"Do you believe if we do not deal with the Iranian nuclear program between now and the end of the year, we are probably in trouble one way or the other?"

"It would be the worst thing for China to face the prospect of additional nations in the area with nuclear weapons."

"Would it severely restrict our ability to deal with the threat that you face today in your backyard; do you agree with that?"

"From our own national security interests, a nuclear-armed North Korea sharing technology with terrorist groups is a real concern; do you agree with that?"
