[T]he support which Kim Jong-un enjoys is not a mere matter of coercion. - Brian Reynolds Myers

South Koreans do not consider the integrity of their state important enough to go to war for.

To a radical Korean nationalist, the division of the nation, the race, is an intolerable state of affairs. So too is the continued presence of the foreign army that effected that division in the first place.

No one ever said the regime’s legitimacy reposes in the nukes themselves. It rests on a commitment to the unyielding defense and unification of the Korean nation.
