That is the question that must be answered. I’m sure they will unleash their conventional artillery, rockets, and missiles at Seoul and the northern portion of South Korea, but that’s largely the extent of their capabilities. The rest of their military would be destroyed in a matter of days if it came to that. It would kinda be like Desert Storm with hundreds of thousands of surrenders or those unwilling to fight. Of course, this is just my opinion.
Be scared. I think bubble boy thinks he can beat us in his little demented pickled, drug addled brain.
N. Koreans probably know their chance of survival is really slim. Especially lower-ranking soldiers who do not have access to well-fortified bunkers deep underground or maze of escape tunnels for safe getaway.
Your scenario does not figure that NK may have thousands of tons of nerve gas.
