Reuters reports that China has drawn a "red line" with respect to the Korean peninsula, saying they will not allow chaos or war to break out there, and demanding denuclearization. This comes from China's Foreign Minister Wang Yi. Hat tip to Lucianne.com for the link.
Imagine how unhappy a demand for denuclearization will make North Korea's dictator Kim Jong Un. Yet China is the one neighbor North Korea absolutely cannot afford to alienate.
It is fun when two antagonists of the U.S. begin to fight with each other, as for example they've done in Syria. I hope we're subtly encouraging such behavior.
