It is a big decision for them (North Korea), a big undertaking, but it's absolutely the right decision for them. The security, the success, the prosperity of the DPRK does not depend on nuclear weapons. In fact, it depends on relations with others. So this is a moment which I think will be a very important moment in their history, to make this turn, and to turn away from these sorts of weapons and toward interactions with their neighbors and with other countries in the world.
