This executive order reverses the previous ban on Nippon Steel's acquisition of U.S. Steel, allowing the deal if the companies sign and comply with a specific national security agreement drafted by the US government. This order permits foreign control of a vital US industrial asset under government-imposed conditions, reversing a prior prohibition. It suggests a political calculation prioritizing conditional investment over outright protectionism. Republicans might overlook ongoing national security risks under the NSA, while Democrats may see insufficient guarantees for domestic workers and industry vitality.
