Mr. Trump brushed them off. I get it, I get it, he said.
Where others see flashing yellow lights and slow down, Mr. Trump speeds up. And just like that, in the course of 45 minutes in the Oval Office, Mr. Trump threw aside caution and dispensed with decades of convention to embark on a daring, high-wire diplomatic gambit aimed at resolving one of the world’s most intractable standoffs.
The story of how this came about, assembled through interviews with officials and analysts from the United States, South Korea, Japan and China, is a case study in international relations in the Trump era. A president with no prior foreign policy experience takes on a festering conflict that has vexed the world for years with a blend of impulse and improvisation, and with no certain outcome. One moment, he is hurling playground insults and threatening nuclear war, the next he is offering the validation of a presidential meeting.
Whether the high-stakes gamble ultimately pays off, no one can know. Given two unpredictable and highly combustible leaders, it seems just as likely that the meeting will never take place. If it does occur, the challenges are so steep, the gulf so wide and the history so fraught with misunderstanding, suspicion and broken promises
