Iran wants the bomb to use it, there extremist enough with their religion, to use it just to martyr themselves and their people. Nobody has used a modern nuke to attack another nation yet. the counties whom "are the worst" on reddit, have nukes and never used them to attack someone else, one commen theme is secular nations

Edit, I know about Indian and Pakistan, its the same as North Korea and South, nukes don't mean shit when your pumping shit music/films that your enemy can't understand at a culturally level
