The continued demonization of Iran would practically obligate neocons to support a war aganst Iran
to prevent those evil Iranians from developing the dreaded nuclear weapons.
However, more and more people are waking up and realizing that it's now completely impossible to prevent Iran from acquiring nuclear weapons, if they truly wish to acquire tham and most think they do, and launching a war to attempt to stop it would be a complete disaster, and would at best only delay for a bit Iran's development of the nuclear weapons.
Learning to coping with a new reality is actually more intelligent than getting trapped into a dangerous and costly course of action by one's bellicose rhetoric.
