Thought this was a neat article
1. Decision to strike
2. Stealth blitz on nuclear facilities, air defence, and launching capabilities
3. Limit retaliation
4. Underwater warfare
5. Take out Leadership
6. defend DMZ
7. Special Forces missions to hunt remaining nuclear targets and offensive capabilities
Only thing the article doesn't mention though is how China would act in this situation. They would lose their buffer and they would be on the hook to take in millions of North Koreans that don't go South.
Also the truly fanatical North Koreans still in the fight may resort to Guerrilla/Terrorist tactics once the war is over, not only in North Korea, but in the South, and in other countries that their secret units may have been deployed.
