Story summary

In a recent interview with The New York Times, Prime Minister Mark Carney discussed the possibility that President Donald Trump might order military action against Canada, describing it as an "extreme tail risk" – a highly unlikely but possible scenario. Carney said it would be irresponsible not to prepare for such improbable events, touching on broader topics like F-35 jets and trade issues during his interview. A professor from the University of Toronto agreed that considering this scenario is valid given current international tensions. The BBC reported Canadians' reactions to these concerns, highlighting the unusual nature of preparing for a US invasion despite its low probability.

Canadians → add → that
