they can't confirm the boys age....but he's probably like the very late 20's...30 tops.
this kid is probably doing all this (the threats..the rhetoric, the total disregard and disrespect to the US and S. Korea) - trying to push the limits, to get the US to concede and ease up on sanctions...to try and con us to give them money or aid, since the county is all starved...children malnurished, terrible city infrastructures, etc...whereas if we do give them money to shut the fuck up and chill out, all they are gonna do with that, is keep starving their people and use that money to further their quest to build a nuclear weapons - to open these threats up again, 5-10 years down the road (and probably have an active nuclear arsenal, by then).
What the boy doesn't know is his walking that very fine line where if he says one wrong thing or move any more missles close the the eastern coast, to cause further threast to S. Korea, Japan and Okinawa, it could case the downfall of that country and those people.
peace.
