Over the weekend, Secretary of State Mike Pompeo was in North Korea to continue denuclearization talks and lay the groundwork for a second meeting between President Trump and dictator Kim Jong Un. During that meeting, Kim indicated he would be open to international inspectors visiting the Punggye-ri nuclear test site. That’s a significant step for North Korea but leaves many questions on the country’s commitment to denuclearization.

In May, North Korea made a show of detonating the Punggye-ri test site. Television cameras and news crews were invited to film the dynamiting of the underground tunnels where North Korea’s six nuclear tests had been conducted.

Although that demolition had the optics of a good faith effort, at the time, Kim refused to allow an inspection by international experts that would verify that the site had actually been destroyed. Without inspection and verification, North Korea could easily have detonated the tunnel entrances for show and then reopen them for more tests later.

That type of deception would not be unheard of when it comes to North Korea’s previous flirtations with giving up its weapons. Even this time around as Kim’s regime has repeatedly talked about making good with Washington on its agreement to denuclearize, satellite images have shown that the country has also made efforts to conceal its stockpiles.

A wily administration means that even if the Punggye-ri site has been destroyed and Kim is serious about allowing an international team in for inspection and verification, that the United States and its allies must remain cautiously optimistic about the process and realistic about North Korea’s intentions.

This must also not be considered a new step – the Kim regime decided to blow up the site months ago and is now offering it up again for inspection and marketing it as a sign of progress.

Detonating Punggye-ri is also a far cry from giving up weapons already stockpiled and from dismantling the country’s facility at Yongbyon where it is still produced the fissile material for its nuclear tests. Of course, even if North Korea did dismantle its entire nuclear program, it still remains a threat due to its chemical and biological weapons as well as it cyberattack capabilities.

Those considerations, of course, do not detract from the fact that if the nuclear test site has been destroyed and the Kim regime is serious about allowing an international team in, that is good news and signals further willingness to make real progress towards a deal.

That leaves the ball in Trump’s court. With his upcoming meeting already in the works, he must determine what Kim will ask for in return as a “corresponding step” from the United States and what the U.S. might be willing to do in exchange for the next move.
