A Vox report suggested the American negotiating team would call for a three-year suspension of United Nations sanctions on North Korean coal and textiles in return for shuttering a major nuclear site and halting some types of fuel production.
It is not clear if the new talks even broached these or other proposals in any detail. The State Department’s chief negotiator, Stephen Biegun, has said little about the specifics of American proposals, other than making it clear they involved a more step-by-step approach to denuclearization than the all-or-nothing strategy Mr. Trump had used. In Singapore 15 months ago, Mr. Trump said he was confident the denuclearization process would be well on its way within six months. It has not started.
In recent days one of Mr. Trump’s former national security advisers, John R. Bolton, delivered a stinging appraisal of Mr. Trump’s approach without ever naming the president, who fired him a month ago.
Mr. Bolton said he believed that Mr. Kim had no intention of ever giving up his weapons, a statement largely in accord with years of American intelligence estimates dating to before Mr. Trump was elected. Mr. Bolton added that there was little use in the negotiations. Mr. Bolton was excluded from the talks at the end of his time in office, apparently because Mr. Trump believed Mr. Bolton’s hawkish views were more likely to lead to a conflict than to a negotiated settlement.
“I don’t think the North Koreans will ever voluntarily give up enough” to make the negotiations fruitful, Mr. Bolton said last Monday at the Center for Strategic and International Studies in Washington. “There is no basis to trust any promise that regime makes.”
Mr. Trump’s theory has been that the issue can be solved only by direct meetings between the leaders of the two nations, since decades of lower-level talks either broke down or resulted in agreements that fractured apart within a few years.
The most notable success came from a 1994 agreement struck by the Clinton administration, more than a decade before the North tested its first nuclear device. Even that agreement fell apart soon after President Bush was inaugurated, after the United States and South Korea caught the North secretly pursuing uranium enrichment, one of the two pathways to building a nuclear weapon. Every effort that followed collapsed more quickly.
