It's interesting how the Chinese see the problem - the bottom line for them.
"Some Chinese military leaders judge that war is inevitable as long as North Korea possesses nuclear weapons. China has plans and intentions to use military force against North Korean nuclear facilities under some circumstances. One of the trip wires for intervention is not military at all, but pollution and fallout from a nuclear test that damages China. China is determined to maintain regional stability at whatever cost. China will support and enforce even stricter sanctions against North Korea."
I have never seen such quick movements from two hostile powers - the US and Red China - working together to stop the madman from gaining weapons of mass destruction. An interesting change from the torpor of the last eight years.
This could work out very well for us, or very poorly, depending on many uncontrollable factors, not the least of which is what the pudgy tyrant in North Korea might do next. Pressure's on.
