North Korea is not, nor will not, stop their aim of developing long range missiles with nuclear warheads attached.  Let's not kid ourselves into thinking otherwise.  You've got a fanatical young maniac leading and unfortunately, has his whole regime behind him.  We need not draw anymore lines in the sand nor seek useless/non-effective sanctions.  We all know, or should know,  deep down that there will be a major, major conflict forthcoming.  Prepare for it folks.  Hit them before it's too late.
