Below are excerpts of Romney's interview with Scott Pelley for CBS News:
"Scott Pelley: Is it worth going to war to stop an Iranian nuclear weapon?
Mitt Romney: We certainly have to maintain all options that we have. But Iran becoming nuclear and potentially providing fissile material to Hezbollah or other of the groups that are associated with that nation, the potential of those groups bring that fissile material to our continent even to the United States, that's unacceptable. No question in my view that we can put all matter of pressure upon the regime that's there, but they have to also know that a military option is one which we would be willing to consider if they do not take action to dissuade a course towards nuclearization.
Scott Pelley: A Romney administration would not allow a nuclear weapon?
Mitt Romney: It's unacceptable for this nation to have Iran to become nuclear, have a nuclear weapon.
