No matter, they have no nuclear option. So then you fear that if we don't attack them now they will attack us around the globe? If if we do attack them now they won't? How does that work?
No, I'm sorry my friend what you are looking for is an excuse to attack Iran. Iran does not need an excuse to attack us as we have been screwing them constantly for a very long time. Nothing we do now can change the past. But perhaps by changing the present we can change the future.
