NK has very limited arsenal, there's enough redundant sensors and monitoring systems to verify their launches + midcourse defense to intercept (for now). I hope planners have revisited doctoring to account for new detection tech - more comprehensive, redundant and rapid compared to the cold war - and have formulated different response models to different actors. Right now only Russia has enough nukes to threaten second strike that would warrant immediate retaliation. IMO modern monitoring in general skews conservative responses, it would be pretty rare for malfunctions across multiple detectors to show multiple launces / full mad scenario that require immediate counter-strike. It's almost worth taking risk of hypothetical hit and then counterstrike with certainty then retaliate prematurely on false alarms.
