They’re not in limbo per se, as the court issued a summary judgment to plaintiffs and struck the tariffs down. There are no tariffs now. They were illegal. To get them reinstated, Trump has to appeal, the court has to grant review (which only takes one justice, so review will almost certainly be granted), and then has to reverse the ruling. While the tariffs could be reinstated, I think it’s more likely than not that they won’t.

However, your point about economic stability is well taken. I’ll add to your point that the tariffs have already greatly harmed the U.S. by turning much of the world against us. They’ve forced other countries to look for alternative suppliers, and it is unlikely that they will come back, tariffs or not. They have also triggered boycotts of U.S. products.
