Trying to be serious here. 
That was unfortunately only about half
not. The frank fact of the matter, as, from what I've seen, has been fairly well established every time the subject of invading NK has came up, is that it's an absolute lose situation for
everyone that would be involved in most invasion scenarios. N+SK comes out worse, any Western support involved comes out worse, any
non-Western support comes out worse, multiple groups (Such as China, who have a non-zero chance of just letting NK sink in the case of an invasion) that may or may not get involved directly either end up worse or no better. No one directly or indirectly involved wins.
More or less the only group that's going to gain any benefit, at bloody all, from an NK invasion is a mostly uninvolved* third party that wants the involved to be weakened. It's a powerful likelihood that even the NK populous would be in a worse position from it for at-minimum several years out.
*Mostly, of course, being because the major powers getting involved and screwing themselves over (which is an unavoidable results of an invasion, pretty much no matter how you cut it) would have global consequences regardless.
