Mitt Romney says he doesn't believe military action will be necessary to prevent Iran from obtaining nuclear weapons.
The Republican presidential nominee says he discussed the issue with Israeli Prime Minister Benjamin Netanyahu by telephone Friday afternoon. Romney later told reporters traveling with him that it's unclear whether there is any difference between their so-called "red lines" on when launching military action against Iran would be appropriate.
Romney says he can't completely take the military option off the table because Iran needs to take the threat seriously. But he says he does not believe force will ultimately be needed.
Netanyahu argues that an attack on Iran's nuclear facilities may be the only answer.
President Barack Obama also spoke to Netanyahu on Friday.
