The Washington Post reports:
North Korea claimed to have destroyed its nuclear testing site Thursday afternoon, setting off a series of explosions over several hours, apparently to collapse the underground tunnels in which it had detonated six nuclear bombs over the past 11 years.
The fact that the Kim regime went ahead with the destruction of the Punggye-ri nuclear testing site signals that it is still willing to embark on a diplomatic journey with the United States despite the recent ructions.
Both Washington and Pyongyang have threatened to cancel a summit between President Trump and Kim Jong Un scheduled to be held in Singapore next month. Earlier Thursday, a top aide to Kim said the U.S. must decide whether to “meet us in a meeting room or encounter us at nuclear-to-nuclear showdown.”
