This admin's last broad interpretation involved doing things that had never before been done under IEEPA. Prohibiting Americans from doing business with designated people based on executive fiat has been an extremely common use of IEEPA for decades, and multiple such long-standing emergencies have nothing to do with a concrete threat to the United States. The status quo is very dumb, don't get me wrong, but I don't think there's a lack of clarity about what it is.
