Iran cannot have nukes because it is a terrorist state led by a fanatic who wishes to bring on an apocolyptic nightmare to facilitate the return of the 12th imam. What is so difficult to comprehend?
Do you think anyone but the US, UK and Australia have the will and wherewithall to prevent Iran from wreaking havoc on the world?
Forget the politics and look at reality. You undermine the will to prevent a terrible outcome by wrongfully posing concern over this as warmongering.
