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 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 and suspicion that the chance that it will lead to a meaningful resolution of the impasse seems remote.
But Mr. Trump has staked his reputation as a deal maker on the presumption that he can personally achieve what no other president has before him.
A Thorny Road
The path to a possible meeting led through a thicket of hostility and feints.
Mr. Kim could match the president he called “the mentally deranged U.S. dotard” bombast for bombast. In a New Year’s Day speech, he said he had “a nuclear button on the desk” that could launch missiles capable of reaching the United States. Mr. Trump responded with a tweet saying that “I too have a Nuclear Button, but it is a much bigger & more powerful one than his.”
But South Korea’s president, Moon Jae-in, focused on the other part of Mr. Kim’s speech, when he declared that he would send athletes to the Winter Olympics, which would be held the next month in South Korea. A flurry of negotiations ensued at Panmunjom, the “truce village” inside the Korean demilitarized zone, that, by the standards of inter-Korean talks, went unusually well.
For the opening ceremony, on Feb. 9, Mr. Kim sent his sister, Kim Yo-jong, while Mr. Trump sent Vice President Mike Pence. The vice president was told of a possible meeting with North Korean officials at the Games if he would tone down his message, not talk about sanctions, not meet with defectors and not bring along Fred Warmbier, whose son, Otto, an American student, died soon after being released from captivity in North Korea.
Mr. Pence opted to do all of those anyway, and the North Koreans canceled the meeting at the last minute. Taking the hard-line position he believed the president wanted him to take, Mr. Pence refused to stand for the entry of the joint Korean team that included athletes from both North and South and made a point of refusing to greet Mr. Kim’s sister, who was just 10 feet away.
Mr. Moon, by contrast, hosted Ms. Kim for a lavish luncheon at the presidential Blue House, and she surprised him with a letter from her brother. She told Mr. Moon that her brother wanted to convene a summit meeting at an early date. The two spent nearly three hours together, with Mr. Moon doing most of the talking.
He said that he really wanted to meet Mr. Kim and improve ties, but that there was a limit to how far he could go without progress in dismantling North Korea’s nuclear program. He urged North Korea to talk to the Americans and said they needed to hurry so as not to lose the rare momentum from the spirit of the Olympics visits.
A Family Envoy
After the unfortunate optics from Mr. Pence’s visit and what some viewed as a missed opportunity, Mr. Trump sent his daughter, Ivanka Trump, to the closing ceremony of the Games. She had dinner with Mr. Moon at the Blue House and briefed him on new sanctions her father would impose on North Korea, then made a public statement to reporters reaffirming the American strategy of “maximum pressure.”
She then headed to Pyeongchang for the last two days of competition. Briefed by Mr. Pence’s staff, Ms. Trump and her team were “incredibly forceful,” as one official put it, in going over the seating plan for the box and the timing and sequencing of arrivals to avoid any surprises.
Ms. Trump proffered a smiling, more open image that went over better in South Korea. She stood for the South Korean athletes, who this time entered the stadium separately from their compatriots from the North, and posed for photographs with famous Korean pop stars. But she too made a point of sending a message; for her guest in the box, she brought Gen. Vincent K. Brooks, commander of American forces in South Korea.
When she attended a curling event, Ms. Trump’s team received word that the North Koreans were on their way in what the Americans thought was an effort to make a scene or prompt her to leave in an embarrassing spectacle. Ms. Trump decided to stay, and the North Koreans in the end did not come.
All Smiles in the North
With the Olympics over, it was time for Mr. Moon to make his move. Last week, he sent two trusted aides on a two-day trip to Pyongyang: Mr. Chung, his national security adviser, and Suh Hoon, his National Intelligence Service director. Flying north, they knew that they were meeting Mr. Kim but not when.
After landing in Pyongyang, they were taken to a riverside guesthouse where they found their rooms equipped with the internet and access to foreign television channels, including CNN. They could even surf South Korean websites, a rare privilege in the totalitarian state. As soon as they unpacked, Kim Yong-chol, a general who heads inter-Korean relations, showed up and said that they were meeting Mr. Kim that evening.
Black limousines took the South Koreans to Azalea Hall in the ruling Workers’ Party headquarters, Mr. Kim’s workplace. They found Mr. Kim and his sister waiting to greet them with broad smiles. Mr. Chung and Mr. Suh were the first South Koreans to set foot inside the party headquarters since the Korean War.
Mr. Chung had barely launched into his talking points when Mr. Kim said “I know” and “I understand you.” Then he laid out his proposal: talks with the United States on denuclearizing his country; a suspension of nuclear and missile tests during the talks; and his understanding that the United States and South Korea must proceed with annual joint military exercises.
The South Koreans found Mr. Kim to be an extremely confident leader. He was closely following foreign news media, knew how he was depicted, and even joked about it. He had studied Mr. Moon’s speeches and overtures toward the North.
He even joked about his missile launches. “I was sorry to hear that President Moon Jae-in had to convene his National Security Council meetings early in the morning because of our missile launchings,” he told the South Koreans. “Now, he won’t lose his early morning sleep any more.”
Mr. Kim agreed to open a direct hotline to Mr. Moon. “Now if working-level talks are deadlocked and if our officials act like arrogant blockheads, President Moon can just call me directly and the problem will be solved,” he said.
