We might be wise, after total, massive shock/awe aerial bombardment for 48 hours, stage an Incheon-type west coast landing (combined with massive air drops), that is, 1/2 way up the North Korean coast, somewhere north of Sunan, and attack/move both to the east and then south to take Pyongyang, and to the north to hold the line against advancing PLA coming across the Yalu. They will have some of the northern half of the peninsula, but we must limit their occupation to as little an area as possible. As we divy up the spoils, we run the huge risk of a direct PRC-USA head on clash.
Not to mention the massive outflow of DPRK refugees southward, maybe even to Japan, by every conceivable means and dingy water craft. It will make the Vietnam boat people look like the Newport Beach Christmas Light Festival.
I agree. If possible, landing should be done on Sunan, Nampo which is near Pyongyahng on the Western coast, and Wonsan and Chongjin on the East coast. Denying China the direct access to East Sea(Sea of Japan) must be an important strategic imperative.
Pardon my ignorance but, after 50 plus years of communism NK is a poor, starving country. What are the spoils?
