When North Korea was complaining about the ROK and the US drilling for an invasion of North Korea they were actually correct.
During the annual Key Resolve drill held last month, the ROK and the US drilled based on a scenario of North Korean Civil War similar to Libya and Syria, upon which the ROK and the US would immediately send in 100K+ ground troops, identify the pro-South factions and crush the opposition military faction by force and successfully occupy North Korea.
So the ROK's official policy is to invade North Korea at the first available opportunity, be it a surprise attack or a internal power struggle/popular revolt and end Kim Dynasty's tyranny.
S.Korea, U.S. Practice Stabilizing N.Korea in Civil War
The annual joint South Korean and U.S. exercises dubbed "Key Resolve" last month for the first time practiced deploying more than 100,000 South Korean troops in North Korea to stabilize the country in case of regime collapse.
The two countries "practiced deploying a large contingent of troops to bring stability in the North in case of civil war in the wake of sudden change there," a government source said on Thursday. "Seoul and Washington practiced preparing for sudden change in the North for the first time during last year's Key Resolve drill, but this was the first time we went on the assumption that South Korean troops would be deployed in the North."
This year's exercise supposed that civil war breaks out due to conflict between hawks and doves in the North Korean military. It envisioned deploying several South Korean Army corps south of Pyongyang to bring hardliners under control and stabilize the North.
