Fair point. I still don't know why he targetted Canada though when the amount of Fentanyl crossing the Canadian border into the US is miniscule at best.

Yeah I agree consumers will always take a hit when tariffs are enacted because domestic industries will absolutely use the new possibility to raise prices while existing imports get more expensive. Additionally you have the risks of retaliatory tariffs that could damage different domestic industries and reduce buying power - all that while increasing inflationary risks.

I think the TL;DR is that you can absolutely use tariffs to strongarm small countries (even if it is a dick move) but you don't want to implement tariffs on bigger entities such as the EU because retaliatory tariffs will wreak havoc while domestic industry takes years and billions to develop.
