That's just bluster. The IEEPA nonsense was already the creative trickery deployed in defense of a novel and prima facia unconstitutional policy. If they had a better argument, they would have made it.
And we know in practice that Trump TACOs out rather than pick real fights with established powers. Markets don't like it when regulatory agencies go rogue vs. the rule of law. They'll just shift gears to something else.
Trump Always Chickens Out (TACO) is a term that gained prominence in May 2025 after many threats and reversals during the trade war U.S. president Donald Trump initiated with his administration's "Liberation Day" tariffs.
The charitable explanation is that he chickens out when confronted with real backlash.The less charitable explanation is that he 'chickens' out after the appropriate bribe has been paid to him.
I think that the tariffs are what he said they were... a starting point for pushing (re)negotiation, and that has largely been successful. This ruling doesn't roll back all those trade deals.
