The Iran nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA), is a landmark agreement that restricts Iran's nuclear program in exchange for relief from economic sanctions. The deal has been successful in preventing Iran from developing a nuclear bomb and has reduced the risk of nuclear proliferation in the region. However, the deal has been under threat since the United States withdrew from it in 2018. Reinstating the deal is crucial to preventing nuclear proliferation and promoting regional security.
