Gen David Petraeus, head of Central Command or Centcom, did not elaborate on the plans, but said the military has considered the impacts of any action taken there.
Asked about the vulnerability of Iran's nuclear installations, he told CNN: "Well, they certainly can be bombed. The level of effect would vary with who it is that carries it out, what ordnance they have, and what capability they can bring to bear."
Which may be just as well - I think Iran is belligerent because its leadership is insecure & liable to being overthrown internally. If anyone attacks them unilaterally, it'll only reinforce the political status quo.
