The summit between North Korean leader Kim Jong Un and South Korean President Moon Jae-in in Pyongyang was more successful than you describe (“Moon Shot in Korea,” Review & Outlook, Sept. 20). South Korea’s biggest concern isn’t transforming North Korea into a nonnuclear weapons state—it is avoiding a war that could kill millions of Koreans on both sides of the DMZ. Given the threat North Korean artillery poses to Seoul, this is an imminently reasonable, prudent and effective approach for Mr. But Mr. Kim won’t consider denuclearizing—if at all—until he is confident that U.S. policy isn’t predicated on forceful regime change. If President Trump continues to moderate some of the hostility with the North, the once unthinkable—peaceful denuclearization of the Korean Peninsula—will become possible.
