NPRK cannot hope to be in any sort of conflict for more than a short period of time, but they can do tremendous damage locally in quick order.
As the weeks roll on their ability to 'stay in the fight' will rapidly diminish, so they'd like go for an 'all-in' approach from the word go.
That's why they were/are so hell bent on nuclear capabilities, they simply cannot sustain a traditional war with any hopes of a gain for their efforts.
