The Iran nuclear deal, also called the Joint Comprehensive Plan of Action (JCPOA), was reached between Iran, the United States, and five other countries. It imposed significant limits on Iran’s nuclear program in return for sanctions relief. The United States withdrew from the deal in 2018 when a new administration, led by Donald Trump, said the deal did not go far enough. In his second term in office, Trump made a new nuclear deal an early foreign policy priority.
