Last night I put up a post in response to Trump’s new tariffs. Key passage:

[U]ntil just the other day there was really no such thing as U.S. manufacturing, Canadian manufacturing or Mexican manufacturing, just North American manufacturing — a highly efficient, mutually beneficial system that sprawled across the three nations’ borders.

But now we have a U.S. president saying that a duly negotiated and signed trade pact isn’t worth the paper it was printed on — that he can impose high tariffs on the other signatories whenever he feels like it. And even if the tariffs go away, the private sector will know that they can always come back; the credibility of this trade agreement, or any future trade agreement, will be lost. So North American manufacturing will disintegrate — that is, dis-integrate — reverting to inefficient, fragmented national industries.

Hence my title, “The end of North America.”

And to think that many people imagined that Trump would be good for business.
