The purpose of this legislation, known as the Strategic Assets Protection Act, is to enhance the review process for certain transactions that may impact national security. It specifically focuses on transactions involving real estate, businesses, and critical infrastructure that are related to the United States' nuclear capabilities. Key provisions of the Act require the Committee on Foreign Investment in the United States (CFIUS) to review all transactions completed since January 1, 2017, that involve properties or businesses near facilities critical to the U.S. nuclear triad.
