If you think Iran has a nuke you are delusional.
Why would it be a crazy assertion to state that Iran has the bomb and is capable at making it at will if necessary?
Iran is quite an advance nation. They are independent, well educated, strong military apparatus, strong government, scientifically strong and well managed. Iranian on per captia is richer than nuclear states as Pakistan, India and NK. They have a strong civilian and military infrastructure and are capable of amassing a warhead if needed.
