I have no doubt that the first time these dipshits try and launch anything with a nuclear payload, every launch facility will be reduced to glass within the hour. Even China can't have them doing that kind of bullshit now that they are tied into the world economy along with the rest of us. Problem is while they have the ability to make nukes, the ability to successfully arm and detonate them from guided missiles is a whole other level of complexity. They are about as likely to nuke themselves as they are their neighbors, unless someone with the tech sold it to them in a moment of weakness, like the crumbling USSR or some shit like that. North Korea is a three pronged fuckup. Chine fucked up in propping them up for so long, the world community fucked up for isolating them to the point where one retard has an entire nuclear arsinal brainwashed to this level, and the US fucked up for wasting all of our political will and military might chasing non-existant threats in Iraq when we should have been on this.
Basically, the first rogue state to actually launch a fucking nuke is going to be the first state nuked entirely back into the stone age by the collective beatdown of every other major nuclear power on the planet. The real question is if said nukings result in a larger focus on the role of nuclear deterrants in the world or everyone goes full retard from that moment on. My guess is that India and Pakistan will want in on the action and probably take down a lot of the middle east with them. Cue the energy crisis, and we are all back to the barter system again...
