The issue is that explosions are cool, and it would be unethical to abort something that cool, so the question then becomes: when does the explosion start?
Some say it begins at the moment of detonation, while idiots who don't understand what explosions are insist it starts the moment the rocket is assembled at the factory
Maybe the CIA (or whatever three letter agency is in charge of that OP) is tired of messing with the abort signal and want to try taking out the rockets in flight?
Or maybe, this being the internet it's all false but now the NK is looking for bouys double time
