Don't be so sure Benjamin. A ship engineered as a launch platform could fire the missile from off either coast and then scuttled. The crew either sacrificed or picked up by a second ship with no evidence. All they'd need is plausible deniability and the Ayatollah could sit back and say, "Who, Me?"

There's no nuclear fallout, no craters, Geiger counters read nothing -- pretty soon folks will deny there was a nuclear weapon detonated. The only counter is good intel and a preemptive strike. I'm not sure we as a nation still have the national will to stop it even if we had the intel.
