So all four of their computers are down???
Seriously, I suspect that China gave us the nod to go ahead. A politically connected general from the PLA just wrote an oped piece saying that China is tired of cleaning up North Korea’s mess. It would not appear in the press, if the government did not condone it at the highest levels.
I wonder if China has told them to cool it. To take any attack form the US and do nothing. Now if they will listen is another question all together.
