Not when they're diverting US ane SK humanitarian aid to the military and Russia is exploiting NK labor ans China exploiting NK resources.
Withiut humanitarian aid propping up the regime, NK would have collapsed long ago. China is unable to sustain them like everyone thinks.
I looked up the numbers: US has provided 1 million dollars to NK in humanitarian aid, UN is 6 million.
I'm no expert, but these numbers don't seem enough to sustain them either.