And, he added, he was eager to hold a summit meeting with his South Korean counterpart. The South Koreans suggested Pyongyang, Seoul and Panmunjom as possible sites and asked Mr. Kim to choose. Mr. Kim said he would come to the Peace House, a South Korean building inside Panmunjom.
The meeting and dinner, complete with wines and traditional Korean liquor, lasted from 6 p.m. to 10:12 p.m. with much laughter and bonhomie.
After returning to Seoul on Tuesday, the South Korean officials briefed Mr. Moon and then South Korean reporters. After his news conference, Mr. Chung called General McMaster and told him that he was carrying a message from Mr. Kim to Mr. Trump. Only several people at the Blue House knew that the message included a proposal for a meeting with Mr. Trump.
Off to Washington
Mr. Chung flew to Washington and met with General McMaster at the White House on Thursday for half an hour while Mr. Suh met separately with Gina Haspel, the deputy C.I.A. director. The four then got together and were soon joined by other American officials, including Mr. Pence, Mr. Mattis, Dan Coats, the national intelligence director, Gen. Joseph F. Dunford Jr., the Joint Chiefs of Staff chairman, and John F. Kelly, the White House chief of staff.
The South Koreans were not supposed to meet with Mr. Trump until Friday, but when he heard they were in the building, he called them to the Oval Office.
Mr. Kim’s invitation to meet was not a complete surprise to Mr. Trump’s team. An American official said they had learned about it from intelligence agencies on Thursday morning, so before the arrival of the South Koreans, Mr. Trump talked by phone with Secretary of State Rex W. Tillerson, who was traveling in Africa, about the prospect. What he did not tell Mr. Tillerson was that he was going to accept the invitation.
Mr. Trump was eager enough to do it that they discussed a meeting as early as next month. But the South Koreans suggested it would be better to wait until after Mr. Moon’s summit meeting with Mr. Kim in April, which led to a target of May.
Not only did Mr. Trump surprise the South Koreans with his immediate yes, but he also suggested that they make the announcement at the White House.
A stunned Mr. Chung said he had to first talk with his president, so he retreated to General McMaster’s office to prepare a statement and call Mr. Moon on a secure telephone line, waking him up in the middle of the night in Seoul.
Elated, Mr. Trump stuck his head into the White House briefing room to tell reporters there would be an important announcement soon, something he had never done before. Some of the president’s advisers objected to the idea of a foreign official making a statement from the White House lectern, so they had him do it instead on the White House driveway, where visitors speak with reporters.
Still, it was highly unusual for a foreign official to announce an American president’s decision in a major international situation.
Out of the Loop
Mr. Trump’s quick decision caught many off guard, including American allies, as well as Mr. Tillerson. While Mr. Chung headed to the driveway, Mr. Trump called Prime Minister Shinzo Abe of Japan. Mr. Abe has worked assiduously to cultivate a close relationship with Mr. Trump but was left out of the loop.
“I have an impression that the Japanese are not quite well informed,” said Mine Yoshiki, head of a previous Japanese delegation seeking normalized relations with North Korea. “What we have been told is awfully out of tune, I should say.”
The fact that it came on the same day that Mr. Trump slapped tariffs on imported steel that would hurt Japan added to the sting. “Japan has expended a lot of energy trying to support both the letter and spirit of U.S. policy,” said Kristi Govella, assistant professor of Asian studies at the University of Hawaii, Manoa. “So I think it undermines the credibility of Japan when it has gone to that extent to support the U.S.” to be surprised by tariffs and talks.
Mr. Trump did not reach President Xi Jinping of China until the next morning. China has backed Mr. Trump on North Korea, generating good will between Mr. Trump and Mr. Xi. But China refused last month to go along with an American plan to interdict oil tankers bound for North Korea on the high seas, demonstrating that there were limits to how far China would go in punishing Mr. Kim, given the risk of a North Korean collapse on its borders.
Mr. Trump said his conversation with Mr. Xi went well. “President XI told me he appreciates that the U.S. is working to solve the problem diplomatically rather than going with the ominous alternative,” the president wrote on Twitter on Saturday. “China continues to be helpful!”
China’s relationship with North Korea is at a low point. Mr. Xi is said to sneer in private about Mr. Kim and his youth and inexperience. The Foreign Ministry boasted this past week that Mr. Xi had met with more than 50 foreign leaders last year; Mr. Kim was not among them. Mr. Kim refused to see an envoy from Mr. Xi last fall, and no North Koreans showed up for an elaborate Chinese New Year party in Pyongyang last month.
But in response to Mr. Trump’s planned meeting, China is engaged in what some call “exclusion anxiety,” worried about being shut out. China would like the meeting to be held in Beijing, where six-nation talks were held with North Korea during President George W. Bush’s administration, but Chinese analysts doubt Mr. Kim would agree. “China does not want to risk Kim Jong-un saying no and humiliating China,” said Yun Sun, a China expert at the Stimson Center.
For now, Mr. Trump is juggling all these dynamics and preparing for a meeting with the most hermetic leader in the world. To his advisers, Mr. Trump has said he is impressed that Mr. Kim at such a young age has outmaneuvered almost everyone inside and outside his country, but he has added that the North Korean leader is a wild card who cannot be predicted.
Of course, so is he. Mr. Trump vacillates between confidence and fatalism when it comes to North Korea. “The deal with North Korea is very much in the making and will be, if completed, a very good one for the World,” he wrote on Twitter on Friday evening. “Time and place to be determined.”
Also the outcome.
