The UK government has ceased sharing intelligence with the US in the wake of strikes on suspected drug transportation vessels in the Caribbean. This decision marks a significant departure from the longstanding practice of cooperation between the UK and the US. The move was reportedly prompted by concerns about the legality of lethal US strikes near Latin America.
Having assisted the US Coast Guard in tracking down drug smugglers aiming to reach North America, the UK, which maintains control over several Caribbean islands, used to collaborate closely with the US in intercepting suspicious vessels, seizing drugs, and detaining crews.
Previously, the US provided intelligence to the UK leading to the apprehension of illegal drug traffickers. However, the situation changed when President Donald Trump authorized lethal strikes on multiple vessels off the Venezuelan coast. British intelligence estimates that these strikes have resulted in the deaths of 76 individuals and have breached international laws.
Following the initial strikes in September, the UK suspended intelligence-sharing with the US over a month ago. The Trump administration alleges that the targeted boats were carrying fentanyl, a substance linked to the US opioid crisis, and considers those onboard as “enemy combatants” engaged in armed conflict with the US. Questions have arisen regarding the status of the individuals killed and whether they were involved in drug trafficking.
Tensions have escalated, leading to standoffs between US Southern Command Admiral Alvin Holsey, who offered to resign during discussions with Secretary of War Pete Hegseth. Admiral Holsey is expected to step down from his position in December, only a year after assuming the role.
As of mid-2025, US Customs and Border Protection had confiscated over 4,182kg of fentanyl, predominantly along the southern border with Mexico. Opioid-related deaths have claimed tens of thousands of lives in the US, with fentanyl overdoses being a major contributor to the crisis.
