On October 8th, Ayatollah Mojtaba Khamenei was elected as Iran's new Supreme Leader, raising concerns about whether he will alter his father's edict against nuclear weapons. Analysts suggest that recent attacks from the United States and Israel could pressure Iran into considering the development of nuclear capabilities, alongside speculation about potential negotiations with the West. A report by The New York Times highlighted fears among experts that Khamenei, unlike his father, might choose to pursue nuclear weapon development, a step that his father Ali Khamenei had explicitly prohibited.

Ali Khamenei announced the ban on acquiring, developing, or using nuclear weapons in 2003. There are also indications that, internally, hardline factions within the Revolutionary Guards have pressured the Supreme Leader to revise this prohibition. Reports have surfaced, such as in The Telegraph, suggesting that the Revolutionary Guards pushed for the withdrawal of the nuclear weapon ban, indicating a shift in the internal political landscape regarding nuclear policy. With Mojtaba Khamenei’s firm stance likely to be more uncompromising than his father’s, analysts are torn between the possibility of increasing tensions and the potential for a negotiated understanding with Western powers.

Mojtaba Khamenei has yet to make any official appearances or statements since his election, keeping his views on the continuation of war or nuclear development unclear. The Supreme Leader holds ultimate authority on decisions regarding nuclear weapons in Iran, and as stated by Evan Cooper from the Stimson Center, the recent U.S. actions during negotiations may instill a belief in Iran that 'nuclear weapons are the only means of deterrence.' There is also speculation that Mojtaba may feel the pressure of changing a well-known and contentious nuclear policy in front of a global audience, particularly given the hereditary controversy surrounding his rise to power.
