It is not clear what, if anything, North Korea will agree to at the summit or what Kim means by denuclearization. "It might be less dramatic than an explosion, but filling the tunnel up with concrete, or sand or gravel would be best".
A top Trump administration says North Korea's nuclear weapons should be shipped to East Tennessee if that rogue regime makes good on its promise to dismantle its nuclear-testing program.
But underground nuclear test tunnels and shafts are typically created to be sealed by the nuclear bomb's blast wave before radioactive material can escape.
Some experts have said the site had already been rendered unusable after reports that the mountain was on the verge of collapse after the sixth and most powerful underground blast took place in September.
The meeting between Moon and Kim resulted in few specifics and was largely seen as a prelude to the first-ever U.S.
"I think they're done testing". These agencies oversaw the country's 2006, 2009, 2013, 2016, and 2017 missile tests, as well as the 2,500-5,000 metric tons of chemical weapons the organization estimates are in North Korea.
More substantial buildings, including the two largest buildings at the command center, remain intact and no tunnel entrances appear to have been permanently closed yet, probably because North Korea is keeping their dismantlement for a show at the ceremony.
Kim has declared the development of the North's nuclear force complete and that it had no further need for the site.
"It would, however, require North Korea to clear out the test tunnels and rebuild any infrastructure that might be removed or dig new tunnels at the site or elsewhere".
However, the White House was caught off guard by the reports, according to aides.
But no observers from worldwide atomic monitoring agencies have been invited, raising concerns over the openness of the process.
He suggested that could be done at the U.S. nuclear weapons facilities at Oak Ridge, Tennessee.
The site remains open, although no USA nuclear tests have been carried out since 1992. "We'll keenly monitor how the United States and South Korean authorities will react". However, a final attempt by Bush to complete an agreement to fully dismantle North Korea's nuclear weapons program collapsed that December when the North refused to accept USA -proposed verification methods. One official affirmed an assertion from the State Department that it has received no information from Pyongyang about the status of the talks.
When asked if human rights would be on the agenda at the summit, for example, Pompeo said: "America's interest here is preventing the risk that North Korea will launch a nuclear weapon into LA or Denver. We look forward to learning additional details".
The North said the invited reporters will receive visas from the North Korean embassy in China and will fly from Beijing on May 22nd on a charter flight to Kalma airport in Wonsan along with other foreign reporters.
Sen. Lindsey Graham of SC said on CBS' "Face the Nation" Sunday that he thinks Congress would be willing to economically support North Korea once they get rid of their nuclear weapons, and stop trying to develop them.
