SINGAPORE — In a day of personal diplomacy that began with a choreographed handshake and ended with a freewheeling news conference, President Trump deepened his wager on North Korea’s leader on Tuesday, arguing that their rapport would bring the swift demise of that country’s nuclear program.

Mr. Trump, acting more salesman than statesman, used flattery, cajolery and even a slickly produced promotional video to try to make the North Korean leader, Kim Jong-un, a partner in peace. He also gave Mr. Kim a significant concession: no more military drills between the United States and South Korea, a change that surprised South Korea and the Pentagon.

After hours of face-to-face contact, in which Mr. Trump even gave Mr. Kim a peek inside his bulletproof presidential limousine, he said he believed that Mr. Kim’s desire to end North Korea’s seven-decade-old confrontation with the United States was sincere.

“He was very firm in the fact that he wants to do this,” Mr. Trump said at the news conference before leaving for home. While cautioning that he could not be sure, Mr. Trump said, “I think he might want to do this as much or even more than me.”
