With all due respect, based on what basis in Islamic text do you say it is Haram. When all the text and the islamic doctrine says otherwise how can one believe the Fatwas supporting it. Definitely such view seems not to be supported by Sunni regimes and clerics and the Shia Fatwa seem not to have much basis. Repeating a phrase does not make it true nor helps people believing it.Iran was not\will not going to build nuclear weapons but Iran has the capability to build and it is it's right to have this capability due to obvious reasons.
Meanwhile Iran is not that fool to give this capability to US and it's allies. Lybia and Iraq are two governments that trusted US...
Today Iran has this capability and no one dare to attack Iran.
Mr. siavash mass destruction weapons or any sort of weapons that use against civilians are clearly haram in Islam. That's why Iran always has said don't want mass destruction weapons.
The Islamic fatwas prevent Iran to test or build nuclear weapons, but another reason is, if Iran build nuclear weapons UN sanctions will come for Iran and also west will find a stronger reason to attack Iran. Building nukes is not good for security and economy of Iran.
Iranians are wise and know what they are doing.
By the way I didn't say I am supporting building Nuke or I am against it. I said what I think will happen. For sure now any Nuke is counterproductive and I can not make up my mind how it is in 20 years, most probably Pakistan would have 500 million fanatics instead of 120 and Saudi's will be more and more thirsty of Shia eradication.
What I believe is non proliferation is an unrealistic dream that will only happen if all the region is Nuke free which wont happen if China has Nukes though India needs to keep Balance with China and Pakistan with India.
