North Korea is run by a mental patient dictator who is about as stable as San Francisco during an earthquake.
The same logic applies to Iran --- accept Iran is a retarded theocracy run by a collection of terrorists.
North Korea sold nuclear technology to Syria --- this has been proven. As such, North Korea has proven they CANNOT be trusted. North Korea armed a country that supports terrorism.
Did you notice how quickly Israel put a foot up Syria's ass over the issue?
