I have to agree with Don that the threat is being trumped-up my Mr. Bolten. A question though, why is it that our policy on Iran has not changed in the last 30 years? The US supported the Shah, who's tyranny and cruelty gave rise to the revolution that ended US-Iranian relations, and yet we remain steadfast against having regular diplomacy with them, which may have avoided these developments. We engage China, yet Iran has remained sanctioned and isolated for all of these years of which actual talks may have prevented things going this far. Just a thought.
