THUNDER RUN TO SEOUL: Assessing North Korea’s War Plan.
My own guess is that ROK forces would fight very well—especially on defense. But there are ways in which North Korea may attempt to undermine ROK morale: Both sides consider the other to be cousins awaiting liberation and this could be used as part of a skillful information operations campaign—particularly if ROK forces seek to advance into the North. The possible combat performance of DPRK forces is even less predictable. On the one hand, the DPRK population has been brainwashed from birth. On the other hand, North Korea’s people fear their own leadership and are often on the brink of starvation. It is possible that they might fight fanatically, but also that, given a chance, they would turn on their leaders. We simply don’t know.
The second main variable is the potential DPRK use of WMD. Finding and killing these will be a high priority for ROK/US commanders, but it is possible that some will survive, especially in the first few days. The North’s leaders may decide to use chemical weapons for battlefield advantage or, if they fail to enter Seoul, may seek to blackmail the ROK government with the possibility of chemical or even nuclear attack against it. Of course the use, or even threatened use, of WMD might invite US retaliation in kind, but a desperate or simply risk-taking Kim regime could gamble that our side would blink first.
The third and related variable is what the DPRK regime would do in defeat. Facing defeat, it is possible that army commanders, or even their troops, would turn on the leadership and depose the regime. On the other hand, if Kim retains enough control over his forces but believes that he is on the brink of being deposed, it is possible that he could—with nothing left to lose—simply unleash whatever WMD he still possesses.
Fascinating read, highly recommended.
