At present time, Iran is not a nuclear-weapon state despite the fact that it pursued a program to develop nuclear warheads in the past, had adhered to the terms of the Joint Comprehensive Plan of Action (JCPOA) since adoption in October 2015 and was verified by all quarterly IAEA reports. Iran also has the largest deployed missile forces in the Middle East with over 1,000 short and intermediate range ballistic missiles, and space-launch vehicle which could be converted into an ICBM. Iran’s nuclear deal restricts their nuclear activities.
There are only three major multilateral arms control agreements and treaties that Iran ratified, they are:
- Nuclear Nonproliferation Treaty – Signed in 1968; ratified in 1970
- Chemical Weapons Convention – Signed in 1993; ratified in 1997
- Biological Weapons Convention – Signed in 1972; ratified in 1973
Iran’s missile program is largely based on North Korean and Russian designs and has benefitted from the Chinese technical assistance. Additionally, Iran was one of the first states that formally called for nuclear weapon free zone in the Middle East.
President Trump, on May 2018 announced that the U.S will withdraw from the KCPOA and reinstate U.S nuclear sanctions on the Iranian regime.
