"The officials' assessments stand in stark contrast to that of US President Donald Trump, who declared following the June 12 summit with Kim that there is no longer a nuclear threat" from North Korea.
North Korea expert David Albright, a former United Nations weapons inspector and president of the Institute for Science and International Security, said the assessments come at a time when "there's a worry that the Trump administration may go soft, and accept a deal that focuses on Yongbyon and forgets about these other sites".
"It has not. Physically, we would be able to dismantle the overwhelming bulk of their programs within a year", Bolton said.
