This is supposed to make us take North Korea seriously:
North Korea closed access to a joint factory zone with South Korea on Wednesday, officials said, putting at risk $2 billion a year in trade that is vital for an impoverished state with a huge army, nuclear ambitions and a hungry population.
Taking a step to lose both money and hostages by keeping South Koreans out of the Kaesong joint venture facilities within North Korea is an "escalation" by North Korea?
Huh. I can only quote a wise man in response to Kim Jong Un's order to get away from Kaesong:
Do the North Koreans really count on South Koreans fearing a North Korean collapse more than a North Korean attack?
