The findings support a new, previously undisclosed Defense Intelligence Agency estimate that North Korea is unlikely to denuclearise.
"We still need to flesh out all the things that underlay the commitments that were made that day in Singapore".
The lone weapons facility that has been acknowledged by North Korea is in Yongbyon, 100 kilometres north of Pyongyang. I got along really well with Chairman Kim.
