Trump has launched a trade war against arguably our closest ally, Canada. We have multiple trade agreements with Canada, but Trump's lawlessness and Congress's complete submission have rendered those laws moot. These trade wars make zero sense from any rational perspective. They have to be viewed through the ongoing psychodrama of Trump 2.0.
During the first maladministration, there was a lot of talk about the "adults in the room." Given the dysfunction of Trump 1.0, those assertions seemed absurd. We are now seeing that they were largely correct. There is no one to rein in Trump's erratic "policies." Of course, they aren't really policy, but rather the extension of his NY real estate tactics. You open a negotiation, seem close to a deal, then you fuck it all up to get more leverage. You "assert dominance" in a way to get the other side to submit to your demands. His routine stiffing of contractors was a prime example of that. They thought they had a contract, but he sued and blustered and reneged on agreements to exhaust the other side.
That doesn't work with sovereign countries with their own power dynamics.
This recent falling out with Canada seems hard to divorce from Trump's other impotent crises. The failure in Iran, the cratering approval ratings, even the defeat of his endorsed candidates in primaries...all of these are expressions of weakness for a man who cannot ever, ever admit weakness. (see the above about NY real estate.)
So, he lashes out in febrile, unpredictable ways. Picking this fight with Canada is just fundamentally stupid. What's more, this is a lifeline to Democratic hopes in Maine, Michigan and other states that do a lot of business with Canada. For someone like El Sayed, this offers an opportunity to change the subject from his association with odious troll Hasan Piker.
It's also worth noting that Trump is ALSO cutting tariffs to import more grounded beef to reduce prices. Trump has lied (shocker!) about the role that tariffs play in inflating prices, but his own plan to lower prices is to...lower tariffs. Basically he's driving prices up with one policy and trying to reduce it in focused ways to help him in November. All he's accomplishing is to piss off farmers, drive home the inflationary nature of his tariffs and probably import tainted beef. Anyone want to gamble on the rigor of the FDA's inspections these days? I guess people still eat at Taco Bell, so maybe they are.
The "adults in the room" really did turn out to be important.
