The reason for the nuke activity is to blackmail the West into providing food. You would think allies Russia and China would provide food aid for them.
Some allies, huh.
Russia and China have short arms and low pockets.
Some years ago China sent a train load of food to NK and the NK wouldn't return the train....said it was theirs now.
China trains carrying aid to North Korea have history of not returning
"Customs sources said that not enough trains were available to carry the food as trains that had previously crossed the bridge into North Korea had failed to return. "
