Plans are always drawn up by the US military for every scenario.
One need only be surprised if there wasn't a plan in the Pentagon to invade Australia, not if there was one.
So by itself the existence of a plan to destroy the reign of the mullahs in Iran means little.
And that existence will be denied (routinely) by the Pentagon.
And that denial won't be believed.
As expected, by the Pentagon.
Because it is always far better to "leak" such details to get the mullahs to the negotiating table than to actually put such a plan into action.
And if push comes to shove? And they have to deploy?
Well, in that case you will inevitably find that the strongest conventional weapons will be used on the bunkered facilities and never nuclear (sorry, noo-cloo-ar) weapons.
Even that would be fraught with extreme danger as radioactive material might be spread in "dirty bomb" fashion if a nooclooar facility is hit with conventional weapons.
When Israel hit the Iraqi reactor, it was not in operation, it was under construction and no nooclooar material was dispersed.
