Wouldn't be too worried about Kim Jong Un doing any shit with military action at this time.
Unless something extraordinary happens, it seems he is just exaggerating and flexing his military readiness more to get more attention than getting ready for war. I think the likelihood of some military action going on still is not gonna happen barring some unforeseen incident.
For now from my perspective, it appears that Kim is just posturing rather than planning to "make a war happen" or pull a trigger on us Westerns 😀
