Bush in the run‐up to the Gulf War, and by his son in the aftermath of the 9/11 attacks—the sort of circumstances it was clearly designed to address. See Michael J. Vassalotti and Brendan W.

Anderson and Kathleen Claussen, “The Legal Authority Behind Trump’s New Tariffs on Mexico,” Lawfare, June 13, 2019, https://www.lawfaremedia.org/article/legal-authority-behind-trumps-new-… There’s “some precedent for using IEEPA‐like authorities to impose tariffs.” In 1971, President Nixon used a predecessor statute with similar language, the Trading with the Enemy Act, to hike tariffs on all imports by 10 percent, and a federal appeals court upheld the move.
