Korea and the U.S. have maintained a combined forces command system for a long time. Even if we were to get operational control back, as long as this combined system is maintained, our countries will continue to have combined security, and U.S. forces will continue to play their part in our security.

When it comes to dialogue between South and North Korea and between the United States and North Korea, these can go on parallel tracks. South Korea and the United States can each play a role.

Trump has put the resolution of the North Korean nuclear issue at the top of his priority list, and he has employed a tactic of maximum pressure and engagement, but engagement can only occur if the conditions are right.

For now we must continue to strengthen our sanctions and pressure on North Korea.

The message that we must send to North Korea is twofold: If the North Korean regime believes that it can defend and protect itself through nuclear and missile programs, that is a misjudgment. But if North Korea gives up its nuclear program, we will help it secure and develop itself. We must consistently send these two messages.

As a sovereign state, we should have operational command of our forces returned to us at an appropriate time. Korea and the United States have already reached an agreement where we will receive operational control of our forces when the conditions are met.

It seems Kim Jong Un firmly believes that developing nuclear missile capabilities will provide security and guarantee his regime. We must make it clear that it is not nuclear and missile programs that will protect Kim Jong Un and his regime. The goal of the international sanctions and pressure is to make it unbearable for Kim Jong Un if he does not accept this fact. On the other hand, we are continuously trying to send a message that giving up its nuclear program and coming to the negotiating table is the right path for North Korea to protect itself and achieve its development.
