Trumpism, when seen from Near Afar of the America, is only a symptom of the deepest societal crisis since the Great Depression; the Dem Party, especially neocon wing, proudly shares their part of responsiblity for this, and for erosion of the American Republic on its path of (failed) transition according to geopolitical reality of the day.
That is to say, quite possibly Trump's victory, be it first or second one, is not an anomaly and a statistical spike protruding below the surface, but instead, "interregnum" of Biden-Blinken-Harris administration had been.
Ditto tariffs: US import tariffs were, since the inception of NAFTA and up to now, not only among the lowest in the world, but in the history of the Union, too.
The twin deficits and the hidden side effects of the Triffin paradox finally eroded the core of a support pillar. You (Canada) will swim out of the whirlpool, but the EU, already shaken by three-years long energy crisis and recession in Germany, faces the prospect of the Japan-styled lost decade(s).
Though protectionist policy for the US would make total sense, hadn’t its economy been so much interdependent with NAFTA members. Nowadays any attempt at delinking from them is as moronic as the breakage of Chimerica, which definitely brought, and will bring again, more harm than good to both sides, but especially to the US. Turkey shows a better example of such a strategy.
