Canada should use this as an opportunity to cancel dairy quotas in CUSMA. RFK advocates for raw milk. The pubic safety is at risk.
It also gives the US a solid economic fuck you that costs us nothing. We don't really export any milk to them, so all it does is remove the competition in our dairy market. And CUSMA is dead anyway, Trump killed it.
I suspect you grossly underestimate the dependence of the US economy on other countries, and I believe that you grossly misrepresent Carney in regard to the carbon tax (which you also misunderstand) and the WEF (which you assert to be a secretive global cabal of communists, ignoring the real and blatant fascist oligarchy in the US).
Putting all of that aside, Carney is by far the most experienced candidate we've had in decades, and I say this as someone who has lived 5+ decades in this country. And if you don't see the US as an existential threat then you're not seriously considering the magnitude of these events. Whether or not Trump decides to go through with any of it, he has destroyed the US reputation and our alliance for generations. The die is cast, and things will be different. The US is not our friend and may even be considered an enemy now but they are for sure unreliable, unpredictable, and possessing of malicious intent.
And any treasonous Yank sympathizers should just get out before they're put out.
