And this tariff deal will be outside of CUSMA.
It will be us giving up concessions (which may then be expected in CUSMA talks down the line) to get a reduced tariff rate.
This wont go to congress, it wont be ratified, it just executive power that sets the rates, aka, a ART, not a FTA.
So when trump goes back to the well 6 months from now with new tariffs asking for more concessions, what then? We will have already agreed to concessions earlier.
It's like when Churchill asked a woman how much for a night, and she balked when the price dropped, asking what kind of woman he thought she was. Churchill said what kind of woman she was had already been established, and now they were just haggling over price.
We give in to this blatant extortion attempt, and we position ourselves as a nation who simply rolls over and takes whatever unjust ART he decides on, and if it happens again, we will roll over again.
Let the 19th pass, and suspend trade talks. Sure it may hurt but at least we dont give into these bully tactics. If we give up the lunch money now, they will come for it again next week.
