But considering that they have just announced that they are considering pulling out of the 1952 armistice with S.Korea (technically they've been at war still for the past 50 years), and the Director of the CIA stated last week that intel points to N.Korea being able to hit the US' west coast, how would that shift your viewpoint?

I took that into account. Note that they have a single untested missile. Do they have a NBC warhead for that missile? I don't know. Do they have the guidance system required to hit what they aim at from that far away? I seriously doubt it. Would they risk angering North America (not just the US, but I'm willing to bet Canada wouldn't be very happy either) to deliver a single missile? Again, I seriously doubt it. Have they expressed the willingness to use that WMD, not like Saddam has.
