Imagine how it would profit Russia and China for NK to do their dirty work for them. Hence why I feel enhanced emp stuffs were sold/loaned/given to NK.
They don't have a relationship like that. China resents NK and Russia hasn't done them any favors since the Soviet Union ended. Having a nuclear NK is no help to China.
Why do you think their end goal is peace and prosperity? You're talking about communists, people who actually believe communism works and kill people to prove it every day.
It's not like both of them have icbms pointed at us or anything, or that China just fabricated some islands on wich to plop military aircraft and missile defenses. NK doesn't poop without asking China first. It seems to me their end goal is to remove the threat America represents to their world hegemony. It amazes me that there are people who think the "leaders" of this world just want peace and light.
