North Korea had warned that its “Christmas gift” to the U.S. would depend on what action Washington took in the talks, leading to concerns that it might conduct a major weapons test. It hasn't conducted any such test, although the U.S. didn't meet a year-end deadline set by leader Kim Jong Un to make concessions.
“You can say that I personally was surprised. But I’m glad also ... there was no Christmas gift,” Ambassador Harry Harris told reporters in Seoul. “Washington was ready for any eventuality, and we were all glad that there was no ICBM test or nuclear test.”
He said both Trump and South Korean President Moon Jae-in “are keeping the door open to negotiations and hoping Kim Jong Un will walk through that door.” “So the ball is in his court," he said. During their first summit in Singapore in 2018, Kim made a vague pledge to work toward complete denuclearization of the Korean Peninsula and the two leaders agreed to improve relations to build lasting peace. Their two subsequent summits and other lower-level meetings haven’t achieved much progress in fleshing out those agreements.
Harris said Trump believes Kim will live up to the Singapore pledge. “President Trump ... is still confident that Kim Jong Un will meet the commitment that they both made together in Singapore,” Harris said. “We should focus on President Trump’s view that there is room for discussion here.”
Prospects for a restart of diplomacy are unclear. In a meeting of his ruling party late last month, Kim said he won't denuclearize if the U.S. persists with its “hostile policy” toward his country. He also said he would soon unveil a new "strategic weapon" and no longer be bound by a weapons test moratorium that he announced at the start of his diplomacy with Trump.
