Tough talk, when mixed with a little diplomacy, works. Just look at how President John F. Kennedy handled the Cuban Missile Crisis, or how President Ronald Reagan ended the Cold War.

As Winston Churchill once said, “Diplomacy is the art of telling people to go to hell in such a way that they ask for directions.” And with Trump, his unique style of diplomacy mixed with insults is working — at least for now. During this week’s talks in Beijing, Kim pledged his commitment to denuclearize North Korea and to meet with Trump. “The issue of denuclearization of the Korean Peninsula can be resolved, if South Korea and the United States respond to our efforts with goodwill, create an atmosphere of peace and stability while taking progressive and synchronous measures for the realization of peace.”
