re: Help me with this: So i guess N. Korea thinks the US wants to invade its shithole

No or at least hopefully no (the Juche bubble is the thing that makes North Korea actually going batshit one day a small possibility that does give me pause) -- he's just doing what Dear Old Dad did-- sabre rattle for a pittance because like 50% of his GDP is devoted to defense and there's not really another option (there's no real easy detente here either- he can't shift funds away from defense both ideologically and practically that would risk making the whole house of cards collapse: the former because of decades of conditioning built upon the idea that the outside world poses an dire threat; the latter because even in an authoritarian regime you can't piss off too many elites at once).
