And won't the dems just undo all this tariff nonsense anyway? Or is Canada acting like a bitter ex after a breakup who vows to take their seething to the grave no matter what
I think the metaphor you're looking for is from the "USA as an abusive ex" angle, not a "bitter ex" metaphor that shifts blame to others...
There is no guarantee the Democrats are going to reverse the tariffs. And even if they do, the Republicans after that can just undo the undoing, and then do worse.
If you're still looking at this through the lens of party politics, you're missing the big picture. Most of US power comes not from its military, but its economic system. And that depends on trust and reliability. Both "sides" have been engaged in a project to scuttle that as hard and fast as they can since the end of the Cold War.
Both sides demonstrate that the United States can be consistently relied upon to break every deal they make, be it relating to international relations and borders, economics and debt, trade, military protection, and supply of arms.
Bush Sr and Clinton both broke the assurances made to Gorbachev that made the relatively peaceful dismantling of the Soviet Union possible by marching NATO eastward and carving up fresh borders in the Balkans.
Clinton, Bush Jr, and even Biden were still talking about free trade agreements, less than a decade before we see an international tariff regime spring up, and the United States reserves subsidy carve-outs in every deal they make with other countries who they expect to open their markets.
US spending has been out of control for decades no matter who controls the White House or Congress, and is only getting worse. They're relying on the inertia of its massive economy to bear the inflationary burden by printing money. The biggest export of the US economy, Treasury Bonds - that is, debt - is now seen as unreliable, and other countries are dumping them like burning garbage. Indeed, the United States has already started defaulting on such loans to a growing number of nations, only they get to call it "sanctions" when they don't repay their loans. The rest of the world looks on in horror as they realise how much of their wealth is tied up in this make-believe that the United States can renege on or bully creditors into not divesting on a whim. This explains the skyrocketing price of gold.
Speaking of those creditors, a lot of them are gulf states. As in, Persian Gulf. They used to sell oil and buy Treasuries as investments. But since nearly every US base in the Persian Gulf has been effectively destroyed, every gulf state that participated in the war crimes against Iran has been punished into submission for that involvement. Resumption of hostilities like we saw in the opening month would see the infrastructure that those nations rely on to continue to function as countries destroyed within hours. Absent desalination and oil export facilities, those countries would just cease to exist as significant polities. The de facto government in Yemen (referred to perversely as the "rebels", while the legitimate government sits in Riyadh, capital of the country that has been bombing Yemen for 15 years or so) just delivered Saudi Arabia a major military defeat, while the President refused to help. Saudi Arabia, land of black gold, unable to export from either the Strait or the Red Sea, with one of the biggest oil pipelines in the world now burning, is being forced to borrow money! The United States, so called most powerful military the world has known, dares not send a large naval vessel within about 1000 km of the Strait of Hormuz, and two aircraft carriers have been forced to limp away. Meanwhile, trade through the Red Sea has also been strangled off. All of the US allies under the protection of Pax Americana have been humbled by a country that has been getting "strangled" in some form or another for the past 70 years by a superpower.
And after all that the US military is out of interceptor missiles. They can't spare any for West Asia or Ukraine, right when everyone wants them. They wasted thousands of million dollar missiles on thousand dollar drones, and cannot make more at a rate that matters.
If you think it's just tariffs and some hurt feelings, you haven't been paying attention.
Bitter ex? This is amazing.
The US is a completely broken country, and simply switching governments will not change that. Without a complete and utter change in how that entire country operates -- including dissolution -- no country should ever normalize relations with it again.
The US is by far the world's most dangerous rogue nation. It is a terroristic nation. It is a bully. It not only elected a rapist self-dealing criminal imbecile to president, it elected him again, seeking a round two after the utter debacle the first term was, and the disastrous results are exactly what everyone could predict, but you know...this is who America is now.
And a big reason Canada is moving on is that it's pretty clear that the US is a country in spectacular decline, and it is China's century now. Which is maybe why the US is electing disgusting garbage like Trump -- and he's certainly not alone, and there are various garbage "football coach" type creeps filling the entire US political class -- lamenting the position they once held, now going down the Russian/Putin path where they'll accelerate the crash just to reminisce about a past that mostly never existed.
EDIT: I should add that agreements with the US are worthless, and this has been amply demonstrated. As Carney noted, the US' signature is written in pencil, and even agreements signed by this very president mean nothing, and will be dishonoured at the earliest convenience. In recent trade negotiations, where Canada almost made a horrible mistake of accepting ridiculous terms to maintain the status quo as much as possible (sidenote: Canada absolutely must withdraw from USMCA, a Trump-signed and negotiated agreement that the US is in utter defiance of), they asked "so when we sign this, you'll then honour it?", and the US side couldn't even commit to that. They knew that it could be days before the rapist toddler had a twitter tantrum after one of the kleptocrats whispered in his ear and imposed new barriers, tariffs, etc. Like, what is even the point of negotiating with such a farce? A lawless cabal led by just the absolute worst human trash.
Canada isn't an abused spouse that's supposed to sit around and wait while their partner magically undoes all of its threats and (economic) violence. "Undoing" the tariffs in a few years won't magically fix the intense economic damage they've caused to Canadian citizens. The US government being forced to pay hundreds of millions of the illegal tariff money back to corporations didn't magically bring prices back down. The US has completely ruined its reputation in the eyes of most Canadians to the point where nearly every single person I know refuses to travel to the US and many refuse to purchase US goods.
