Not necessarily. The barrier to a US military action against the NK government has long been the unwillingness of China and SK to go along with it. And China certainly has the military and economic strength to object in some very unpleasant ways. The trouble is that suddenly knocking down the NK government would result in a huge and immediate swarm of North Koreans into China and SK, causing major problems for both those countries. There’s just no infrastructure at all in NK, so absolutely no reason for anyone to stay — they’ll just run for it because they desperately need to find food.
Yes of course Communist China has been a deterring factor in taking military action against N. Korea which would NEVER even be discussed under Bambi’s administration.
Millions of South Koreans would welcome an overthrow of the North Korean slave / insane government....whether from inside or outside of N. Korea.
