I always caution people not to laugh when NK rockets and missiles fail. I am a recovering aircraft engineer. You learn just as much from failure as you do success. How many failures did Von Braun have?
Agreed. NK may be pushing things and advancing by fits and starts (in contrast to say Iran which is being disturbingly methodical)... But that doesn’t mean NK is not a threat. This looked like a pretty successful launch of a road mobile canister based weapon, cold gas ejection and all...
