This kind of hits at the fatal flaw in their thinking... They have assumed that their threats (and actions) will ratchet up pressure on Canadian and European governments and will automatically bring them to heel. Instead, they are basically causing rally around their flag effects elsewhere while, at home, our population is divided at best on the tariffs, and outright against conquests into Canada (in like the -60 to -70 range)
Their hubris will be our downfall as a country IMO
