“As the world digests Donald Trump’s self-declared tariff day, a heavy fog shrouds what happens next,” Bloomberg reports.“But it’s increasingly clear that the president’s rationale for imposing an array of seemingly arbitrary rates on countries’ exports to the US is every bit as political as it is economic.”“Take Canada, where Prime Minister Mark Carney won a spring election largely on the premise that he could take on Trump and get the tariffs removed. Since then, the nation has mostly watched from the sidelines as Trump focused on hammering out deals with other trade partners.”“Then yesterday, Trump hiked Canada’s tariff rate to an eye-watering 35% — even as he gave Mexico a 90-day reprieve.”
