(AP)President Donald Trump escalated his war of words with Canadian Prime Minister Mark Carney on Thursday, warning that Carney’s effort to cast the United States as an adversary will backfire as the two countries remain locked in an escalating trade battle.”It is very good for Canadian Politicians like Prime Minister Carney to make President Donald J. Trump ‘the enemy,’ until their Economy collapses, then it will prove to be very bad for Politics — Worse than anything that has ever happened to a Canadian Politician,” Trump wrote in a social media post. “Just watch!”Trump’s broadside came two days after Carney said Washington needed to “stop doing memes, stop throwing shade and stop trying to be tough” and get serious about trade negotiations.AdvertisementAdvertisementAdvertisementAdvertisementCarney said talks could resume if the Trump administration changed its approach, while accusing U.S. negotiators of seeking terms that threatened Canadian industries and sovereignty.Relations have deteriorated sharply since trade negotiations collapsed Aug. 21, with each side blaming the other for scuttling an agreement. Trump subsequently imposed 50% tariffs on roughly $20 billion in Canadian goods, while Ottawa announced plans for dollar-for-dollar retaliatory tariffs on U.S. products beginning Sept. 8.Treasury Secretary Scott Bessent on Wednesday blamed Carney for the impasse, saying the Canadian leader made a “political decision” to walk away when an agreement was on the “1-yard line.”Bessent predicted Carney would ultimately return to the negotiating table and warned that the next U.S. offer might be less favorable.Trump has also threatened additional tariffs on Canadian vehicles, auto parts, and steel beginning in January, further raising the stakes in the dispute.© 2026 Newsmax.
