I apologize for making a pointless post. If I had thought about it, I would have known what would happen and not wasted my time and that of others.
Why do you try to made a ridicule from what is a perfectly valid statement? Do you think that China is getting involved because of their concern with the rights and sovereingty of South Korea or because of their commitment to Human Rights? They do not care a thing on a lawful abidance diplomatic stance or whatever as the US tries everytime (unsuccesfully). The Chinese have interests and they get involved to see that those interests could be maintained or enforced.
Anyway, it seems that Obama reassured South Korea that the US will support them in a military conflict but no attack have been done against the nuclear weapon manufacturing facilities of this terrorist. Let'ssee what happens now but I bet that this tantrum is a communist "maskirovka" in order to obtain benefits from the US in exchange to "dismantling" the facilities... only to have this happen again and again in four or five years time.
