Canada PM Carney warns of 'extreme tail risk' of US military action, diversifies tech supply

Canadian Prime Minister Mark Carney has publicly acknowledged assessing an 'extreme risk' of US military action, including invasion, and confirmed Canada is undertaking military contingency planning and supply chain diversification in response. This unprecedented public statement from an allied leader signals a severe deterioration in bilateral relations, though specific details of the threat assessment and preparations remain undisclosed. The claims are based on Carney's own statements in a single interview, with high confidence in the statements themselves but medium confidence in the underlying threat's probability.
