The Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), is a landmark international agreement signed in 2015 between Iran and the P5+1 group of world powers (China, France, Russia, the United Kingdom, the United States, plus Germany). Its primary purpose was to restrict Iran's nuclear program, preventing it from developing nuclear weapons, in exchange for the lifting of international sanctions.

The JCPOA established stringent limitations on Iran's uranium enrichment capacity, including caps on the purity and quantity of enriched uranium, as well as restrictions on centrifuges and research and development activities. It also mandated extensive monitoring and verification by the International Atomic Energy Agency (IAEA), granting inspectors unprecedented access to Iran's nuclear facilities. In return for adhering to these provisions, Iran received significant relief from United Nations, United States, and European Union sanctions that had severely impacted its economy. The deal was designed to increase Iran's nuclear breakout time—the time it would theoretically take to produce enough fissile material for one nuclear weapon—to at least one year.

While the original JCPOA faced significant challenges, including the United States' withdrawal in 2018, the pursuit of a diplomatic resolution to Iran's nuclear program remains a high priority. The significance of the Iran nuclear question remains substantial, indicated by a current influence score of 70/100.
