UK Halts Intelligence Sharing with US Amid Lethal Boat-Strike Concerns
Britain pauses crucial drug-trafficking intelligence cooperation with the United States over alleged unlawful US maritime strikes in the Caribbean and eastern Pacific
The United Kingdom has suspended certain intelligence sharing with the United States concerning suspected drug-trafficking vessels in the Caribbean and eastern Pacific, in protest at what London regards as unlawful US military strikes.
The cut-off, which began more than a month ago, marks one of the most serious ruptures in recent memory between the two close intelligence allies.
According to informed sources, the UK grew deeply troubled after the US military initiated a campaign of lethal strikes against small boats alleged to be carrying narcotics from Latin America.
In one track of 19 recorded attacks since September, US forces reportedly killed at least 75 people.
British officials say they concluded these actions violated international law and could make the UK complicit in extrajudicial killings if it continued providing intelligence.
For years the UK had provided intelligence derived from its Caribbean territories to the US-led Joint Interagency Task Force South in Florida, supporting the US Coast Guard’s interdiction of suspected trafficking vessels.
The pause stems from a determination that the information might now be used by the US military—not law-enforcement agencies—to target boats for bombardment, rather than boarding and arrest.
The US administration under Donald Trump contends it is in an ‘armed conflict’ with drug cartels and that such strikes are lawful under the law of armed conflict.
Legal experts, the United Nations Office of the High Commissioner for Human Rights and British authorities counter that the attacks lack legal justification, and thus the UK cannot provide intelligence it fears will facilitate illegal actions.
A UK government spokesperson declined to comment on intelligence matters but reaffirmed that the United States remains a “closest ally on defence and intelligence”.
The move raises questions over the future of the Five Eyes intelligence-sharing network and the degree to which Britain will support US operations in the region.
With intelligence previously underpinning US naval deployments off Venezuela and in the Caribbean Sea, the disruption may diminish the effectiveness of future joint efforts against maritime drug trafficking and increase tensions across the alliance.
As the UK recalibrates its cooperation, Washington faces the prospect of operating without a key source of intelligence in the region—a reallocation that could influence both regional strategy and Anglo-American intelligence ties moving forward.
