Five Bigger Threats to National Security than Iran

"I'd actually like to move to Iran," declared the real winner of last week's vice presidential debate -- moderator Martha Raddatz -- "because there's really no bigger national security [threat] this country is facing." Both candidates quickly agreed, and of course both President Obama and Governor Romney have highlighted the threat Tehran poses to the United States and the world in general. Only slightly obliquely, Obama even warned that the United States would consider military action to prevent Iran from going nuclear, a commitment Governor Romney shares.
