FlyByU: No they don't. NK is a puppet of
China they do not do anything without thee Okay of
China including threats to the USA and its allies. NK would not last 7 days in all out war with SK and the USA.
China will not allow their puppet to be destroyed just like in 1950's when they came to their aid they will do so again. So whatever NK does
China needs to pay as well.
morolf: Claiming they're a mere puppet of
China is an exaggeration, in fact it seems Kim Jong-Un purged his uncle and others because they were seen as too close to
China.
China does have some economic leverage over NK, but they can't just order them around.
And you think war with
China might be a good idea???? Well, good luck then!
