phonetically Kim Jong un sounds more like Gim jeung Un (k is more like a hard G sound) j-ee-uh-ng then uh n

I have family in Seoul, I understand your fear... but it is based on the notion of the unknown.

Here are some facts,

groups in power like to stay in power and do not like anything to destabilize the norms that keep them in power.

North Korea does not have any industry for real export besides weapons

North Korea is essentially a fiefdom of China

China does NOT want ANYTHING to interrupt their modernization and positioning in the global economy. China could crush North Korea like and ant anytime they want.

China is a HUGE source of well everything

Listen the Unites States is NOT in the driver seat here and we are not their true target. The "kid" will be handled by some group until he may or may not be able to turn the tables and run things himself. IF that happens then we should be truly worried.

I am worried like you but really at this time it looks as if they are focused on keeping the continuation of power centralized to the military and communist party. That is their number one goal and we are far down on the list, with the exception of uniting their cowed populace against a outside threat.
