As if things couldn’t get any more tense, North Korea has reportedly moved a missile to the east coast, but South Korea says it isn’t cabable of reaching the United States. Kim Jong-un also closed the border crossing at Kaesong and demanded notice of when the industrial complex’s hundreds of workers from the South would leave. North Korea’s state news agency again threatened to close the complex, despite that it is a key moneymaker for the country. On Wednesday the U.S. boosted its nuclear defense system against North Korea and deployed an advanced missile defense system to Guam as a precaution. And the situation keeps getting more grim, as one of North Korea’s last allies, China, voiced “serious concern” Wednesday.
