No one - neither anyone in the administration nor any journalist I've read - recognizes the underlying problem on the Korean peninsula.
North Korea and South Korea, with its US ally, are still at war.
That's right. An armistice was signed July 1953, which stopped the hostilities but that's all. The troops are still lined up on either side of the DMZ. There is still no agreement on how to go forward. Only a peace accord will end the military standoff and define a way forward for commerce, travel between the two regions, etc.
Obviously it is to the MIC's advantage to keep the pot boiling. 28,500 US troops in South Korea. A potential hot conflict just a stone's throw from China and Russia, both of whom are concerned the US will use the conflict as a pretext to make moves on them.
The solution - if anyone cared - would be to offer N. Korea generous terms to de-escalate, allow travel between North and South, while providing them with megatons of food aid, etc.
