The United Kingdom(UK) has ended its intelligence sharing with the United States(US) in the Caribbean. British officials worry their information could help US forces carry out unlawful strikes on drug-trafficking boats.

This decision marks a sharp break from one of Britain’s closest allies. It also shows growing doubts in London about the legality of U.S. actions in the region.

Years of Cooperation Paused

For years, the UK helped the U.S. track drug-carrying vessels in Caribbean waters. The U.S. Coast Guard used this data to board ships, arrest crews, and seize narcotics.

Britain’s intelligence was shared through the Joint Interagency Task Force South, a multinational body based in Florida. The task force coordinates global efforts to stop illegal drug trade.

But after the U.S. began lethal strikes against these boats in September, the UK grew uneasy. Officials feared their intelligence might be used to pick strike targets.

76 People Killed in U.S. Strikes

The U.S. operations have killed 76 people since they began. British officials believe these attacks violate international law, as they target non-combatants on civilian vessels.

To avoid being seen as supporting such actions, the UK decided to withdraw intelligence support. London’s move shows it wants to distance itself from possible legal and ethical risks.

Tension Between Close Allies

Britain and the United States have long been close partners in defense and intelligence. This pause is rare and exposes growing policy differences over how to fight drug trafficking at sea.

Both nations still aim to combat the global drug trade. However, British officials insist that every operation must respect international law and human rights.
