The four-year anniversary of the signing of the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA), which was signed by Iran and the five permanent members of the United Nations Security Council plus Germany, passed on July 14. But with the accord nearing collapse due to the US exit from the deal in May 2018, Iranian officials who had pinned their political futures on the landmark nonproliferation agreement would have preferred the day to go by unnoticed.
With the reimposition of US sanctions, Iran has slowly reduced its nuclear commitments under the JCPOA, most notably announcing that they will increase beyond the 300 kilograms (661 pounds) of low-enriched uranium stockpile and beyond 3.67% enrichment. The United Kingdom, France and Germany (E3) have attempted to salvage the deal, though with little success so far.
