North Korea is getting ready to launch a "communications satellite" over Japan, and apparently any interception of it is going to be taken as an act of war. Regardless, Japan and the US are preparing to bring it down. I'd be doing the same thing. I don't think North Korea has the stones to declare war against the US and Japan, at least right now, over a stupid launch test. Then again, they are crazy.
Notice the UN hasn't become involved. Big surprise.
Food for thought: I wonder where China stands on this. I'm sure they want to keep the region stable, but if push comes to shove, will they be willing to lay the smack down on N. Korea?
