All the more reasons for Iran to drop their self imposed fatwa on nuclear weapons and get a few, to put an end to interference.
Iran has been on the receiving end of weapons of mass destruction, that is, chemical weapons, by way of US sponsored Saddam Hussein and lost close to half a million of their people. Yet they never for once retaliated with such weapons which to them is against their Islam.
Those half a million dead are part of a still unhealed wound and that is felt and remembered in every city and town in Iran.
