2018 is when something finally gives on North Korea

North Korea has long been one of the most secretive nations in the world, and making predictions about it has, correspondingly, long been inadvisable. Keeping that in mind, we’ll make one here anyway: 2018 is when something finally gives on North Korea—one way or another.
It’s unlikely that next year will offer a mere continuation of events in 2017, with North Korea testing ever more advanced weapons, the UN and various nations applying ever stricter sanctions against it, and the rhetoric between Donald Trump and North Korean leader Kim Jong-un—or “dotard” and “little rocket man”—escalating ever higher.
It seems likely, meanwhile, that North Korea will soon be able to reach all of the US with nuclear weapons that can survive long rocket journeys in working order. Some experts caution it might already be there, despite Trump tweeting “It won’t happen!” in January. Trump has been giving strengthened sanctions more time to work, but he doubts they will and has signaled the US will deploy force if necessary to stop the nuclear threat. China, for its part, is already preparing for the flood of refugees expected to cross its border should chaos break out in neighboring North Korea.
