Canadian Prime Minister Mark Carney criticized the White House on Tuesday following the accidental leak of sensitive U.S. military plans via the messaging app Signal.
Carney emphasized that the Five Eyes intelligence-sharing alliance—comprising Canada, the U.S., the UK, Australia, and New Zealand—must learn from this breach, which mistakenly included The Atlantic’s editor-in-chief, Jeffrey Goldberg, in a private discussion about U.S. airstrike plans on Yemen.
“When intelligence leaks happen, lessons must be learned to prevent future occurrences,” Carney stated in Halifax, Nova Scotia, when asked about the repercussions of the breach, Politico reported.
“This is a serious issue, and all lessons must be taken,” he added, stressing the importance of transparency in addressing such failures.
The Atlantic’s report on Monday shocked U.S. national security officials and lawmakers, while Politico later suggested that National Security Advisor Mike Waltz might take the fall for the mishap. However, President Donald Trump reaffirmed his confidence in Waltz during an interview with NBC News on Tuesday.
Carney’s comments come amid heightened tensions between Canada and the U.S., as Trump has threatened tariffs and even suggested Canada’s annexation as the 51st state.
