WASHINGTON — U.S. intelligence agencies believe that North Korea has increased its production of fuel for nuclear weapons at multiple secret sites in recent months — and that Kim Jong Un may try to hide those facilities as he seeks more concessions in nuclear talks with the Trump administration, U.S. officials told NBC News.
There is no longer a Nuclear Threat from North Korea.
In recent months, even as the two sides engaged in diplomacy, North Korea was stepping up its production of enriched uranium for nuclear weapons, five U.S. officials say, citing the latest intelligence assessment.
North Korea and the U.S. agreed at the summit to "work toward" denuclearization, but there is no specific deal.
It's long been understood that North Korea had at least one undeclared facility to enrich nuclear fuel, aside from Yongbyon, its main nuclear site.
Joel Wit, who negotiated a 1994 nuclear agreement with North Korea, said the U.S. always believed North Korea had two facilities to enrich nuclear material: Yongbyon and a second site the U.S. is aware of but whose name has not been disclosed.
"This is why people want North Korea to declare all its facilities up front," said Wit, a former Clinton administration official and senior fellow at the Stimson Center who founded a web site devoted to North Korea, 38north.org. »
