Question for Americans: do you guys understand what's happening?

The thing to keep in mind is that the current trade agreement was negotiated and signed by Trump himself. He has spent the last 18 months seeing what a terrible deal it is. He does not want a "deal" into conventional sense, that is an agreement that works for both parties. He needs the counterparty to be humiliated and subjugated. CUSMA (the current agreement he promoted and signed) is bad because it works for all parties, it does not subjugate and humiliate the counterparties.

What happened in these particular trade negotiations? Is that the actual negotiators had something worked out earlier in the week, then at the last minute the US made some new demand that was meant to humiliate Canada, and this tanked the negotiations. What exactly did they ask for? It's irrelevant, the point was humiliation.

Actual trade policy, whether you want access to Canadian dairy market, or lumber tarrif rates or whatever, none of that matters.

Is this a common understanding down south?
