A New Fatwa States That Religious Law Does Not Forbid Use of Nuclear Weapons
On February 16, 2006, the reformist Internet daily Rooz (www.roozonline.com ) reported for the first time that extremist clerics from Qom had issued what the daily called “a new fatwa,” which states that “shari’a does not forbid the use of nuclear weapons.”
The following are excerpts from the Rooz report by Shahram Rafizadeh: 
“When the Entire World is Armed With Nuclear Weapons, it is Permissible to Use These Weapons as a Counter-[Measure]”
“The spiritual leaders of the ultra-conservatives [in Iran ] have accepted the use of nuclear weapons as lawful in the eyes of shari’a.

“[Iranian National Security Council Secretary] Ali Larijani, who is in charge of the nuclear dossier, has spoken to reporters only once since the [IAEA] Board of Governors approved its resolution – and his silence is significant.  But yesterday, the IraNews news agency published recent remarks by Mohsen Gharavian regarding the nuclear issue. Gharavian is a lecturer at the religious schools of Qom , and is a disciple of [Ayatollah] Mesbah Yazdi. In his recent remarks, he said for the first time that the use of nuclear weapons may not constitute a problem according to shari’a. He further said that ‘when the entire world is armed with nuclear weapons, it is permissible to use these weapons as a counter-[measure]. According to shari’a, too, only the goal is important…’
