That is an option, but we are still in the midst of a trade war with the US, who remains out largest trading partner.
If Carney can offer platitudes that cost nothing to get some goodwill with the US that might actually help Canadians, then why the fuck not?
Ultimately, Trump (and maybe some armchair policy experts) is the only person dumb enough to not see through this ploy. It's not going to affect his position in any negative way, and has a small chance to affect it positively.
I disagree with Carney on almost all of his real policy decisions, but the man knows how to play politics, and I'd much rather he be in office than PP.
