The creation of a Middle East Weapons of Mass Destruction Free Zone (WMDFZ) was first proposed by the Shah of Iran in 1974, but since then the idea has not achieved yet significant results. In 1995 and with the endorsement of the NPT, the UN discussed a proposal for “the establishment of an effectively verifiable Middle East zone free of weapons of mass destruction, nuclear, chemical and biological, and their delivery systems” that failed to find enough supports. In 2015, the P5+1 and Iran concluded their JCPOA, which was a promising step towards the WMDFZ that soon vanished after the US withdrawal from the agreement in 2018.
