I don't think anyone on this board knows what they could have planned to overcome such and obstacle but to dismiss it offhand is foolish. Look somewhere along the line it seems people started to take what I was saying as NK would win in a battle with the US over SK. I'm not saying anything other than they may think they have a chance. My one and only point was that they could now take such an action and have nothing to lose and will not be wiped off the face of the earth because the US will not invade NK with a few thousand ICBM nukes aimed at American cities.
Do you understand what escalation is? A NK conventional attack would be met with a similar response from UN forces. And if Kim used nukes then the US would respond in kind.
