History

Historical Context

The Joint Comprehensive Plan of Action (JCPOA), finalized on July 14, 2015, aimed to limit Iran's nuclear program by capping uranium enrichment at 3.67% and reducing its stockpile to 300 kilograms. Despite initial compliance, Iran's current stockpile of 441 kilograms of 60%-enriched uranium signifies a breach, highlighting ongoing challenges in nuclear diplomacy and the necessity for renewed negotiations.
