"Preventing the proliferation of weapons of mass destruction and their means of delivery is a high priority for my administration."

"I call on North Korea to honor its commitment to abandon all nuclear weapons programs."

"I think it makes more important the topics he discussed today: the danger of the proliferation of weapons of mass destruction."

"We're looking forward to continuing some of the conversations that we've been having both in the EU summit as well as in earlier meetings in NATO."
