The argument that says North Korean leadership is irrational

Washington Post:

North Korea’s leader is a lot of things — but irrational is not one of them

World leaders, military chiefs and Hollywood have painted Kim Jong Un as an unhinged maniac. North Korea watchers said this is not just wrong but also risks a dangerous miscalculation.

The belief that their hell hole of a country is worth conquering seems to be the driving force about their pursuit of nuclear weapons.  It is a self-defeating irrational move.  The world has been content to let North Korea alone if it would just let the rest of the world alone.  It is now bent on provoking an attack that might lead to the demise of the regime.  The world would be a better place without the current leaders of North Korea.
