In 2015, Iran proved the peaceful nature of its nuclear program to the world by signing the Joint Comprehensive Plan of Action (JCPOA) with six world powers.
However, the US’s unilateral withdrawal in 2018 and its subsequent re-imposition of sanctions against Tehran left the future of the deal in limbo.
In 2019, Iran started to roll back the limits it had accepted under the agreement after the other parties failed to live up to their commitments.
Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei issued an official fatwa (religious decree) clearly establishing that any form of acquisition, development, and use of nuclear weapons violate Islamic principles and are therefore forbidden.
