I suppose it would shock people to learn that the US DoD has, and continually updates, plans for taking on just about every country on the planet - including our putative allies, on the off chance they turn on us or are subsumed by hostile powers. Ergo, by definition we *always* have a plan to bomb Iran; several variations, in fact.
Not that they haven’t given us reason to, uh, further refine said plans recently. Purely a contingency, really. :innocent1_tb:]]>
