Good for North Korea for standing up against the "World Police" and it's virtually useless lapdog called the U.N.
Boy oh boy, this is the most blatant and literal form of posturing in the history of nations. The US has a battle ready contingent plonked right on the South/North border. They literally face each other off DAILY. There have also been shots fired through the fence!
They need to relax this a bit and calm the whole situation down.
So South Korea must remove it's only defense as a goodwill gesture
