What agreement was reached with Iran in 2015?

The agreement reached with Iran in 2015, known as the Joint Comprehensive Plan of Action (JCPOA), specifically aimed to limit Iran's nuclear weapons development for a period of 15 years. This was a pivotal accord reached between Iran and the P5+1 countries (the United States, the United Kingdom, France, Russia, China, and Germany). The agreement required Iran to reduce its stockpile of enriched uranium, cut back on its number of centrifuges, and allow for extensive inspections by the International Atomic Energy Agency (IAEA).

The intention behind the JCPOA was to prevent Iran from developing nuclear weapons capacity while lifting certain economic sanctions that had been imposed in response to its nuclear program. The agreement reflected a diplomatic effort to address global security concerns regarding nuclear proliferation in the Middle East.
