Although Kim Jong Un is a very unreasonable leader and has a firm, unreasonable belief that nuclear and missile weapons will protect him and his regime, we will continue to employ all possible means - sanctions, pressure, as well as dialogue - to draw North Korea to the negotiating table for denuclearization. To resolve the issue, we have to add dialogue to the current menu of sanctions and pressure.

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.

President Trump also mentioned that under the right conditions, he is willing to engage in dialogue with North Korea.

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.

During the periods when South Korea played a more active role, the inter-Korean relationship was more peaceful, and there was less tension between the United States and North Korea. The last U.S. administration pursued a policy of strategic patience and did not make any effort to improve its relationship with North Korea. Also, the previous Korean government did not make any such efforts. The result is the reality you see today - North Korea continuing to advance its nuclear and missile program.

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