Pyongyang watchers consider the regime to be so hungry for economic growth, progress and other goodies as to have no pride, no mission, and no commit… - Brian Reynolds Myers

Western observers focus more on the regime's economic failures than the North Koreans themselves do. Remember that it was only in recent modern times that Western societies began expecting the state to secure constant economic growth and rising prosperity. Well into the 20th century people expected little more from the state than that it protect them from foreign powers, and expand the influence or territory of the nation. Prussia was remarkably like North Korea in many ways, yet we remember it as a very successful state. If we judge North Korea by its own standards — instead of by the communist standards we hope its people judge it by — we must admit it has performed very well.

So the question we have to ask ourselves in 2017 is: Why does North Korea risk its long-enjoyed security by developing long-range nukes? Why is it doing the one thing that might force America to attack, to accept even the likelihood of South Korean civilian casualties? And the only goal, the only plausible goal big enough to warrant the growing risk and expense is the goal North Korea has been pursuing from day one of its existence? And I can ask you Matthew what that goal is; I'm sure you know. It's the unification of the peninsula. More concretely, North Korea wants to force Washington into a grand bargain linking de-nuclearization to the withdrawal of U.S. troops. South Korea would then be pressured into a North-South confederation, which is a concept the South Korean left has flirted with for years, and which the North has always seen as a transition to unification under its own control.

They can't understand why any American in his right mind who's not escaping a jail term or something, would voluntarily want to come to [South] Korea and live here.
