While there are other ways Trump can still put in tariffs (Section 232 tariffs on steel and lumber stuff are still in place for example)…

This will put an end to Trump throwing around tariffs willy-nilly to get his way. Well, of course he still can threaten tariffs but those threats will be emptier than they’ve ever been.

Edit: See? His first escalation threat is a 10% tax on Americans for any import whatsoever. Not really directed at any country but their own.
