That is it. China has full control over its huge border to NK. No way for them to import missile parts unless China is OK with that. Everything of value that NK has and that its elite enjoys is imported from China: Cars, buses, flat-screen TVs, mobile phones...

Plus, China could cut or reduce the oil/gas supply any day to zero.... if they wanted.

I agree. DPRK should keep its nuclear weapons. I am more concerned about nukes in the Indian peninsula when it comes to world security. How good is Pakistan at keeping its nuclear arsenal safe? How good is India? Can we trust them to be competent?

What we should focus on is strengthening the democracy and the economy of ROK so when DPRK fails, ROK can be independent and strong like Germany was in the nineties in its unification. We are nowhere close.
