[Idealism]

The true leader of Iran issued a mandate against nuclear weapons, that under Shia law, is absolute and binding (which Iran's official state religion is Shi'a).

Fatwa against nuclear weapons

Ayatollah Ali Khamenei has issued a fatwa saying the production, stockpiling and use of nuclear weapons was forbidden under Islam. The fatwa was cited in an official statement by the Iranian government at an August 2005 meeting of the International Atomic Energy Agency (IAEA) in Vienna. <61><62>

A fatwā (Arabic: فتوى‎; plural fatāwā Arabic: فتاوى‎), in the Islamic faith is a religious opinion on Islamic law issued by an Islamic scholar. In Sunni Islam any fatwa is non-binding, whereas in Shia Islam it could be, depending on the status of the scholar.

Most Iranians are Muslims; 90% belong to the Shi'a branch of Islam, the official state religion, and about 8% belong to the Sunni branch, mainly Kurds and Iran's Balochi Sunni.
