Can the yearlong United States-North Korea diplomatic process proceed despite prognostications of its imminent demise after last February’s Hanoi summit? Depending on what the Trump administration does from here on out, the answer is yes.

Indeed, if Washington follows South Korean President Moon Jae-in’s lead when he meets with the president at the White House this week, the U.S.-North Korea relationship can improve to the point in the future when North Korean leader Kim Jong Un decides he no longer needs a nuclear weapons capability for his country’s security.
