They are just saber ratteling again. One reason their antics get a moment on our news is because there is no peace treaty to the "Korean war" because they have yet to be happy with any of the terms brought to the table.
They rattle their saber they get a moment on our news.. they get a small group of people on our side scared they win in a small way but in their eyes its a win...
And every time their sabers rattle bigger than this a certain element of our military go on slightly higher "alert" then they were yesterday. Last time that I know of personally (my dh is no longer attached to a unit that has any connection) was about 10-11yrs ago they ratteling sabers left and right. And while DH was activated for something else he was put on alert for this with the possibility he might key word might have to go to Korea.. it was dropped quickly and things went back to normal.
Lol I wonder what is next their rendition of Godzila(sp) eating LA while bombs dropping on it?
