What are your thoughts on Carney declaring in his speech that Canada went along with a lying American world order because they thought they were safe, and that they cannot anymore?

That's not exactly what he said. The specific quote (with emphasis) is:

For decades, countries like Canada prospered under what we called the rules-based international order. We joined its institutions, praised its principles, and benefited from its predictability. We could pursue values-based foreign policies under its protection.

We knew the story of the international rules-based order was partially false. That the strongest would exempt themselves when convenient. That trade rules were enforced asymmetrically. And that international law applied with varying rigour depending on the identity of the accused or the victim.

This fiction was useful, and American hegemony, in particular, helped provide public goods: open sea lanes, a stable financial system, collective security, and support for frameworks for resolving disputes.

Partially is doing as much work there as false. The story of the rules-based order was partially false. But that's true for all systems of governance: they're built on stories that don't hold up to scrutiny, but they are useful, and often better than the alternative. It's a useful fiction in the way that talking about "universal human rights" is a useful fiction. Even if it's not strictly true it's better to believe in it (and have others believe in it) than the alternative.

The alternative to the "rules based international order" is the world we're seeing ourselves move towards, which was the subject of Carney's speech. What can we do when no one believes the lie that lets us stay at peace with each other? Carney answers:

[If] great powers abandon even the pretence of rules and values for the unhindered pursuit of their power and interests, the gains from ‘transactionalism’ become harder to replicate. Hegemons cannot continually monetize their relationships. Allies will diversify to hedge against uncertainty. Buy insurance. Increase options. This rebuilds sovereignty— sovereignty which was once grounded in rules—but which will be increasingly anchored in the ability to withstand pressure.

I've seen some people want to pick at his comments as though he's giving the game away, as if the rules-based order was never actually something that any of the global elite ever truly believed in. But it's the opposite. The rules-based order was something that many people in governance really, truly, wanted to believe in, and they've been willing to sustain the "lie" until it became untenable (as it has now). And it didn't fall apart for any reason other than that America, who upheld the "lie" more strongly than anyone and subsequently benefitted the most from it, decided that it would rather revert to an old mercantilist form of capitalism that predated the modern "transactional"/international capitalism.

Very happy with my PM in this current situation. That speech was historic and very accurate. I’m glad he said what he did. It gives me hope that some people in charge are seeing what many of us see.

I feel less anxious knowing that we elected a Prime Minister with the clarity to weather this crisis.

Bit of jealousy given how close Australia is with US but it's much less dire than Canada here. 

We do need a new Pacific partner though cos we can't go it alone. 

Right on the money. Jeffery Sachs’s has said it best, for too long, Western Europe and Canada has acted as vassal states to the U.S. and have allowed the U.S. for 30+ years to do whatever they want internationally all under the guise of “freedom” or “doing the right thing” because the countries that were being targeting by the U.S. did not affect them so they toed the company line.

I’m glad they’re giving pushback and other EU countries are saying Greenland is a redline the U.S. cannot cross.

Carney is a fantastic reminder of what a strong, intelligent, leader looks like. 

Compare Carney’s Davos speech with Trump’s rambling, insane press conference. The difference is astonishing.

Ever since this guy got elected I feel like I'm walking around a little taller with my head up and clear eyed about the world and future, ready for whatever crap comes along. I'm so pumped this guy is my prime minister and absolutely proud to be Canadian

Pretty darn brave. But someone has to call it out. The Americas are in trouble. Globalization is in trouble. Something has to change.

Striking bit of honesty in his speech. Tbh

Basically he is saying that the USA/Trump has betrayed Canada and he's not going to let that happen again.

Totally accurate.

Canada went along with the American order because it was convenient.

Since America has decided to burn all bridges it’s a good thing Carney is forging new relationships.
