46 Sailor deaths and a sinking of a ship has been unanswered by SK, in terms of military force. I firmly believe that nothing will come of this, besides more back water diplomacy and slaps on the wrist for NK. It will not come down to a conventional war. NK has no one to truly back them, for China is not suicidal. If NK does keep pushing, and some sort of escalating conflict does arise, China would be completely idiotic to back NK. It would then be NK and China versus a vast majority of the rest of the world, which would never happen.
