Mr. Trump agreed to the summit in March without requiring any action by the North Korean ruler, or even a clear statement of his intentions. White House officials said the North Korean statement that Mr. Trump reacted to was merely the last straw in a series of negative actions. North Korea canceled a planned meeting with South Korea last week and failed to answer U.S. inquiries about summit planning. That is how previous deals with North Korea have been structured. Instead Mr. Trump has impulsively blown up the process — with potential consequences that he and his administration have not bothered to calculate.
