Sen. Lindsey Graham: Military Would Be Last Resort Against Iran Nuclear Threat

WASHINGTON — Sen. Lindsey Graham is siding with a Republican presidential candidate who's calling for military action if all else fails to stop Iran from developing a nuclear weapon.

The South Carolina Republican said on "Face the Nation" on CBS today that he supports "totally, absolutely, without any doubt" former Massachusetts Gov. Mitt Romney's call during a Saturday debate for the military last-resort option to keep nuclear weapons out of Iran.

"If they develop nuclear weapons, the whole region is going to want a nuclear weapon. If you open Pandora's box, if you attack Iran if they get a nuclear weapon, you empty Pandora's box," Graham said.

It's important to "neuter this regime" by destroying its military and persuading Iranians to demand a regime change, he said.
