Washington — September 22, 2026 | PK News

A United Nations human rights expert has raised serious questions about the legality of a US military campaign targeting vessels suspected of carrying illegal drugs in the Caribbean Sea and eastern Pacific Ocean, saying the attacks may amount to crimes against humanity.

The assessment concerns Operation Southern Spear, the US-led campaign launched in 2025 against vessels Washington says are connected to drug-trafficking networks. According to the UN briefing, 68 reported attacks had killed 223 people by the time of the assessment. More recent US military operations have pushed the publicly reported number of strikes and deaths even higher.

The controversy centers on whether suspected involvement in drug trafficking gives the United States a legal basis to use lethal military force against people aboard vessels outside US territorial waters.

UN Expert Challenges the Legal Basis

UN Special Rapporteur on counter-terrorism and human rights Ben Saul said there were reasonable grounds to believe that the reported attacks constituted crimes against humanity involving murder under customary international law.

The report argues that suspected drug trafficking does not, by itself, constitute an armed attack against the United States and therefore does not automatically provide a justification for military force under the right of self-defense.

It also questions whether international humanitarian law applies to the operations, arguing that the people aboard the targeted vessels were not automatically lawful military targets simply because they were suspected of participating in criminal activity.

The UN assessment is not a criminal conviction or binding court ruling. It is an expert finding that could nevertheless become relevant in future legal and diplomatic discussions.

Washington's Position

The Trump administration has described the people targeted in the campaign as members of drug-trafficking organizations and has used the term “narco-terrorists” to describe them.

US Southern Command has repeatedly said that intelligence showed targeted vessels were involved in narcotics trafficking. In one of the latest strikes, US officials said four people were killed aboard a vessel operating along established trafficking routes in the Caribbean.

US officials have argued that the military campaign is necessary to disrupt networks responsible for bringing illegal drugs toward the United States.

However, public information released after individual strikes has generally provided limited details about the intelligence used to establish what was allegedly being transported on each vessel. AP reported that US authorities had not publicly provided direct evidence that the vessels in the campaign were carrying narcotics.

Why the First Strikes Became Controversial

The campaign has faced particular scrutiny because some people initially survived individual attacks.

Human Rights Watch and other organizations have documented concerns surrounding the treatment of survivors and the use of lethal force against suspected drug-trafficking vessels.

A separate investigation by the Washington Office on Latin America reported that the first strike in September 2025 initially left two people alive in the water. The organization says those survivors were subsequently killed in a follow-up attack. These allegations have become part of the broader debate over whether the campaign is consistent with international law.

The US government's handling of survivors has therefore become an important issue alongside the question of whether the original strikes were lawful.

Operation Southern Spear

Operation Southern Spear became the name associated with the US military campaign against suspected maritime drug trafficking.

The operation has involved US military forces operating in the Caribbean and eastern Pacific, areas that are known routes for maritime trafficking.

According to a review by the Washington Office on Latin America, publicly announced strikes through July 2026 had resulted in hundreds of deaths, although the exact total has changed as new operations have been reported. The organization also noted that the Defense Department has not publicly released a complete accounting of every operation carried out under the campaign.

A separate timeline tracking the campaign reported 70 strikes and 234 deaths as of September 19, 2026, illustrating how quickly the figures have changed.

Does Drug Trafficking Justify Military Force?

This is at the center of the international legal debate.

The UN assessment says that even if individuals aboard a vessel are genuinely involved in drug trafficking, that criminal activity does not automatically turn them into military targets.

Under the UN expert's analysis, using military force against people suspected of trafficking drugs would require another applicable legal justification, such as lawful self-defense against an imminent armed threat or another recognized basis for the use of force.

The report also argues that international maritime law does not independently authorize offensive military attacks against vessels suspected of drug trafficking.

This distinction is important because traditional counter-narcotics operations normally involve interception, boarding, searches, arrests and prosecution rather than military attacks intended to kill those aboard.

Former DEA Official Questions the Strategy

In an interview reflected in the transcript provided to PK News, Mike Vigil, a former chief of international operations at the US Drug Enforcement Administration, criticized the strategy.

Vigil argued that the United States should focus more heavily on reducing domestic demand for illegal drugs, expanding treatment and prevention programs, and disrupting the financial and weapons networks supporting criminal organizations.

He also questioned whether the use of military force against suspected traffickers was producing measurable results.

His comments represent one expert's assessment rather than an official US government position.

The Demand Problem

The debate also extends beyond the military campaign itself.

The United States has one of the world's largest markets for illegal drugs, and American demand generates substantial revenue for criminal organizations operating throughout Latin America.

Experts who favor greater emphasis on public-health and law-enforcement measures argue that attacking individual boats addresses only one part of a much larger trafficking system.

Drug networks can replace individual couriers and vessels relatively quickly, while demand remains.

This has led to continuing debate over whether military strikes can significantly disrupt the broader supply chain without simultaneous action against money laundering, weapons trafficking, corruption and domestic drug consumption.

Concerns for Fishermen and Civilian Boats

Another concern involves people who operate legitimate vessels in the same waters used by traffickers.

The Caribbean and eastern Pacific contain extensive commercial fishing activity involving thousands of people. Fishing boats can operate far from shore for extended periods, sometimes in areas also used by criminal networks.

Human-rights organizations have warned that a policy based on limited publicly available information could create risks for people who are not involved in trafficking.

Accurate identification and verification therefore remain central to the legal and humanitarian debate.

US Campaign Continues

Despite international criticism, the US military has continued announcing operations.

On September 19, US Southern Command reported another strike against a suspected trafficking vessel in the Caribbean. Four people were reported killed. The military said intelligence had confirmed the vessel's involvement in narcotics trafficking.

The latest action demonstrates that the UN criticism has not, at least so far, resulted in an immediate suspension of the campaign.

The United States continues to maintain that its operations are directed against criminal networks responsible for drug trafficking.

What Comes Next?

The UN assessment could increase pressure on Washington to provide more information about the legal framework, intelligence and targeting procedures behind the strikes.

Questions are likely to focus on several areas:

What evidence does the US possess before authorizing a strike?
How are suspected traffickers distinguished from legitimate fishermen?
What legal authority permits lethal military action against suspected drug traffickers?
What procedures exist for rescuing survivors?
How are civilian casualties investigated?
What measurable effect has the campaign had on drug flows into the United States?

These questions are likely to remain at the center of international scrutiny as Operation Southern Spear continues.

PK News Analysis

The UN finding represents a serious legal challenge to the US campaign, but it should be understood as an assessment by a UN special rapporteur rather than a final judicial determination. The US government maintains that the targeted vessels are connected to drug-trafficking organizations and that military action is part of its effort to protect Americans from illegal drugs.

The central dispute is therefore both factual and legal: whether the intelligence behind individual strikes is sufficient and whether suspected drug trafficking provides a lawful basis for lethal military force.

As more information becomes available, future investigations, courts or international bodies could further assess the legality of the campaign.
