North Korea Now Making Missile Ready Nuclear Weapons

[Anomalocaris]

We should be more worried about the Chinese not dealing with the refugee crisis and creating a monsterous humanitarian crisis not seen in asia since pol pot,  than their not being able to deal with the refugee crisis.

Refugees don't come in one giant swarm in 24 hours.   Even millions of refugees on the move still take months, plenty of time for words to spread.  

The Chinese will seal the borders with armed police and blockades.  Refugees without basic food water and medical service will become desperate and try to storm the Chinese blockade.  The Chinese television will show show images of policemen wounded or killed and Refugees will be shown rioting.  Propaganda pitch reminiscent of trumpian tirades against the Mexicans or European rightwimg tirades against Syrian refugees will permeat official airwaves.   And the Chinese will justify violent crack downs on the refugees attempting to enter.  Shots will be fired.  Refugees will be killed,  Intimidating helicopters will buzz around, maybe armored vehicles will be heard clanking not far from the borders.

The word will then pass around the remaining refugees still in the camps, and then pass backwards up the torrent of refugees still flowing towards the border that the Chinese won't let them in, is assembling in great strength at the border, and will shoot to kill against any attempting to force entry.

International outcry can be placated if the Chinese conduct some air drop of supplies on the North Korean side, or just let international aid to come through.

also, I am not convinced that in extremis, most North Korean refugees would rather go to china than go to South Korea.  South Koreans will be much less likely to turn a blind eye, or fire on, their fellow Koreans than the Chinese would.
