The purpose of this legislation is to change how the United States government refers to a specific region in Israel and the Palestinian territories. It aims to replace the term "West Bank" with "Judea and Samaria" in all official government materials. This change is meant to reflect what the bill's sponsors believe are the historical names of the area, which they argue should be used in U.S. policy and communications. Key provisions of the legislation include a prohibition on using the term "West Bank" in any government documents, policies, or communications.
