strike was justified because the boat posed an “immediate threat” to public health. But international law interprets immediate danger as a direct, imminent risk to life or property – at sea. A general risk from potential drug trafficking does not meet this threshold. (EJIL article).

Missiles in this context are disproportionate. Law enforcement should be measured: cooperate, inspect, and arrest. Sinking a vessel without imminent threat exceeds what proportionality allows.

So What?

This is not a legal technicality that puts proportionality at stake. How states respond to crime at sea sets precedents for human life, international order, and accountability. Disproportionate force risks normalising extrajudicial killings.

Policy makers, legal scholars, and military legal advisors cannot remain silent. They must debate and clarify acceptable rules of engagement. Any deaths at sea demand a prompt, independent, and transparent investigation. Proportionality and consent are not optional—they are essential to justice and international trust.

Bottom line: Cooperation and proportionality – not “sink it first, ask questions later” – should guide law enforcement at sea.
