At a minimum, any missile being fueled should be destroyed on the pad. If they don't like that, destroy their nuclear research and test facilities. Decapitation strikes to follow. This cat can be declawed.
Crazy as it seems - NKorea is willing to ‘sacrifice’ millions of its starving troops to a ‘first strike’ from SKorea.
They will have fewer mouths to feed. Led by China, Russia, Iran and others, the UN will lift sanctions on NK out of sympathy & take the opportunity to condemn SC and its allies.
This, IMHO, is what that boy king and his generals are planning.
