North Korea and North VietNam are very similar in Communist growing up. They only want to control the world by dirty things such as nuclear weapon, fake money, sex and drugs selling. If you want to get troubles then touch North Korea and North VietNam.
I think they are foxier than Iran or Taliban in killing American and other freedom countries. They may make another 119 problem to American for sure. Especially, Communist North VietNam is the most liars in the world. They smile to you outside but inside, they are keeping many knives and ready kill you !
