Today on FOX:

HEMMER: You told one of our producers earlier today that you don’t know if it’s true — and you’ve made that clear in our interview here, that you don’t know what the odds are or are not against that — but you hope it’s true. Why do you hope it’s true?

BOLTON: Absolutely. I hope Iran understands that we are very serious, that we are determined they are not going to get a nuclear weapon capability, and unless they change the strategic decision they’ve been pursuing for close to 20 years, that that’s something they better factor into their calculations.
