HOLD OFF ON THAT NOBEL PRIZE: For weeks now North Korea experts inside and outside government have puzzled over Kim Jong Un’s newfound willingness to commit to negotiating away his nuclear arsenal, without the usual demands and bellicose threats. Kim released three Americans he held as bargaining chips, and promised to shut down his nuclear test site. It all seemed too good to be true.

Now it turns out it may be. North Korea has threatened to call off next month’s historic summit with President Trump and has canceled discussions with South Korea scheduled to take place Wednesday, according to South Korean media, citing the two-week long “Max Thunder” joint  U.S. and South Korean exercise, which the state-run Korean Central News Agency called “a bid to make a preemptive air strike at the DPRK and win the air.”
