We've been working on this option for the last 3 years with more intensity -
But it is still very likely the military option will have to be used - But again, this WOT will be fought at the times and places of our choosing.
And what many our missing is time is on "our" side in the short run (which this nut-cake in Iran seems to understand....thus all the smoke and hype out of Tehran of late).
Oh you're correct that time is on our side. Iran, contrary to a lot of opinion, is years away from a nuke. (160 cents doesn't cut it.)
I only see a military option used in a manner akin to Israel taking out Iraq's nuclear option. I doubt a sustained miltary campaign.
I think we will all be plesantly surprised the day that the Iranian people take to the streets. So go all dictators.
