On 21 June, the United States Southern Command conducted a lethal kinetic strike on a vessel in the Caribbean, killing two men and leaving six survivors. According to a statement from the command, intelligence assessments confirmed the vessel was transiting known narco-trafficking routes and was engaged in drug-smuggling operations at the time. The six survivors were recovered after the US Coast Guard was notified to activate its search-and-rescue system. No American military personnel were harmed. The operation brings the total number of people killed in such strikes to more than 210 since the Trump administration began targeting what it calls “narcoterrorists” in early September 2025, with over 60 attacks now recorded.

Viewed from Washington, the campaign is framed as an armed conflict with Latin American cartels designated as terrorist organisations, a necessary escalation to stem the flow of illicit drugs, particularly fentanyl, into the United States. The White House has described a previous follow-up strike on survivors clinging to wreckage as an act of self-defence consistent with the laws of armed conflict. US Southern Command has not publicly identified the organisations allegedly operating the vessel, nor has it released evidence that drugs were on board. In Congress, some lawmakers have demanded the Pentagon release unedited video of the first such strike, and human rights organisations have characterised the operations as potential extrajudicial killings, questioning both their legality under international law and their effectiveness.

The Pentagon’s internal watchdog announced in May that it would examine whether the military followed the established six-phase Joint Targeting Cycle when carrying out the strikes. The evaluation, however, does not extend to the legality of the operations themselves. Legal scholars, particularly in the United States, have argued that a second strike on survivors would be unlawful under any circumstance, armed conflict or not. The debate is sharpened by the fact that fentanyl, the drug most often cited to justify the campaign, is primarily trafficked overland from Mexico and manufactured with precursor chemicals imported from China and India, according to analysts tracking supply chains.

These military strikes mark a departure from traditional US interdiction methods. A separate investigation by the Associated Press has revealed that between 2023 and 2025, the Drug Enforcement Administration permitted hundreds of thousands of fentanyl pills to reach streets in New Mexico, monitoring shipments without seizing them in order to build larger criminal cases. Current and former DEA agents told the AP the tactic amounted to a gamble with public safety that may have violated Justice Department guidelines. The Pentagon has not responded to questions about the fate of the survivors of the 21 June strike. The inspector general’s review is ongoing, and congressional pressure for greater transparency persists, with no announced change to the operational tempo of the Southern Spear task force.
