A United Nations finding that US strikes on suspected drug-trafficking vessels may constitute crimes against humanity has exposed a potential fault line in marine coverage: Washington describes the operation as an armed conflict, while the UN expert examining it says no such conflict exists.
That disagreement does not decide whether a policy would respond to a strike. It could, however, complicate how a future loss is classified if the campaign reaches an insured vessel, crew or third party.
The briefing note by UN Special Rapporteur Ben Saul examined 68 reported attacks that killed 223 people in the Caribbean and eastern Pacific from September 2025. The strikes took place outside US territorial waters.
“Such attacks amount to serial extrajudicial killings in violation of the right to life, being unjustified in national or personal self-defence or under international humanitarian law, the international law of the sea, narcotics suppression conventions, or international counter-terrorism law. There are reasonable grounds to believe that the reported 68 attacks that killed 223 people constituted crimes against humanity of murder under customary international law,” Saul said.
The finding does not have the force of a court judgment nor would an attack’s legality under international law necessarily determine its treatment under an insurance contract, which would turn on the event, the insured interest and the wording of the policy.
The competing legal positions nevertheless matter because ordinary hull and P&I policies commonly exclude war and related perils, which are insured separately. A loss involving military action by a state could therefore raise questions over whether conventional marine cover or war-risk insurance should respond, particularly if the vessel was not an intended target.
That remains a prospective risk rather than an established claims trend. The campaign has overwhelmingly targeted small craft associated by the US with drug trafficking. By late August, US Southern Command’s reported tally comprised 64 speedboats, three low-profile vessels and one semisubmersible craft—not conventional merchant ships.
There is also no indication of a broader regional reclassification by the London marine market. The Joint War Committee’s latest listed areas, issued on September 16, include Venezuela and its offshore installations but do not designate the Caribbean or eastern Pacific generally.
Listed areas identify locations where hull war, piracy, terrorism and related perils require closer consideration, although their application remains subject to negotiation under individual contracts. The absence of a wider designation indicates that the strikes have not yet produced the kind of market response seen when attacks threaten commercial traffic across a broader shipping corridor.
The immediate consideration is therefore more concentrated. Smaller commercial, fishing and private craft operating near known trafficking routes may present different identification and tracking risks from deep-sea cargo vessels. Accurate operating areas, ownership information, vessel identification and tracking practices could become more important in underwriting and in establishing the circumstances of a loss.
The consequences would become more complicated if a legitimate vessel were mistakenly targeted or an attack caused collateral injury, pollution or property damage. Coverage could then depend on how the act is characterized under the relevant hull, P&I and war-risk wordings, while any attempt to recover from the responsible state could add another layer of legal difficulty.
Operation Southern Spear began in September 2025. Defense Secretary Pete Hegseth has said it is intended to remove “narco-terrorists from our hemisphere” and protect the US from “the drugs that are killing our people.”
US authorities have generally released brief statements and surveillance footage after the attacks but have not publicly provided definitive evidence that every targeted vessel was carrying drugs.
The operation continued shortly before the UN note was released. In a September 19 strike, Southern Command said four people were killed aboard a vessel in the Caribbean.
“Confirmed intelligence revealed the vessel's active involvement in narco-trafficking. The operation killed four narco-terrorists,” Southcom said.
For now, the campaign has not produced losses involving commercial shipping or prompted a broader reassessment of Caribbean and eastern Pacific marine risk. The more immediate question is whether clients operating near the affected routes have a clear divide between conventional marine and war-risk protection.
That position could change quickly if a legitimate vessel is misidentified or the operation moves closer to commercial traffic.
