South Korean President Lee Jae Myung wants to resume dialogue with North Korea, laying out a three-step plan he hopes will convince Pyongyang to first walk back—and eventually abandon—its nuclear weapons program.

When Presidents Lee Jae Myung and Donald J. Trump meet at the White House, they’ll have much to celebrate as they bolster U.S.-South Korea relations.
