Because Iran isn't following nuclear-policy. The point is they arn't suppose to have weapons (international policy.) What ever is suppose to be done Iran isn't doing that is why there is a problem. Why is it iternational policy that iran cant have nukes if america and other countries can... Also you dont think america, the uk and other countries are still developing more powerful wepaons secretly.... I DO. I dont think its entirly the fact IRAN wants nukes to strike another country, but more that america says they cant have them...
