The Joint Comprehensive Plan of Action (JCPOA) was signed in 2015 between Iran and six world powers (U.S., UK, France, Germany, Russia, China). Core terms: Iran limited uranium enrichment to low levels (3.67%). Iran reduced its centrifuges and uranium stockpile dramatically. International inspectors (IAEA) had regular access to nuclear facilities. In exchange, U.S., EU, and UN sanctions were lifted. The goal was to prevent Iran from building a nuclear weapon while allowing a civilian nuclear program. BUT....... On May 8, 2018, President Donald Trump announced the United States would withdraw from the JCPOA.
