The purpose of this resolution is to call on the United Kingdom, France, and Germany, collectively known as the E3, to reinstate sanctions on Iran. This action is based on concerns that Iran has violated its commitments under a nuclear agreement known as the Joint Comprehensive Plan of Action (JCPOA) and a related United Nations Security Council resolution (UNSCR 2231). The resolution emphasizes the urgency of addressing Iran's nuclear activities and the potential threat they pose to global security.
