So let me get this straight. As per your link, the weighted tariff rate is 0.98% in 2015. That is tiny. The average tariff rate with the European Union is about five times that. And again, this is before the updated USMCA deal that the US agreed to.

Please explain to me why a 0.98% average effective tariff rate justifies retribution in the form of 25% to 50% tariffs.

Please also explain why it's justifiable, again, for a 0.98% effective tariff rate, to threaten to economically destroy a country and force it to be annexed. To be clear, even with massive economic damage to Canada, we will not be willingly annexed, ever. If you want our country, you must invade. That is ultimately what the annexation threat is. It is a threat of invasion.

Then why did Trump choose to negotiate and sign the USMCA?
