Everyone assumes there are no means of destroying the North’s artillary. They assume we and the South are going to sit and watch.

There are means of taking them out - ranging from effective counter-artillery barrages to tactical nuclear weapons. What the NK believe though is that either the West/SK knows that they couldn't eliminate the artillery before Seoul was already ravaged, or that the West wouldn't use nuclear weapons. That's why for decades nothing has been done to NK ...apart from useless sanctions.

However, POTUS Trunp is a different flavor of President from the weaklings that have held the seat before, and Kim may have decided to play a game of chance against the one person he shouldn't have played against. POTUS Trump is different enough to show Kim a few tricks that NK will not like.
