Adam Smith actually said...

"I think we should maintain our policy of not using them first and using them as a credible deterrent."

"I hope that as we go forward and try to figure out what the new nuclear deterrent needs to look like we don't imagine that we have to have absolutely everything."

"Credible deterrent is not just about how many nuclear weapons you have, but it is also about maintaining an open dialogue."

"We absolutely have to have a nuclear deterrent because, unfortunately, there other countries--and hostile countries like Russia, North Korea--that have nuclear weapons."
