Iran's nuclear program began in 1957 under Mohammad Reza Shah Pahlavi through the US 'Atoms for Peace' program — the same program that initiated civilian nuclear programs in many countries. Iran signed the Nuclear Non-Proliferation Treaty (NPT) in 1968. After 1979, the program continued under the Islamic Republic despite US opposition.

In 2002, the National Council of Resistance of Iran (NCRI) revealed that Iran had been secretly building uranium enrichment facilities at Natanz and a heavy-water reactor at Arak. This disclosure sparked international concern and more than a decade of negotiations. International sanctions severely damaged the Iranian economy.

The Joint Comprehensive Plan of Action (JCPOA or Iran nuclear deal) was signed in July 2015 between Iran and the P5+1 (US, UK, France, Russia, China, Germany). Iran agreed to limit enrichment to 3.67% and allow inspections; sanctions were lifted. The US withdrew in 2018 under Trump, and Iran progressively exceeded JCPOA limits. By 2024-2026, Iran was enriching uranium to 60-84% — approaching weapons-grade levels.
