The way in which Trump is implementing tariffs is utterly at odds with the needs of manufacturers

The way in which President Trump is implementing tariffs is utterly at odds with the needs of manufacturers, says Julian Zelizer .

Zelizer: American manufacturing is already experiencing a renaissance, and if Trump isn’t stopped, he is going to destroy it.

He says the tariffs are going to be throwing off a lot of money to the U.S. If Trump gets his way, they won't be.

Trump 's tariffs are being imposed in a wildly erratic manner, dialed up and down on a practically daily basis via posts on Truth Social .

They also don’t have any clear economic goal.

The result, as I have previously written, is a gigantic increase in economic uncertainty.

Even if some company thought a tariff on Canadian aluminum might make them competitive in the domestic market, they would be fools to try.
