North Korea’s leader, Kim Jong-un, said he had “good memories” of President Trump and ​saw no reason not to meet him again — as long as the United States stops insisting on dismantling his country’s nuclear arsenal. Mr. Trump, who met Mr. Kim three times in 2018 and 2019, has repeatedly since his return to the White House expressed a willingness to meet Mr. Kim again, boasting of his “good relationship” with the North Korean dictator. North Korea too has reported that Mr. Kim’s relations with Mr. Trump ​were “not bad.” But the speech on Sunday marked the first time since the American leader began his second term that Mr. Kim personally commented on their relationship. “Personally, I still have good memories of U.S. President Trump,” Mr. Kim said during his speech on Sunday. “If the U.S. drops its hollow obsession with denuclearization and wants to pursue peaceful coexistence with North Korea based on the recognition of reality, there is no reason for us not to sit down with the U.S.”
