Mark Carney Denied Trump His Steel—Detroit in Sharp Decline Overnight

Last week, Canadian Prime Minister Mark Carney delivered a devastating blow to Trump's trade strategy by declaring Canadian steel "not for sale." Within 48 hours, steel prices in the U.S. soared by 30%, triggering a supply chain crisis in Detroit that has left auto plants scrambling and workers laid off. This video argues that Trump's decision to increase steel tariffs to a crippling 50% didn't protect American jobs; it backfired spectacularly, exposing the fatal flaw in his "America First" policies. By cutting off a reliable Canadian supplier, Trump has plunged the American manufacturing heartland into a "supply chain recession," proving that in today's integrated North American economy, you cannot wage economic war on your neighbors without destroying your own industrial base.
