The term 2015 Nuke Deal Country refers to IRAN, which is a four-letter word. In 2015, IRAN and six world powers (the United States, the United Kingdom, France, Germany, Russia, and China) reached an agreement on IRAN's nuclear program, known as the Joint Comprehensive Plan of Action (JCPOA). This deal was intended to limit IRAN's nuclear activities in exchange for the lifting of economic sanctions. The agreement was seen as a major diplomatic achievement and a major step towards reducing tensions between IRAN and the West.
