"Except that the moment the first American soldier steps into North Korea from the south, ten PLA soldiers will enter from the north-west - taking us all back to where we left off in 1953, except with nuclear arms all around."
Why would the PLA risk this? A direct confrontation. Do they need North Korea? Do they have any loyalty to the leadership or people of North Korea? No. They would simply bolster their border defenses on their side of the border and wait. If anything, a merging South/North Korea would hamper South Koreas economy and political leadership for several decades, much like with Germany. China don't need the land or anything else. Risking conflict with the USA would be for nothing China wants.
