As a foreign-policy-themed debate got underway in Spartanburg, S.C. Saturday, it quickly became clear that the eight Republican presidential candidates on the stage were more like-minded on how to handle the threat posed by a nuclear Iran than what do with Pakistan.

Almost to a candidate, they charged that President Obama wasn’t doing enough to deter Iran from developing a nuclear weapon.

Mitt Romney went the furthest, refusing to rule out a war with the Middle East nation if economic sanctions failed to work. “We will not allow Iran to have a nuclear weapon,” Romney said.
