North Korea isn't going to nuke anything, because Kim Jong Un knows that it would be detrimental to his country. Your sick fantasy of getting Trump re-elected is never going to happen.
Kim won't last 20 more years. His country will collapse on its own due to his incompetance and i think the military is actually getting fed up with him a bit. Although it is a dangerous situation having a fat kid in complete control over a nuclear armed country. But really, 20 years and North Korea will collapse and Iran will change drastically too
