Article does not go as far as to say how China will stop a US attack.....
The last I heard they said that if NK attacks they won't intervene, but if we or SK attack they will, which of course means global war. So they drew a line in the sand and said; "Thalt Shall Not Cross This Line."
Now according to Foreignpolicy.com, the North Koreans have a vast and advanced nuclear weapons program. This means atomic weapons, not thermo-nuclear weapons like the hydrogen bomb, but that they are well on their way to creating that one as well.
The Game Is Over, and North Korea Has Won
Regardless of the headless screaming chickens, the reality is that NK is a puppet and buffer to China. It only exists upon the will of the Chinese leadership. Same could almost be said for Japan as a vassal state of the US now. What you have is a bunch of old perverts running a criminal police state for their own pleasure, and inside that state they can do whatever they want, take whatever they want, rape whomever they want, and so forth. Now I ask if this is actually so different form the supposed leaders we've had and other special people running lose throughout the entire Nato Pac?
This is all a game. There's no way that North Korea should be any kind of serious threat by way of missiles. Not only do we have our own anti-missile defense systems, but what about the anti-missile space based and airborne based defense systems? Ya know, it's a long ways from North Korea to Seattle, let alone Kansas City, and we have aircraft that now fly faster than these missiles do. Sure they are still classified but we all know the USAF has them.
Now there's just no threat here unless they want it to be a threat, and that means acts of high treason which would allow the passage of any missile across the vastness to reach any target in the US. For anyone to pretend otherwise is ignore everything we've dumped trillions of dollars into in the Black Budget, and into primitive public propaganda weapons systems which the general public thinks is where their tax dollars actually went to build those acknowledged weapons systems, and which we all know are ancient outdated systems used to hide where our money is actually going. So anyways there's no way for any missile to reach the US, and probably there's none that could or should be able to even get inside the South Korean Defenses. This is all just a bunch of smoke and mirrors and why I'm not sure why that is just yet.
I am still considering this all a big kids magic act being used to distract all of us.
